Stellar Photo Recovery is a software completely free of charge very useful to recover media files you may have lost.
By simply scanning any local drive, any hard-disk or removable device, this software is able to retrieve videos, images, and sound files with any format that have been digitally (and not physically) removed. Once found, get a preview of all the images, and playback all the videos, before recovering them. In case the scan disk is taking too much time, simply save the results, and resume another time!
Additionally, Photo Recovery is able to create backup images of your hard-drive, in order to recover all your files in case the drive fails. And, as the software name suggests, you can also recover damaged .jpeg pictures.
