How undo a file "revert"

Thanks for all  the replies.

I do backup  my files but I feel the issue is that any time one does someitng in Indesoogn, one should be able to undo it immediately, including "evert," espeially when one reverts accidentally without manually saving first.

If because the technology only works a certain way, e.g. due to memory usage,  then Adobe should change that. The idea is to be the most useful aand  efficient for the user.

Clearly, having to wade through backup files is not efficient/expedient.

Much appreciate your help.

Time Machine is already installed as part of your OS, if you are using it, you can usually recover an earlier version of your file.

Any chance you made backups anywhere? (I like to manually backup current jobs once or twice a day to another hard drive.)

Also, if you used a cloud-based storage service (Dropbox, OneDrive, etc.), it might have saved prior versions automatically.
