Download Disk Drill for Windows and install it on your machine.
Select the drive or partition that contained the YouTube videos that have been deleted.
Click the “Recover” button to initiate the scanning procedure and let Disk Drill search for your videos. You can filter on filetype and narrow your search to the videos in question. The application will return a list of the files that can be recovered.
Select the YouTube videos that you want to recover and a new location in which to store them. Stay away from their original location to avoid file corruption.
Click the “Recover” button a second time and your selected files will be restored to your chosen location.
