 # Changelog
 
+## 2025-11-22 - 13.0.0 - BREAKING CHANGE(SmartFileFactory)
+Refactor to in-memory file API and introduce SmartFileFactory; delegate filesystem operations to @push.rocks/smartfs; bump to 12.0.0
+
+- Introduce SmartFileFactory as the canonical entry point for creating SmartFile, StreamFile and VirtualDirectory instances.
+- Refactor SmartFile, StreamFile and VirtualDirectory to be in-memory representations and accept an optional SmartFs instance for filesystem operations.
+- Delegate low-level filesystem operations to @push.rocks/smartfs (added as a peerDependency); legacy fs/memory/fsStream/interpreter namespace exports removed/deprecated.
+- Add StreamFile.toSmartFile(), VirtualDirectory.loadFromDisk(), and other convenience methods to work with the new factory/smartFs integration.
+- Update tests to use a MockSmartFs and the factory API; add test assets.
+- Documentation and readme updated with migration instructions and examples showing SmartFileFactory.nodeFs() and SmartFs usage.
+- Bumped package version to 12.0.0 — this is a breaking change; consumers should migrate from legacy namespace exports to the factory + @push.rocks/smartfs workflow.
+
+## 2025-08-18 - 11.2.7 - fix(ci)
+Remove .npmrc containing hard-coded npm registry configuration
+
+- Removed .npmrc which contained 'registry=https://registry.npmjs.org/'
+- Avoids committing environment-specific npm registry configuration; rely on user or CI environment settings instead
+
+## 2025-08-18 - 11.2.6 - fix(fs)
+Improve fs and stream handling, enhance SmartFile/StreamFile, update tests and CI configs
+
+- Fix listFileTree to correctly handle '**/' patterns by running both root and nested patterns and deduplicating results.
+- Enhance waitForFileToBeReady: support directory paths (wait for first file) and improved file-stability checks with timeouts and retries.
+- StreamFile improvements: support Web ReadableStream -> Node Readable conversion, better multi-use buffering, more robust fromUrl/fromBuffer/fromStream implementations, and accurate byte-length computation.
+- SmartFile updates: switch fromUrl to SmartRequest, robust rename (optional on-disk rename), safer read/write paths and consistent Buffer handling for hashing and content edits.
+- fs module tweaks: copy/copySync gained replaceTargetDir option, improved toObjectSync error messages, toReadStream now validates existence, and various synchronous/async API consistency fixes.
+- memory module: consistent async/sync write APIs and smartfileArrayToFs formatting/behavior fixes.
+- fsstream: improved stream processing and SmartReadStream robustness (error handling, read logic and watcher improvements).
+- Tests: reformatted and strengthened tests (more explicit assertions, added tests for '**/*.ts' and '**/*' edge cases, updated imports to tapbundle usage).
+- CI/workflows: updated IMAGE and NPMCI_COMPUTED_REPOURL values and switched npmci package install to @ship.zone/npmci in workflow files.
+- package.json: bumped various dependencies, updated test script (timeout, logfile), added typings/main fields, homepage fix, pnpm overrides and minor metadata fixes.
+- .gitignore: added entries for AI tool folders (.claude/, .serena/).
+- Docs/readme: expanded README with clearer examples, features and TypeScript usage; updated readme hints for listFileTree behavior.
+
+## 2025-05-26 - 11.2.5 - fix(dev)
+
+Update dev dependencies and add local permission settings
+
+- Bump @git.zone/tsbuild from 2.5.2 to 2.6.4

+- Add .claude/settings.local.json to configure permissions for Bash(pnpm test:\*)
+
+## 2025-05-24 - 11.2.4 - fix(config)
+
+Add local permissions configuration for pnpm test commands in .claude/settings.local.json
+
+- Introduced .claude/settings.local.json to allow Bash(pnpm test:\*) permissions
+- Ensured local testing commands have proper execution rights
+
+## 2025-05-21 - 11.2.2 - fix(tests/settings)
+
+Improve test assertions and update local settings permissions
+
+- Refactor StreamFile tests to assert content string type using toBeTypeofString
+- Update file existence tests to use resolves.toBeTrue and resolves.toBeFalse for cleaner promise handling
+- Add .claude/settings.local.json to allow specific Bash permissions for pnpm test commands
+
+## 2025-05-21 - 11.2.1 - fix(fs)
+
+Fix inconsistent glob matching in listFileTree and update test imports and dependency versions for enhanced stability.
+
+- Enhanced listFileTree to support \*\*/ patterns by using dual patterns (root and nested) with deduplication.
+- Updated test imports to use '@git.zone/tstest/tapbundle' for consistency across test files.
+- Bumped dependency versions (@push.rocks/lik, smartpromise, smartrequest, glob) in package.json.
+- Added npm configuration (.npmrc) and local settings for improved test verbosity.
+
+## 2025-01-29 - 11.2.0 - feat(fs)
+
+Enhanced copy method with optional replaceTargetDir option for directory replacement
+
+- Added optional 'replaceTargetDir' option to 'copy' and 'copySync' methods in 'fs.ts'.
+- The 'replaceTargetDir' option allows replacing the target directory if both source and target are directories.
+
+## 2025-01-29 - 11.1.9 - fix(fs)
+
+Fix directory handling in copy and copySync functions
+
+- Ensured existing directories at destination are removed before copying over them in async copy.
+- Added a similar check and handling for synchronous copySync when destination is a directory.
+
+## 2025-01-29 - 11.1.8 - fix(fs)
+
+Fixed copy and copySync functions to ensure they always overwrite files.
+
+- Fixed bug in copy function where files were not being overwritten when they already existed at the destination.
+- Fixed bug in copySync function to ensure files are overwritten to match the async function's behavior.
+
+## 2025-01-29 - 11.1.7 - fix(fs)
+
+Refactor copy and copySync functions to simplify return type
+
+- Changed the return type of fs.copy and fs.copySync from boolean to void.
+- Removed unnecessary promise handling in fs.copy.
+
+## 2025-01-29 - 11.1.6 - fix(fs)
+
+Fix issues with fs file copy functions.
+
+- Updated dependencies in package.json.

+
+## 2025-01-07 - 11.1.5 - fix(fs)
+
+Improve waitForFileToBeReady function to handle directories and file stabilization
+
+- Enhanced the waitForFileToBeReady to handle directory paths by checking for file existence within directories and waiting for stabilization.
+- Modified the watcher logic to cater to changes when monitoring directories for file appearance.
+- Introduced a helper function to ensure paths exist and another to resolve the first file in directories.
+- Corrected logic for polling and stabilizing files within directories.
+
+## 2025-01-07 - 11.1.4 - fix(fs)
+
+Fix file existence check in waitForFileToBeReady method.
+
+- Ensured that the directory and file exist before setting up the watcher in waitForFileToBeReady.
+- Changed ensureDirectoryExists to ensureFileExists for correct file path verification.

+- Corrected a TypeScript type in the fs module's checkFileStability function.
+
+## 2025-01-07 - 11.1.2 - fix(fs)
+
+Fix issues in file stability check and directory existence verification in fs module
+
+- Removed unused variable 'isFileAvailable' in 'waitForFileToBeReady'.
+- Fixed logic for ensuring the target directory exists before setting up file stability watcher.
+- Refactored directory existence logic into 'ensureDirectoryExists' function.
+
+## 2025-01-07 - 11.1.1 - fix(fs)
+
+Improve waitForFileToBeReady function for file stability detection
+
+- Enhanced error handling and file stability checks in waitForFileToBeReady function

+# SmartFile Implementation Hints
+
+## Major Architectural Change (v12.0.0)
+
+### Overview
+
+SmartFile has been refactored to focus exclusively on **in-memory file representations** (SmartFile, StreamFile, VirtualDirectory). All filesystem operations have been moved to or delegated to `@push.rocks/smartfs`.
+
+### Key Changes
+
+1. **Factory Pattern Introduction**
+   - New `SmartFileFactory` class introduced
+   - Factory is bound to a `SmartFs` instance (from `@push.rocks/smartfs`)
+   - All file instances are created through the factory
+   - Factory methods: `fromFilePath()`, `fromUrl()`, `fromBuffer()`, `fromString()`, etc.
+
+2. **SmartFile, StreamFile, VirtualDirectory**
+   - Now accept optional `smartFs` parameter in constructor
+   - Filesystem operations (write, read, delete) use `smartFs` if available
+   - Fallback to legacy methods if `smartFs` not provided (for backward compatibility)
+   - Static factory methods moved to `SmartFileFactory`
+
+3. **Separation of Concerns**
+   - **SmartFile** = In-memory file representation (path + content buffer)
+   - **StreamFile** = Lazy-loaded streaming file representation
+   - **VirtualDirectory** = Collection of SmartFiles in memory
+   - **SmartFs** (from @push.rocks/smartfs) = Filesystem operations
+
+### Usage Pattern
+
+```typescript
+import { SmartFileFactory } from '@push.rocks/smartfile';
+import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
+
+// Create factory with SmartFs instance
+const smartFs = new SmartFs(new SmartFsProviderNode());
+const factory = new SmartFileFactory(smartFs);
+
+// Or use default Node.js factory
+const factory = SmartFileFactory.nodeFs();
+
+// Create SmartFile through factory
+const file = await factory.fromFilePath('./data.json');
+await file.write(); // Uses bound smartFs instance
+
+// Create StreamFile
+const stream = await factory.streamFromPath('./large.zip');
+
+// Create VirtualDirectory
+const vdir = await factory.virtualDirectoryFromPath('./src');
+```
+
+### What Belongs Where
+
+**SmartFile/StreamFile/VirtualDirectory (this package)**:
+- ✅ In-memory file representation
+- ✅ Content manipulation (edit, parse, transform)
+- ✅ Loading content FROM sources (factory methods)
+- ✅ Saving content TO destinations (write methods)
+- ✅ Instance metadata (hash, size, mime type)
+- ✅ Collection operations (for VirtualDirectory)
+
+**SmartFs (@push.rocks/smartfs)**:
+- ✅ Filesystem queries (exists, stat)
+- ✅ File operations without content loading (copy, move)
+- ✅ Directory operations (list, create, delete)
+- ✅ Streaming operations (readStream, writeStream)
+- ✅ Provider abstraction (Node.js, memory, S3, etc.)
+
+### VirtualDirectory Collection Methods
+
+VirtualDirectory now has comprehensive collection methods:
+
+**Queries** (operate on in-memory collection):
+- `exists(path)` / `has(path)` - Check if path exists in collection
+- `getFileByPath(path)` - Get SmartFile from collection
+- `listFiles()` - List all SmartFiles
+- `listDirectories()` - List directory paths represented in collection
+- `filter(predicate)` - Filter SmartFiles
+- `map(fn)` - Transform SmartFiles
+- `find(predicate)` - Find SmartFile
+- `size()` - Number of files in collection
+- `isEmpty()` - Check if collection is empty
+
+**Mutations**:
+- `addSmartfiles(files)` - Add files to collection
+- `addSmartfile(file)` - Add single file
+- `removeByPath(path)` - Remove from collection
+- `clear()` - Empty collection
+- `merge(otherVDir)` - Merge another VirtualDirectory
+
+### Backward Compatibility
+
+- Legacy namespace exports (`fs`, `memory`, `fsStream`, `interpreter`) are **deprecated**
+- They remain functional for transition period but marked with `@deprecated`
+- Will be removed in future version
+- Users should migrate to `@push.rocks/smartfs` and `SmartFileFactory`
+
+### Migration Path
+
+**Old (deprecated)**:
+```typescript
+import * as smartfile from '@push.rocks/smartfile';
+
+const file = await smartfile.SmartFile.fromFilePath('./file.txt');
+await file.write();
+
+const exists = await smartfile.fs.fileExists('./file.txt');
+await smartfile.fs.copy('./a.txt', './b.txt');
+```
+
+**New (recommended)**:
+```typescript
+import { SmartFileFactory } from '@push.rocks/smartfile';
+import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
+
+const factory = SmartFileFactory.nodeFs();
+const file = await factory.fromFilePath('./file.txt');
+await file.write();
+
+const smartFs = new SmartFs(new SmartFsProviderNode());
+const exists = await smartFs.file('./file.txt').exists();
+await smartFs.file('./a.txt').copy('./b.txt');
+```
+
+### Testing Considerations
+
+- Tests should use `SmartFileFactory.nodeFs()` or create custom factory with memory provider
+- VirtualDirectory tests can use collection methods without filesystem access
+- Filesystem operations should be tested via `@push.rocks/smartfs`
+
+### Future Plans
+
+- Remove deprecated namespace exports completely
+- Full smartfs integration (remove fallback code)
+- Potentially remove fs-extra, glob dependencies once smartfs is fully integrated
+
+## listFileTree Function Enhancement (ts/fs.ts:367-415)
+
+### Issue Fixed
+
+The `listFileTree` function previously had inconsistent behavior with `**/*.extension` patterns across different systems and glob implementations. Some implementations would miss root-level files when using patterns like `**/*.ts`.
+
+### Solution Implemented
+
+Modified the function to explicitly handle `**/` patterns by:
+
+1. Detecting when a pattern starts with `**/`
+2. Extracting the file pattern after `**/` (e.g., `*.ts` from `**/*.ts`)
+3. Running both the original pattern and the extracted root pattern
+4. Using a Set to deduplicate results and ensure consistent ordering
+
+### Key Benefits
+
+- Guarantees consistent behavior across all systems
+- Ensures both root-level and nested files are found with `**/*` patterns
+- Maintains backward compatibility
+- No performance degradation due to efficient deduplication
+
+### Test Coverage
+
+Added comprehensive tests to verify:
+
+- Both root and nested files are found with `**/*.ts`
+- No duplicate entries in results
+- Edge cases with various file extensions work correctly
+
+This fix ensures tools like `tsbuild check **/*.ts` work reliably across all systems.

-### Quick Start
+## 📚 Quick Start
 
-First, ensure you're working in an environment that supports ECMAScript modules (ESM) and TypeScript. Here’s how you’d generally import and use `@push.rocks/smartfile`:
+### Using the Factory
 
 ```typescript
-import { SmartFile, StreamFile, VirtualDirectory, fs, memory, interpreter } from '@push.rocks/smartfile';
+import { SmartFileFactory } from '@push.rocks/smartfile';
-```
 
-### Working with `SmartFile`
+// Create factory (uses Node.js filesystem by default)
+const factory = SmartFileFactory.nodeFs();
 
-#### Reading Files
+// Load a file into memory
+const file = await factory.fromFilePath('./config.json');
 
-To read from a file and convert it to a `SmartFile` instance:
+// Edit content
-
+await file.editContentAsString(async (content) => {
-```typescript
+  return content.toUpperCase();
-const myJsonSmartFile: SmartFile = await SmartFile.fromFilePath('./somePath/data.json');
-const jsonData = JSON.parse(myJsonSmartFile.contents.toString());
-console.log(jsonData);  // Assuming the file contains JSON content
-```
-
-#### Writing Files
-
-To write data to a file through a `SmartFile`:
-
-```typescript
-const filePath: string = './output/outputData.json';
-const content: string = JSON.stringify({ key: 'value' });
-await memory.toFs(content, filePath);
-```
-
-### Streaming Large Files with `StreamFile`
-
-When dealing with large files, you can use `StreamFile` to handle such files efficiently, minimizing memory usage:
-
-```typescript
-const largeFile: StreamFile = await StreamFile.fromPath('./largeInput/largeFile.mp4');
-await largeFile.writeToDisk('./largeOutput/largeFileCopy.mp4');
-```
-
-### Working with Virtual Directories
-
-Handling multiple files as if they were part of a file system:
-
-```typescript
-const virtualDir = await VirtualDirectory.fromFsDirPath('./data/inputDir');
-await virtualDir.saveToDisk('./data/outputDir');
-```
-
-### File System Operations
-
-`@push.rocks/smartfile` provides a suite of utilities for common file system operations such as copying, deleting, and listing files or directories.
-
-#### Copying a File
-
-```typescript
-await fs.copy('./sourceFile.txt', './destinationFile.txt');
-```
-
-#### Deleting a Directory
-
-```typescript
-await fs.remove('./directoryToDelete');
-```
-
-#### Listing Files in a Directory
-
-```typescript
-const fileList: string[] = await fs.listFiles('./someDirectory');
-console.log(fileList);
-```
-
-### Advanced File Management
-
-For specialized file operations, such as editing the contents of a file or streaming files from URLs, `@push.rocks/smartfile` includes advanced management features.
-
-#### Editing a File’s Contents
-
-```typescript
-const smartFileToEdit: SmartFile = await SmartFile.fromFilePath('./editableFile.txt');
-await smartFileToEdit.editContentAsString(async (content) => content.replace(/originalText/g, 'newText'));
-await smartFileToEdit.write();
-```
-
-#### Streaming a File from a URL
-
-```typescript
-const streamedFile: StreamFile = await StreamFile.fromUrl('https://example.com/file.pdf');
-await streamedFile.writeToDisk('./downloadedFiles/file.pdf');
-```
-
-### Working with File Buffers and Streams
-
-`@push.rocks/smartfile` allows you to easily work with files using Buffers and Streams, facilitating operations like file transformations, uploads, and downloads.
-
-#### Creating a SmartFile from a Buffer
-
-```typescript
-const buffer: Buffer = Buffer.from('Sample data');
-const bufferSmartFile: SmartFile = await SmartFile.fromBuffer('./bufferFile.txt', buffer);
-await bufferSmartFile.write();
-```
-
-### Using `VirtualDirectory` for Complex File Management
-
-`VirtualDirectory` simplifies the management of multiple files that are otherwise scattered across different directories or created at runtime. 
-
-#### Creating a `VirtualDirectory`
-
-To create a `VirtualDirectory` from an existing file directory:
-
-```typescript
-const virtualDirectory = await VirtualDirectory.fromFsDirPath('./someDirectory');
-```
-
-#### Adding More Files
-
-You can add more `SmartFile` instances to your `VirtualDirectory`:
-
-```typescript
-const additionalFiles = [
-  await SmartFile.fromFilePath('./anotherDirectory/file1.txt'),
-  await SmartFile.fromFilePath('./anotherDirectory/file2.txt')
-];
-virtualDirectory.addSmartfiles(additionalFiles);
-```
-
-#### Saving `VirtualDirectory` to Disk
-
-Save your entire `VirtualDirectory` to disk:
-
-```typescript
-await virtualDirectory.saveToDisk('./outputDirectory');
-```
-
-### Utilizing StreamFile for Efficient File Handling
-
-Using `StreamFile` can be especially beneficial for large files or when performing streaming operations.
-
-#### Streaming from a URL
-
-`StreamFile` provides capabilities to stream files directly from URLs, making it easier to work with remote content.
-
-```typescript
-const urlStreamFile: StreamFile = await StreamFile.fromUrl('https://example.com/largefile.zip');
-await urlStreamFile.writeToDisk('./downloadedFiles/largefile.zip');
-```
-
-### Combining Buffer and Stream Approaches
-
-Create `StreamFile` from a buffer for efficient, multi-use streams.
-
-```typescript
-const buffer = Buffer.from('Streaming buffer content');
-const bufferStreamFile = StreamFile.fromBuffer(buffer, 'bufferBasedStream.txt');
-await bufferStreamFile.writeToDisk('./streams/bufferBasedStream.txt');
-```
-
-### Read and Write Operations with StreamFile
-
-Perform read and write operations efficiently using `StreamFile`.
-
-```typescript
-const fileStream = await StreamFile.fromPath('./inputData/largeFile.data');
-await fileStream.writeToDisk('./outputData/largeFileCopy.data');
-```
-
-Check for completeness of your read and write operations, ensuring the integrity of file content.
-
-```typescript
-const readBuffer = await fileStream.getContentAsBuffer();
-console.log(readBuffer.toString());
-```
-
-### Ensuring File Readiness for Streaming
-
-Ensure a file is ready for streaming or create a custom readable stream incorporating data transformation.
-
-```typescript
-const smartReadStream = new SmartReadStream('./incomingData/sample.data');
-smartReadStream.on('data', (chunk) => {
-  console.log('New Data Chunk:', chunk.toString());
 });
+
+// Save back to disk
+await file.write();
 ```
 
-### File Transformation with SmartReadStream
+### With SmartFs Integration
-
-Perform transformations on the stream of data while reading:
 
 ```typescript
-smartReadStream.on('data', (chunk) => {
+import { SmartFileFactory } from '@push.rocks/smartfile';
-  // Perform some transformation
+import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
-  const transformedChunk = chunk.toString().toUpperCase();
+
-  console.log('Transformed Data Chunk:', transformedChunk);
+// Create SmartFs instance with provider
+const smartFs = new SmartFs(new SmartFsProviderNode());
+
+// Create factory bound to this filesystem
+const factory = new SmartFileFactory(smartFs);
+
+// Now all file operations use the smartfs instance
+const file = await factory.fromFilePath('./data.json');
+await file.write(); // Uses smartfs under the hood
+```
+
+## 🎨 Core Components
+
+### SmartFileFactory
+
+The factory is your entry point for creating all file instances:
+
+```typescript
+import { SmartFileFactory } from '@push.rocks/smartfile';
+
+const factory = SmartFileFactory.nodeFs();
+
+// Create from various sources
+const fileFromPath = await factory.fromFilePath('./data.json');
+const fileFromUrl = await factory.fromUrl('https://example.com/config.json');
+const fileFromBuffer = factory.fromBuffer('./file.txt', Buffer.from('content'));
+const fileFromString = factory.fromString('./file.txt', 'Hello World', 'utf8');
+
+// Create StreamFile instances
+const stream = await factory.streamFromPath('./large-file.zip');
+const streamFromUrl = await factory.streamFromUrl('https://example.com/video.mp4');
+
+// Create VirtualDirectory instances
+const vdir = await factory.virtualDirectoryFromPath('./src');
+const emptyVdir = factory.virtualDirectoryEmpty();
+```
+
+### SmartFile Class
+
+Represents a single file loaded in memory:
+
+```typescript
+// Created via factory
+const file = await factory.fromFilePath('./data.json');
+
+// Content access
+const asString = file.parseContentAsString();
+const asBuffer = file.parseContentAsBuffer();
+
+// Content manipulation
+await file.editContentAsString(async (content) => {
+  const data = JSON.parse(content);
+  data.updated = new Date().toISOString();
+  return JSON.stringify(data, null, 2);
 });
+
+// File operations
+await file.write();                          // Save to original location
+await file.writeToDiskAtPath('./output.json'); // Save to specific path
+await file.writeToDir('./dist');            // Save to directory
+await file.read();                           // Reload from disk
+await file.delete();                         // Delete from disk
+
+// Metadata
+const size = await file.getSize();           // File size in bytes
+const hash = await file.getHash('content');  // SHA256 hash
+const stream = file.getStream();             // Get as Node.js stream
+
+// Path information
+console.log(file.path);                      // Relative path
+console.log(file.absolutePath);              // Absolute path
+console.log(file.parsedPath);                // Parsed path components
 ```
 
-### Streaming with SmartReadStream
+### StreamFile Class
 
-Stream data from a `SmartReadStream` to a file efficiently managing large datasets.
+Perfect for handling large files without memory overhead:
 
 ```typescript
-const transformedWriteStream = fs.createWriteStream('./processedData/transformed.data');
+// Created via factory
-smartReadStream.pipe(transformedWriteStream);
+const streamFile = await factory.streamFromPath('./bigfile.zip');
+
+// Or from URL
+const urlStream = await factory.streamFromUrl('https://example.com/large.mp4');
+
+// Or from buffer
+const bufferStream = factory.streamFromBuffer(Buffer.from('content'));
+
+// Write to disk (streams the content)
+await streamFile.writeToDisk('./output/bigfile.zip');
+await streamFile.writeToDir('./output');
+
+// Get content (loads into memory - use carefully!)
+const buffer = await streamFile.getContentAsBuffer();
+const string = await streamFile.getContentAsString('utf8');
+
+// Get as Node.js stream for piping
+const readStream = await streamFile.createReadStream();
+
+// Convert to SmartFile (loads into memory)
+const smartFile = await streamFile.toSmartFile();
+
+// Get file size
+const size = await streamFile.getSize();
 ```
 
-`@push.rocks/smartfile` significantly simplifies the handling of complex file operations in Node.js projects, making these tasks straightforward while maintaining efficiency and ease of use. Explore and leverage these features to enhance your project's file management capabilities.
+### VirtualDirectory Class
+
+Manage collections of SmartFiles in memory:
+
+```typescript
+// Created via factory
+const vdir = await factory.virtualDirectoryFromPath('./src');
+
+// Or create empty
+const emptyVdir = factory.virtualDirectoryEmpty();
+
+// Or from file array
+const files = [file1, file2, file3];
+const vdirFromFiles = factory.virtualDirectoryFromFileArray(files);
+
+// ============================================
+// Collection Queries (in-memory operations)
+// ============================================
+
+// Check existence in collection
+if (vdir.exists('components/Button.tsx')) {
+  console.log('File exists in virtual directory');
+}
+
+// Get file from collection
+const file = await vdir.getFileByPath('utils/helpers.ts');
+
+// List all files
+const allFiles = vdir.listFiles();
+
+// List directory paths represented in collection
+const dirs = vdir.listDirectories();
+
+// Filter files
+const tsFiles = vdir.filter(f => f.path.endsWith('.ts'));
+const largeFiles = vdir.filter(f => f.contentBuffer.length > 10000);
+
+// Map/transform files
+const uppercased = vdir.map(f => {
+  f.contentBuffer = Buffer.from(f.parseContentAsString().toUpperCase());
+  return f;
+});
+
+// Find specific file
+const configFile = vdir.find(f => f.path.includes('config'));
+
+// Collection info
+const fileCount = vdir.size();
+const empty = vdir.isEmpty();
+
+// ============================================
+// Collection Mutations
+// ============================================
+
+// Add files
+vdir.addSmartfile(newFile);
+vdir.addSmartfiles([file1, file2, file3]);
+
+// Remove file
+vdir.removeByPath('old-file.ts');
+
+// Clear all files
+vdir.clear();
+
+// Merge another virtual directory
+vdir.merge(otherVirtualDir);
+
+// ============================================
+// Load/Save (filesystem bridge operations)
+// ============================================
+
+// Save all files to disk
+await vdir.saveToDisk('./dist');
+
+// Reload from disk
+await vdir.loadFromDisk('./src');
+
+// Work with subdirectories
+const subVdir = await vdir.shiftToSubdirectory('components');
+await vdir.addVirtualDirectory(otherVdir, 'lib');
+```
+
+## 🔄 Integration with SmartFs
+
+For filesystem operations beyond loading/saving content, use [@push.rocks/smartfs](https://code.foss.global/push.rocks/smartfs):
+
+```typescript
+import { SmartFileFactory } from '@push.rocks/smartfile';
+import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
+
+const smartFs = new SmartFs(new SmartFsProviderNode());
+const factory = new SmartFileFactory(smartFs);
+
+// Use smartfile for content manipulation
+const file = await factory.fromFilePath('./config.json');
+await file.editContentAsString(async (s) => s.toUpperCase());
+await file.write();
+
+// Use smartfs for filesystem operations
+const exists = await smartFs.file('./config.json').exists();
+await smartFs.file('./config.json').copy('./config.backup.json');
+const stats = await smartFs.file('./config.json').stat();
+
+// List directory with smartfs
+const entries = await smartFs.directory('./src').list();
+```
+
+## 🌟 Common Use Cases
+
+### Configuration File Management
+
+```typescript
+const factory = SmartFileFactory.nodeFs();
+
+// Load, modify, and save config
+const config = await factory.fromFilePath('./package.json');
+await config.editContentAsString(async (content) => {
+  const pkg = JSON.parse(content);
+  pkg.version = '2.0.0';
+  return JSON.stringify(pkg, null, 2);
+});
+await config.write();
+```
+
+### Batch File Processing
+
+```typescript
+const factory = SmartFileFactory.nodeFs();
+
+// Load directory into virtual collection
+const vdir = await factory.virtualDirectoryFromPath('./content');
+
+// Process all markdown files
+const mdFiles = vdir.filter(f => f.path.endsWith('.md'));
+for (const file of mdFiles.listFiles()) {
+  await file.editContentAsString(async (content) => {
+    // Add frontmatter, transform links, etc.
+    return `---\nprocessed: true\n---\n\n${content}`;
+  });
+}
+
+// Save processed files
+await vdir.saveToDisk('./dist/content');
+```
+
+### Download and Process Remote Files
+
+```typescript
+const factory = SmartFileFactory.nodeFs();
+
+// Fetch from URL
+const remoteFile = await factory.fromUrl('https://api.example.com/data.json');
+

+});
+
+// Save locally
+await remoteFile.writeToDiskAtPath('./cache/data.json');
+```
+
+### Large File Streaming
+
+```typescript
+const factory = SmartFileFactory.nodeFs();
+
+// Download large file as stream
+const largeFile = await factory.streamFromUrl('https://example.com/large-dataset.csv');
+
+// Save to disk (streams, doesn't load all into memory)
+await largeFile.writeToDisk('./data/dataset.csv');
+
+// Or get size without downloading entire file
+const size = await largeFile.getSize();
+console.log(`File size: ${size} bytes`);
+```
+
+### Virtual File System for Testing
+
+```typescript
+import { SmartFileFactory } from '@push.rocks/smartfile';
+import { SmartFs, SmartFsProviderMemory } from '@push.rocks/smartfs';
+
+// Use in-memory filesystem for tests
+const memoryFs = new SmartFs(new SmartFsProviderMemory());
+const factory = new SmartFileFactory(memoryFs);
+
+// Create virtual files
+const testFile = factory.fromString('test.txt', 'test content');
+await testFile.write(); // Writes to in-memory filesystem
+
+// Test your code without touching real filesystem
+```
+
+## 🏗️ Architecture
+
+### Responsibility Split
+
+**@push.rocks/smartfile** (this package):
+- ✅ In-memory file representations (SmartFile, StreamFile, VirtualDirectory)
+- ✅ Content manipulation and transformation
+- ✅ Loading content FROM sources (disk, URL, buffer, string)
+- ✅ Saving content TO destinations (disk, stream)
+- ✅ Collection operations (filter, map, find on VirtualDirectory)
+
+**@push.rocks/smartfs**:
+- ✅ Low-level filesystem operations (exists, stat, copy, move, delete)
+- ✅ Directory operations (list, create, remove)
+- ✅ Provider abstraction (Node.js fs, in-memory, S3, etc.)
+- ✅ Streaming (readStream, writeStream)
+- ✅ Transactions and file watching
+

+## 🔧 TypeScript Support
+
+Full TypeScript support with comprehensive type definitions:
+
+```typescript
+import type { SmartFile, StreamFile, VirtualDirectory, SmartFileFactory } from '@push.rocks/smartfile';
+
+const processFile = async (file: SmartFile): Promise<void> => {
+  const content = file.parseContentAsString();
+  // TypeScript knows content is string
+};
+```
+
+## 📦 Backward Compatibility
+
+Version 12.0.0 introduces the factory pattern. Legacy exports are deprecated but still functional:
+
+```typescript
+// ⚠️ Deprecated (still works, but will be removed)
+import * as smartfile from '@push.rocks/smartfile';
+const file = await smartfile.SmartFile.fromFilePath('./file.txt');
+await smartfile.fs.copy('./a.txt', './b.txt');
+
+// ✅ Recommended (new factory pattern)
+import { SmartFileFactory } from '@push.rocks/smartfile';
+const factory = SmartFileFactory.nodeFs();
+const file = await factory.fromFilePath('./file.txt');
+
+// For filesystem operations, use smartfs:
+import { SmartFs, SmartFsProviderNode } from '@push.rocks/smartfs';
+const smartFs = new SmartFs(new SmartFsProviderNode());
+await smartFs.file('./a.txt').copy('./b.txt');
+```
