com.starry.storage_shredderStorageShredder Overwrite deleted files so they stay deleted
Deleting files or running a factory reset can still leave data traces on your phone, and recovery tools can sometimes bring them back.
StorageShredder fills your remaining free space with dummy data, writing over the spots where your deleted files used to sit. Once overwritten, that data is much harder for recovery tools to find.
Use it before selling or handing down your phone, or whenever you want sensitive photos and documents gone for good.

SCREENSHOTS
FEATURES
Features
Erase traces after a format
Overwrites data remnants that can linger in storage even after a factory reset or format. Reset your phone first, then run this pass before selling it.
Just the folders you pick
Instead of the entire device, wipe the traces of deleted files inside a folder you select, such as Downloads.
More passes, harder recovery
Repeating the overwrite lowers the odds of recovery even further. Total Operations tracks how many passes you have completed.
HOW TO USE

- 01

FAQ
FAQ
Is StorageShredder free?
Yes. It is free with ads, and there are no in-app purchases.
Will it delete the photos and files I still have?
No. It only overwrites empty space, so the files you have now stay as they are. Only traces of files you have already deleted are affected.
How long does it take?
Depending on your phone and how much free space you have, it can take tens of minutes or longer. Keep the app open and the screen on while it runs.
Can I use other apps while it runs?
Because it works by filling free space, your storage will be nearly full during the job. Leave tasks that need disk space, like taking photos or updating apps, until it is done.
