Duplicate finder has all but destroyed my mp3 collection!

I set CCleaner to find my duplicate mp3 files on my Windows 11 laptop, which it did quite easily. Then I made sure that the delete settings would always save the original mp3 and delete any others. WRONG! It just about permanently deleted the lot! 1000s of mp3s gone forever. I used Recuva to try and get them back. I got them back but they were all corrupted and would not play. Your bloody CCleaner has cost me a fortune, let alone deprive me of years of my favourite music. What do you have to say to that? Needless to say, I will not be renewing with you again.

In all honesty that’s why the delete to recycle bin is there.
That said I just ran duplicate finder on my music folder with duplicate songs (same song same artist within seconds of eachother in time) and it didn’t find anything.

I’m not sure what to say about your result, except to tell you at one point I formatted a drive with my music (10s of 1000s of songs) backed up on (was a NAS that i cracked open for the HD) I used Recuva immediatly and to a seperate drive I had. While many were corrupted I was able to recover much of my collection. It took 3 years for me to go (slowly an alphabetical artist letter at a time) through each file and throw away the broken. Many out of that were the same song file overcopied some working and some not. I used MusicBee utilizing it’s inbox system and wave file view. I emplore you go through the recovered maybe not all are gonners.

Edit: You’re using ccleaner 7 right?

Hi there.

I just ran duplicate finder.

I’m on the overview screen where it says all duplicates.

Does ALL mean that a delete wouldn’t leave one???
