If you've deleted file(s) and want to recover them, you may use the Restore utility to restore them.
1. Right click on the folder that contained your file(s) and select "Restore previous versions"
2. Select the folder version with the date/time that you prefer and click Restore... That will restore the entire folder.
If you'd prefer to restore a single file, double click a folder, and you'll have access to its contents. Open or copy files as needed from there.
3. Click "Restore" one more time, then after some processing, your files will be restored.
