Find corrupted files and mass delete them.

[Bruce]

Didn’t I also need the checksum of the files before their corruption to check if it matches?

not necessarily - CRC covers a lot a nerdy stuff.
I don’t believe Windows does the CRC heavy lifting, it’s the disk driver when doing the transfer from the disk surface to the controller and it finds bad sectors that it can’t remap, or has multiple attempt at reading the data

The link would help

Here’s the link : bash - How do I find corrupted archive files? - Unix & Linux Stack Exchange

But the zip files aren’t a problem anymore:

I managed, using my very limited python knowledge, to rewrite the script.

did you try TeraCopy.
I seem to recall it had a copy method that uses CRC checking, if so, that should detect corrupted files as the CRC value would highlight that.

I tried it but it doesn’t find any problem.
A script like the zip one would help but I don’t have any clue on how to let a python script open a photo or a video and check its integrity. If I come up with something I will let you know.

Bad Peggy is exactly what I needed, thank you so much.
I just need something similar for mp3 and mp4 files. I will do some researches tomorrow and keep you updated in case I’ll find anything.

I’ve got some updates.
I’ve found in this forum that you can use ffmpeg to check for the integrity of video files. I’ve made a simple python script and whenever ffmpeg returns with an error it moves the file into another folder, ready to be deleted (ofc after a quick manual double check).
I won’t share it for the same reasons of the other one.
And since I can use this script with mp3 files too I can finally say that this is resolved. Thank you all guys!

bit of mucking around, but you got there in the end, good find.
will close as solved.
