Beware: The contents of a file are not cleared when normallydeleting a file. Forensic tools and file recovery tools can be usedto recover files which have not been securely deleted. FShred is asimple, handy app that makes deleted files on your internal storageunrecoverable by overwriting all available space with random data.This means recoverable data from deleted files, such as images,videos, databases, is replaced with useless bytes supplied by arandom generator. This app has been tested with multiple filerecovery applications such as GT File Recovery and no deleted filescould be recovered. If you are still able to recover files afterrunning FShred, please try and run it again. Please Note: This appdoes not delete ANY existing files when 'shredding' your internalstorage. Your existing data will be unchanged throughout and afterthe process. This application contains no advertisements or in apppurchases. It is completely free and convenient to use and willremain this way forever. Additional Features: • The app acts as ashare target so you can securely delete files from your favouritefile manager! • You can now choose which storage device you wouldlike to shred the free space of. • Tested with multiplerecovery/forensic tools.

No really, this game is impossible. The developer cannotevencomplete it. Can you? This is a beta release, with only 10levels.

The contents of a file are not cleared when normally deletingafile. Forensic tools and file recovery tools can be used torecoverfiles which have not been securely deleted. File Shredder isasimple, handy app that makes deleted files on your internalstorageunrecoverable by overwriting all available space with zerosorrandom data (see modes below). This means recoverable datafromdeleted files such as images, videos, databases, is replacedwithuseless bytes. A large file is created on the selectedstoragedevice which will fill remaining space on the device. Thisapp doesNOT delete any existing files. Any storage device that isvisibleto Android's Storage Access Framework can be shredded. Youcanchoose between different shredding modes: - Zeros - overwritesfreespace with zeros (fastest) - Random - overwrites free spacewithrandom data - Secure Random - overwrites free spacewithcryptographically secure random data (slowest) File Shreddercanalso shred individual files and directories. Thisinvolvesoverwriting the files with data from the chosen mode,overwritingthe file's name with a random name (longer than theoriginal name),and finally deleting the file normally. FileShredder has beentested with a handful of file recovery appsavailable for Android(including root ones that directly read fromblock storage devices)and all were unable to recover any deletedfiles after using thisapp. NOTE: flash memory used in phones haslimited durability - itis recommended that File Shredder is notused as a habit, butrather only when it's needed. Additionally,flash memory usuallycomes with 'wear levelling' features, whichmeans that writing tothe same 'file' twice does not necessarilymean that the samephysical location on the flash memory will bewritten to. Thismeans it is possible (but rather unlikely) thatvery sophisticatedrecovery methods that look at wear levellingblocks of the device'sflash memory could pick up fragments ofdeleted files. Running FileShredder multiple times may reduce thischance (although it isquite low to begin with).
