Deleted files on a computer may seem like a lost cause, but there are methods and other programs you can use to recover those lost files. Recovering lost files only takes a few minutes if the files haven't been overwritten and can save you lots of stress.
Recovering Deleted Files in Windows Operating Systems
Open the "Recycle Bin." Try to locate the deleted file you wish to recover. Right click the item you wish to restore and click "Restore." If you've permanently deleted all of the files in the "Recycle Bin," move on to step two.
