diskDedupe

diskDedupe finds duplicate files on your Mac and replaces them with APFS clones — freeing up disk space without deleting a single file.

Save space without losing anything.

When two files are identical, APFS can store them as a single copy on disk while both paths remain fully accessible. diskDedupe automates this process across your entire library, recovering space that traditional cleanup tools miss.
