DiskDigger is a data recovery app that can retrieve lost photos, images, and videos from internal and external memory. It can recover files that were accidentally deleted or lost due to reformatting. The app has powerful data recovery features that can find lost pictures and videos and restore them. Users can upload recovered files to Google Drive, Dropbox, or send them via email. The app also allows users to save files to a different local folder on their device.

The app requires the "Access all files" permission on the device to search all locations for lost and recoverable photos. If the device is not rooted, the app will perform a "limited" scan by searching the cache and thumbnails. If the device is rooted, the app will search all of the device's memory for any trace of photos and videos.

After the scan is complete, users can tap the "Clean up" button to permanently delete any items they no longer need. The app also has an experimental feature called "Wipe free space" that erases the remaining free space on the device, making any deleted files unrecoverable.

For complete instructions, users can visit the DiskDigger website. If users need to recover more types of files besides photos and videos, they can try DiskDigger Pro.

Overall, DiskDigger is a useful app for anyone who has lost photos, images, or videos on their device. It has powerful data recovery features and allows users to upload recovered files to cloud storage or save them to a different local folder.
