Question How to check if 100+GB of mixed file types work?

[nicoalbb]

Hey all, been searching the web for some time without any luck:

I recently had to run a file recovery software on a hard drive that is dying, that went well luckily, the problem is that it recovered the whole drive, luckily again I was able to reduce the number of files that were to be saved from 1.3TB to 400GB which in my opinion is a substantial amount I then ran a duplicate file finder and reduced it to 140GB and after that a file sorter to organize those files by year and extension so it would be easier to delete unnecessary files manually which I've been doing for a while now narrowing everything down to only 98GB finally getting to the problem at hand which is that I accidentally discovered that some of the files that I'm keeping don't work and I'm thinking that the duplicate file finder might have deleted the copy of the file that did work, I have no problem in doing all of this work all over again just to make sure that I'm keeping the working copy of the files the thing is that it'll be impossible to check if a million + mixed images, music, videos, documents work doing it 1 by 1, is there any tool that can check each file and then move it elsewhere to repeat the previously mentioned procedure on files that actually work?

Thanks for reading and I hope you can help me!

Recovered files that "don't work" will most likely be damaged or could only be partially recovered. Not at all unusual on a failing drive.
Lesson to be learned here is to have a backup strategy in place at all times, whilst the source drive is healthy.
