rowanreader Hey, sorry that happened. We actually already have a pretty detailed guide on LibreOffice document recovery here, definitely worth checking out.
From the sound of it, AutoSave wasn’t active in your settings, which is why your changes didn’t get saved. If you want autosaving going forward, go to Tools - Options - Load/Save - General and enable “Save AutoRecovery information every X minutes”.
Since you’ve already checked backup and temp folders, you’ve covered most of the basics. Another thing you can still try: if File History was enabled in Windows, right-click the file or the folder it was in, go to Properties > Previous Versions, and see if anything shows up. Maybe Windows saved versions you can restore from.
And if there’s a chance the file was actually deleted, your best bet is to use a data recovery tool like Disk Drill, R-Studio, or Recoverit to scan the same drive. Just be sure to recover to a different location so you don’t accidentally overwrite anything.
Hope something turns up.
