Recover older filename

Hello,
I just realized I renamed wrongly a couple of files. I hoped I could go back with CTRL+Z but it just did the job for 2 files and not for the others. Is there a way to get them back or find somewhere how they were named just before ?

See if the operation is in Edit > Undo List. You may be able to undo it from there. (There's also a "More..." option at the bottom of the menu which opens a more detailed list.)

Failing that, Tools > File Log may at least tell you which files were renamed, depending on the logging detail.

I could not retreive everything but a couple more so thanks for this tip already Leo, cheers !
