If a file still exists but the contents are wrong, restoring an earlier version is usually safer than scanning the entire drive.

1. Make a copy of the current file

Before restoring anything, duplicate the current file to a different folder. Even a damaged or incomplete copy may contain work you want later.

2. Check the app itself

Look for AutoRecover, version history, recent files, or temporary drafts inside the application that created the file.

3. Check OneDrive version history

If the file is in a OneDrive-synced folder, sign in on the web, select the file, and look for Version history. Restore only after comparing the available dates.

4. Check File History

If File History was configured before the problem occurred, search Windows for "Restore your files with File History," browse to the folder, and inspect earlier versions. Restore to another location first when possible.

5. Check other backup destinations

External-drive backup software, a NAS, and some security suites maintain their own version lists. Do not overwrite the current file until a restored copy opens correctly.

No previous version appears? Version history only works when it was enabled and had already captured the file. It cannot create an older copy after the loss.
