The folder you copy your file (any file that has some importance to you) to should be a onedrive synced folder. Word/Excel/Powerpoint/... files you edit in a synced folder save automatically without the need for you to ctrl+s.

If you undo copy that file you will find it in your onedrive history.

The solution to the “undo copy” == “permanent delete” isn’t cloud storage. The solution is simply not to enable that option if the file has been modified. Or at least hide the option behind very explicit warnings.

I’m not saying cloud storage isn’t a good idea as well. But it solves a slightly different problem while creating new ones (needing a Microsoft account, needing an internet connection, files being suitable for cloud storage, etc).
