+## 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.

+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.
+- Handled ENOENT errors correctly to retry file existence checks until timeout is reached.
+

+Fix TypeScript type issue in fs module
+
+- 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
+- Added timeout feature for file readiness check
+- Improved directory access check before file availability check
+
+## 2025-01-07 - 11.1.0 - feat(SmartFile)
+Add rename functionality to SmartFile class
+
+- Implemented a new method to rename a file within the SmartFile class.
+- The rename method updates the file path and optionally writes the renamed file to the disk.
+
+## 2024-12-15 - 11.0.23 - fix(fs)
+Handle errors in toObjectSync method
+
+- Added error handling in toObjectSync function to capture and provide more informative error messages.

-#### Uploading a File
+### Using `VirtualDirectory` for Complex File Management
 
-Stream files or buffers can be integrated with web frameworks to handle file uploads efficiently, utilizing streams to reduce memory footprint.
+`VirtualDirectory` simplifies the management of multiple files that are otherwise scattered across different directories or created at runtime. 
 
-### Conclusion
+#### Creating a `VirtualDirectory`
 
-With `@push.rocks/smartfile`, managing files in Node.js using TypeScript becomes significantly more straightforward and efficient. Utilizing the provided classes and methods, you can handle a wide range of file operations, from basic read/write tasks to complex operations such as virtual directory management and file streaming, with minimal boilerplate code and maximum efficiency.
+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());
+});
+```
+
+### File Transformation with SmartReadStream
+
+Perform transformations on the stream of data while reading:
+
+```typescript
+smartReadStream.on('data', (chunk) => {
+  // Perform some transformation
+  const transformedChunk = chunk.toString().toUpperCase();
+  console.log('Transformed Data Chunk:', transformedChunk);
+});
+```
+
+### Streaming with SmartReadStream
+
+Stream data from a `SmartReadStream` to a file efficiently managing large datasets.
+
+```typescript
+const transformedWriteStream = fs.createWriteStream('./processedData/transformed.data');
+smartReadStream.pipe(transformedWriteStream);
+```
+
+`@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.
