Tool to compare files (content)

[Church of Noise]

Lately, I've been getting all files / backups / pictures I had on several harddrives on 1 server.
However, it seems quite a few files are doubles (mainly pictures that exist more than once, but under different file names eg.)

Is there a good software tool to identify and clean up?

Thanks!

The two I've used before are clonespy on my home computer as it's a bit of freeware or at work I use Fast Duplicate Pro

Checksums - md5sum is the same if the content is the same but the file names are different.

There is a mathematical chance of different contents having the same checksum, so don’t try on it for anything important.

I’d take the risk on personal photos/music files
I’d not take the risk on vaccination records for 70million people.

Brilliant! Thanks for the quick reply, clonespy is running and looks to be doing exactly what I wanted!

Call me old fashioned but would the command line FC work?

Can that work en masse for dozens of folders? A quick google suggests it's only for individual files?

If you're keen, you could probably knock something up in Powershell (assuming you're running Windows).

CCleaner has this feature I think.

In the past, I've used a file rename to rename the file using the file data.

Ie "year-month-day-hour-min-sec-camera-dimensions-filesize.jpg" etc
