Compare files, find duplicates

Only for Mac

Mac

New in 2.0: find duplicate files across folders and drives. Checking if files are identical, from the menu bar or Finder, is still free. IdenticalCheck tells you if files are exactly the same, and finds the copies you don't need. It compares what is inside your files, not their names or dates. Files only count as identical when their contents match byte for byte, checked with SHA-256. CHECK FILES IN A MOMENT • Click the menu bar icon and drop files on the panel. It stays open while you work in Finder. • Or select files in Finder, right-click and choose Check if Identical. • Compare two files or many at once. Files with the same contents share a letter, so copies stand out. • See each file's SHA-256 hash, and copy it to verify a download. FIND DUPLICATES ACROSS YOUR MAC • Right-click a folder in Finder and choose Find Duplicates in Folder, or drop a folder on the panel. • Scan folders, whole drives, external disks and network shares together. • Fast with huge folders: a million files are listed in seconds, and only files that could match are read. • Browse results by size, by kind (photos, videos, music, documents, archives) and by location. COMPARE A BACKUP WITH YOUR MAC • Compare A → B finds the files on a backup drive that you already have elsewhere. • Files in A are never touched. Only the copies in B can be removed. SAFE BY DESIGN • One copy of every file always stays. • Auto-select keeps the oldest copy, the newest, the one with the shortest path, or the copies in a folder you choose. • Everything goes to the Trash, and Undo puts it back. • Files that changed after the scan are left alone. • Your Library, your Music and TV libraries, and system folders are skipped, so apps keep working. STAY IN CONTROL • Quick Look previews and Show in Finder for every copy. • Filters to hide kinds of files or small files, and to remove any group from the list. • Exclude folders such as node_modules or .git, or any folder you pick. • Export the results as a CSV file. PRIVATE • Everything happens on your Mac. No account, no network connection, no tracking. Checking files and finding duplicates are free. Moving duplicates to the Trash is a one-time in-app purchase, with no subscription. Requires macOS 15 or later.
