News for November 2018
Time for another great update to DiskDigger for Android! Over the last few months, more and more users have requested the ability to delete the photos and other files that are found by DiskDigger, so that they can no longer be recovered by anyone else. This update makes a significant step in that direction:
After completing the scan of your device, the app now offers you the ability to enter Cleanup Mode, accessible by tapping the "Clean up" button, where you can select the items you'd like to delete, and remove them permanently.
This feature is still very new and a bit experimental, so there are a few points to keep in mind when using it:
- Cleanup Mode is currently available only in the Basic Scan. Making it available in the Full (rooted) scan is quite a bit more complex, and will be available in a future version.
- The Cleanup screen is divided into two tabs: "Thumbnail caches" and "Photos." This is because a thumbnail cache (a file that contains multiple thumbnails) must be deleted as a whole, which would delete all the thumbnails contained in it. Therefore the app allows you to examine these thumbnail caches, as well as individual photos, and select which ones you want to delete.
- Since the deletion is done at the filesystem level, the contents of the deleted files are not physically wiped from the device's memory, and may still be recoverable if the device is rooted. In fact, even physical wiping of the files' contents is unreliable with flash memory, which employs wear-leveling that might redirect the overwritten data to a different physical location.
In the near future, look for further enhancements and updates to the Cleanup feature. And as always, DiskDigger for Android and DiskDigger for Windows are still the best choice for your data recovery needs.
