First, check the Recycle bin or OneDrive trash for the missing files. If you find the files, restore them.

Next, try looking for the missing file in all locations in OneDrive. If this doesn’t work, you can search for the file type in the search bar.

If the file is still not found, then try the following steps:

1. Check if the file exists in other computers associated with the same Microsoft account.
2. Restart your computer and try again.
3. Update the OneDrive app to make sure you’re running the latest version.
4. Uninstall the app and reinstall it. Make sure to sign in with the same Microsoft account.
