Duplicate File Finder
Find and delete duplicate files to reclaim storage
Overview
Duplicate files are one of the biggest storage wasters on any Mac. They accumulate through downloads, backups, file transfers, and everyday use. DiskCleanKit's Duplicate Finder uses advanced algorithms to identify exact duplicate files across your entire system.
Unlike basic duplicate finders that only compare file names, our tool performs deep content analysis to find true duplicates - files that are byte-for-byte identical regardless of their names or locations. This ensures you never accidentally delete unique files.
The intelligent grouping system makes it easy to review duplicates and decide which copies to keep. You can automatically select the oldest, newest, or files in specific locations to remove, saving hours of manual sorting.
