diglloydTools IntegrityChecker Java Version: Finds Duplicates, Saved me 100GB!

diglloydTools

A cool new feature of diglloydTools IntegrityChecker 'icj' (Java version) is finding duplicate files; it saved me a whopping 100GB! Over the past few years, I had inadvertently made copies when intending to move files due to a silent Finder bug: if files are marked as locked, the Finder makes copies—yikes!

By using the SHA-1 hashes, exact matches can be found unerringly and all but instantly (once the hashes are done via the 'update' command).

This example is after the 100GB duplications were found and deleted, so there is only 2.4 GiB left of duplicates.

Note: this listing is not displayed fully or properly due to bugs in web browsers.
