DiskDigger can recover and recover lost photos and images from memory card or internal memory. No need to root! * Whether you accidentally delete a photo or reformat your memory card, DiskDiggers’ powerful data recovery feature will help you find and recover your lost images.
You can upload the restored file directly to Google Drive, Dropbox, or send it by email. The application can also save the file to another local folder on the device.
If the device is not rooted, the application will search the cache and thumbnails and perform a “restricted” scan of deleted photos. * If the device is rooted, the application searches the entire memory of the device for traces of photos and videos.
When the scan is complete, tap the Clean button to permanently remove the items you no longer need (currently an experimental feature and only available for basic scans).
You can also use the Free Space option to remove the remaining free space on your device and make the deleted files unrecoverable.
