Recover accidentally deleted files even from digital cameras cards, with Restoration
Restoration is a free and portable program you can use to restore files which are deleted even from the recycle bin or deleted while you were holding down the Shift key.
Please note that even if a file seems to have been restored, its contents may not be correct. As is usual with all programs of that kind, Restoration is more effective if you have not let a lot of time pass by after the deletion of the files you need to restore.
You can use Restoration to recover photos from a Flash card and removable drives.
You can search for specific files to restore by using a search term or file extension. Restoration works also with digital camera cards. Please note that the program could and should be more user friendly.
