What do I do with the files found in my backup when wanting to restore said backup?

If the file is ThirdPersonAnimBP_3.uasset and you want to use that backup, remove the _3 from it and drag and drop it over the file somewhere inside your Content folder, overwriting it (with Unreal closed of course).

Reopen and enjoy!

I know how to find my backup folder for a particular project…what do I do with the files though???
