Recover Everything: PhotoData is a free photo recovery application that can restore photos and documents deleted by mistake or due to system damage. The application works by scanning all the photos and files on your device, looking for signs of corruption or other damage, and then fixing those issues. If it finds any issues, it will notify you so you can take further steps to recover the photos.

If you want to use the app, you first need to make sure that you have a SD card on your device. If you don’t have an SD card, you can choose to use the internal memory of your device.
