Deleting a file by mistake is one of those stupid accidents you feel ashamed of explaining to others, like locking yourself out of home or having to pay extra because you forgot your season ticket.
In the case of deleted files however, don't worry because there's a solution. It's called Glary Undelete (yes, the same guys who created Glary Utilities) and it can help you recover any file you've accidentally deleted from your system, even if you have already emptied the Recycle bin.
That said, bear in mind that this kind of software apps must be used with caution, in the sense that they are not magical tools that will recover your files no matter how much time has passed since you delete them. There are other factors that influence the percentage of success in file recovery in addition to time, like drive usage and cluster movement. But if you use Glary Undelete right after the "accident" occurs, chances are you'll be able to recover your files without any problems – and without anybody noticing it.
The program scans the selected drive, among which you can include removable devices, and displays a list with all deleted files along with their recovery status. You can also use filters to refine this search or look for specific files, which comes in really handy as the list is sometimes too long.
Did you just erase a file by accident? Don't worry: Glary Undelete can help you recover it.
