If you Windows, take note windows have "system restore" and "previous version" as backup method which usually enabled by default. Did you check both of them? But even if there's no backup, sometimes it's possible to recover file which updated/modified. I would recommend you to make raw copy of your drive (with tool such as HDD Raw Copy[1]), so later you could use recovery tools (such as PhotoRec[2] or Recuva[3]) without worry the data overwritten since you keep using it.
