Duplicate Search. Locates identical files in the system by comparing MD5, SHA256 hashes, or partial content comparison. Supports verification by file name and size. Allows excluding specific directories and using filters by extension. Selects results through automatic or manual selection of items to delete.
Similar Images. Detects visually similar images with different formats, quality, or resolution. Uses visual perception algorithms to compare similarities. Adjustable match sensitivity setting. Supports JPEG, PNG, BMP, and WEBP formats. Shows image preview before any action.
Broken Files. Identifies files with read errors or corrupted structure. Verifies integrity of multimedia files and documents. Attempts to open each file to detect I/O errors. Generates a list of problematic items for repair or deletion.
Empty Directories. Scans and detects folders that contain no files. Option to delete empty directories recursively. Includes access permission verification for system folders. Filters protected directories and folders with symbolic links.
Temporary Items. Locates temporary files and application cache. Identifies residues from previous software installations. Supports cleaning browser cache and system temporary files. Configurable file age setting for deletion.
Large Logs. Finds large log files that consume disk space. Filters by configurable minimum size. Analyzes log content to identify old or unnecessary files. Options to compress or truncate log files.
Duplicate Music. Searches for identical songs using ID3 metadata and audio content analysis. Compares artists, albums, and track titles. Detects different audio encoding qualities. Supports MP3, FLAC, OGG, and WAV formats.
Duplicate Videos. Identifies duplicate video files by visual content or metadata. Compares duration, codec, and video resolution. Keyframe similarity analysis. Supports MP4, AVI, MKV, and MOV formats.
Extension Search. Groups files by extension type to identify uncommon formats. Disk space usage statistics by file category. Filtering by modification date and size. Identifies applications associated with each extension.
Command Line. CLI interface for automation and scripting. Supports redirecting results to files. Silent execution options and detailed logging. Integration with system maintenance scripts.
Graphical Mode. GTK interface for interactive mouse operation. Hierarchical directory tree view. Preview panel for selected content. Visual configuration of scan parameters.
Algorithm Comparison. Multiple file comparison methods: byte-by-byte, cryptographic hash, and partial sampling. Algorithm selection based on file type and performance. Balance between scan accuracy and speed.
Advanced Filters. Filtering criteria by size, modification date, and file attributes. Pattern exclusion using regular expressions. Whitelists and blacklists for specific directories. Filtering by file permissions and ownership.
Result Management. Exporting file lists to CSV or JSON format. Manual marking of items to preserve. Inverse and pattern-based selection. Statistics on freeable space after analysis.

Czkawka was created by Rafał Mikrut starting in 2020. Development began as an open-source alternative to commercial disk cleaning tools. The program is written primarily in Rust, with graphical interface components in GTK. The source code is hosted on GitHub under the MIT license. Contributors maintain versions for Windows, Linux, and macOS. The application receives regular updates with new features and fixes.
