VERY nice piece of Software

6 yr old macbook pro. 500 GB drive. Always filling up with photos and videos. Started looking at all the tools to clean things up and actually downloaded and tried a few other, but found I could not trust them to delete files that were not actually duplicates.

Used photo sweeper, step 1 for me delete duplicates: freed up 39 G of disk space.
I spot checked a number of the dups and delete a few unimportant ones by hand to verify and felt very confident I was not deleting anything that was not really a dup.

This tool has a lot of options and i think in the end it will free up another 100G of storage for me after I run with filters set a bit looser.

briddr about PhotoSweeper, v2.2.6
