Aargh ...

The Monk had a wonderful idea. He knew he had multiple copies of files on his Mac. He knew they were cluttering his system, so he had a brilliant idea. He got the computer to list and identify all the duplicates.

Then it went to pieces. He told it to delete all the duplicates.

Fine, except that the files it removed were all the ones he wanted kept, and now he's faced with the task of finding the copies the computer has kept ...

Experience is what helps us make a different mistake next time ...
