Recovering Unsaved and Overwritten Office Files
Losing a document almost never means the work is gone — it means you are looking in the wrong place. Word and Excel both keep automatic recovery copies in locations that are not obvious, OneDrive quietly keeps a version history for every file it syncs, and Windows itself keeps previous versions when File History is on. These guides go through those recovery paths in the order most likely to find your file, and then show you the settings that make the next near-miss a non-event.

Office questions
Can I recover a Word document I never saved at all?
Often yes. Word writes AutoRecover snapshots every ten minutes by default, and keeps unsaved drafts for four days. Open Word, go to File, Open, then Recover Unsaved Documents at the bottom of the recent files list.
Can I get back the version of a file before I saved over it?
If the file is in OneDrive or SharePoint, yes — right-click it and choose Version history. If it is on a local drive, you need Windows File History or a restore point to have been enabled beforehand.
Does AutoSave protect me from mistakes?
Only partly. AutoSave saves your changes continuously, including the ones you regret, so it is not a safety net on its own. Version history is what lets you undo a bad edit, and it only exists for files stored in OneDrive or SharePoint.
