Yeah, I don't even remember doing it, but I've got a Text file with clearly a previous version of what the info I'd written in it, and I can't find the updated latest file anymore. Doing lots of handling of such files currently, I must've copy-pasted an old version on it by mistake along with other copy-pastes. I know there are programs to retrieve deleted files, but is there a way to just get back a previous version of a small native file like a TextEdit file ? A kind of 'Undo' thing...or a software perhaps. I don't use the Time Machine thing on my mac.
