Description
A Plea.
Deanna and I (Your Older Geeks) have been running OlderGeeks.com since 2008 and lately we are seeing a major increase in usage (and cost) but a big decline in percentage of users who donate. Our ad-free and junkware-free download site only works if everyone chips in to offset the revenue that ads on other sites bring in. Please donate on the website today. Every little bit helps. Thank you so much.

Czkawka v9.0.0
"Hiccup" in Polish

A simple, fast and free app to remove unnecessary files from your Windows, Mac or Linux computer.






Features
• Written in memory-safe Rust - almost 100% unsafe code free
• Amazingly fast - due to using more or less advanced algorithms and multithreading
• Free, Open Source without ads
• Multiplatform - works on Linux, Windows, macOS, FreeBSD and many more
• Cache support - second and further scans should be much faster than the first one
• CLI frontend - for easy automation
• GUI frontend - uses GTK 4 or Slint frameworks
• No spying - Czkawka does not have access to the Internet, nor does it collect any user information or statistics
• Multilingual - support multiple languages like Polish, English or Italian
• Multiple tools to use:
- Duplicates - Finds duplicates based on file name, size or hash
- Empty Folders - Finds empty folders with the help of an advanced algorithm
- Big Files - Finds the provided number of the biggest files in given location
- Empty Files - Looks for empty files across the drive
- Temporary Files - Finds temporary files
- Similar Images - Finds images which are not exactly the same (different resolution, watermarks)
- Similar Videos - Looks for visually similar videos
- Same Music - Searches for similar music by tags or by reading content and comparing it
- Invalid Symbolic Links - Shows symbolic links which point to non-existent files/directories
- Broken Files - Finds files that are invalid or corrupted
- Bad Extensions - Lists files whose content not match with their extension
