How to Undelete a File
You can undelete a file if you accidentally deleted it or if you need to otherwise retrieve it. You undelete a file by removing it from the Recycle Bin, which puts it back it in its original location.
Open the Recycle Bin on the desktop.
If the Recycle Bin icon isn’t visible on the desktop, click the far left triangle on the Windows Explorer address bar and choose Recycle Bin from the menu that appears.
Select the file you want to recover.
Click on the file and it’s yours to restore.
Click the Restore This Item button on the toolbar.
The file is removed from Recycle Bin and restored to the folder and disk from which it originated.
Close the Recycle Bin window.
And you’re done!
Windows has no definite time limit on how long you can restore files; they can be available in the Recycle Bin for months or even years. Even so, don’t let the convenience of the Recycle Bin lull you into a false sense of security. Never delete a file unless you’re certain that you want it permanently gone.
