release_2.5.0

7-Zip CLI Fallback for .7z Archives

SharpCompress can struggle with certain .7z archives (especially those using newer compression methods). This release adds an automatic fallback to the 7-Zip command-line tool when SharpCompress fails.

Smart Temp Drive Selection

When the system temp drive runs low on space during archive extraction, the app now automatically searches alternative local drives with sufficient free space. This prevents failures when processing large archives on systems where the C: drive is nearly full.

Archive Info Pre-Scan

Before extraction, archives are now analyzed to determine their uncompressed size and file count. This enables the drive space check to be smarter and provides a more accurate progress indicator before extraction begins.

Enhanced Error Handling

• Added bug reporting for failures in ExternalToolService, ExtractXisoService, NativeIsoIntegrityService, and XisoWriter
• Disk space checks now include a 10% safety buffer (minimum 200MB) to account for filesystem overhead

Under the Hood

• Upgraded SharpCompress to 0.49.0
• Over 30 new unit tests covering DisplayInstructions, Formatter, GenerateFilename, and ConvertToPastTense

release_2.4.0

Encrypted Archive Detection

Password-protected archives (ZIP, RAR, 7z) are now automatically detected. Instead of cryptic "bad state" or "end of stream" errors, you'll see a clear message explaining the file is encrypted and guidance on how to extract it manually. This prevents confusion when processing archives downloaded from sites that password-protect their downloads.

File Lock Detection

If an archive is currently open in another program (file explorer preview, antivirus scan, download manager, etc.), the application now detects this before attempting extraction and provides a clear error message asking you to close the locking program.

Retry Logic with Exponential Backoff

Archive analysis and extraction now include automatic retry on transient I/O errors (up to 3 attempts with increasing delays), reducing failures caused by temporary file locks or brief network interruptions.

Drive Readiness Check

Before processing files, the application verifies the target drive is actually ready — preventing confusing errors when working with disconnected external drives or network shares that have gone offline.

Improved Shutdown Handling

• The application now properly cancels and disposes background operations when closing
• Added a safety net that force-terminates the process if the UI becomes unresponsive during shutdown (prevents the app from lingering in the background)
• Closing the window while an operation is running is now smoother and more reliable

Code Quality & Maintainability

• Extracted GetXgdType method for cleaner Redump ISO type detection
• BuildFullMessage made testable (now internal static)
• UpdateChecker now uses injected version string instead of runtime assembly reflection
• Removed unused ApplicationSettings model and orphaned methods (GetUncompressedArchiveSizeAsync, RobustMoveFileAsync)
• Added 4 new unit test files, bringing the test suite to 173 passing tests
• Async methods now follow the Async suffix naming convention
• NuGet dependencies updated: SharpCompress 0.48.1, Microsoft.Extensions.DependencyInjection 10.0.8

• Update SharpCompress package.
• Improve exception reporting with environment details.

release_2.2.0

• Add a helper method to detect when output drives or network paths become unavailable. When such errors occur, the batch operation is now stopped immediately rather than continuing to process files that cannot be written.
• Improves error detection by checking specific HRESULT codes.
• Adds Czech translation support for device not ready errors.
• Batch operations will now stop immediately on fatal environmental errors instead of marking files as failed and continuing.
• Implement IsDiskSpaceError check to stop batch processing when the  output drive is full.
• Improve the bug reports.
• Update SharpCompress dependency to version 0.47.3.

release_2.1.2

1. New Features & Improvements

• Disk Space Verification: Added a CheckDiskSpace method that calculates the total size of an archive's contents and verifies if the destination drive has sufficient free space before starting the extraction.
• Extraction Metadata: The logs now display the total size of the files to be extracted alongside the file count and archive format.
• Dependency Update: Updated the SharpCompress library from version 0.47.0 to 0.47.1.

2. Enhanced Error Handling

• Specific Archive Exceptions: Added dedicated catch blocks for ArchiveException and ArchiveOperationException. This provides users with clearer feedback if an archive is corrupt, invalid, or in an unsupported format.
• Disk Space Alerts: Improved the reporting of "not enough space" errors, providing a user-friendly message suggesting the user free up space rather than showing a generic IO error.
• Refined Bug Reporting Filters: Updated the exception filtering logic to ensure that environmental issues (like low disk space) and archive-specific errors (like corruption or invalid passwords) are handled gracefully and not flagged as application bugs.

3. Code Cleanup

• Simplified the extraction loop by pre-filtering entries to exclude directories.
• Added necessary imports (SharpCompress.Common) to support new exception types.

release_2.1.1

• Resource Management: External conversion processes now run with BelowNormal priority to ensure the system remains responsive during heavy tasks.
• UI Stability: The logging service now automatically truncates long logs to prevent the interface from freezing.
• Cancellation Handling: New logic ensures that if a conversion is canceled, any partially created files are automatically deleted to prevent data clutter.
• Asynchronous Improvements: Conversion operations are now explicitly wrapped in background tasks to keep the UI fluid.

release_2.1.0

🚀 UI Overhaul & Stability Improvements
