Shred.Files Mobile|生產應用線上App不用買

Do you keep trying to protect your identity? Do you have some files that you wish you never stored on your phone?

If you just delete the files (even using the permanent option), their contents can stay on the disk for a very long time!

NOTE: This app only shreds local Phone files, downloads, photos, videos, etc. It does not shred OneDrive files and online photos. To shred them, you could use the Windows Store app Shredder Advanced by eCodified.

Full functionality during the free, time-limited trial period is provided. Trial expires three days after the first installation.

Shred.Files Mobile by eCodified electronically shreds files and folders by overwriting their contents with random characters (and/or uniform pattern of characters, depending on the selected algorithm). It also renames the files and folders before deletion, so the file / folder names are also effectively overwritten.

The app allows you to leave files in their place after shredding (i.e. not delete them) so you can view their shredded data content, for additional peace of mind.

Several algorithms are provided, similar to these methods and standards:

* eCodified FSA;

* British HMG Infosec Standard 5, Baseline;

* US NIST SP-800-88;

* German BSI / GISA method;

* Russian GOST R 50739-95;

* US DoD Unclassified Computer Hard Drive Disposition;

* US NSA NCSC-TG-025.

Background and Explanation

Deleting files in Windows Phone does not delete contents of the files. If the "safe" delete option is used (the default), files are simply moved to the Recycle Bin, and they can easily be restored, which is SOMETIMES very good :-). NOTE: Other operating systems use the same approach, with both "safe" and permanent delete.

If the permanent delete option is used, file entries are removed from the file system directories (i.e. folders), so the disk space occupied by the "deleted" files can later be used for other files (if and when they are created, or if/when they grow in size). So contents of some "deleted" files can stay intact for a very long time.

Furthermore, the removal of file entries is done by overwriting only the first character of each file's name. So practically, even the file names are still there. Various undelete and data recovery tools rely on this fact. They can read the "removed" file entries, and then try and read the file's contents as well.

One simple solution to this problem is to overwrite file's contents before the file gets "deleted". The only drawback is that overwriting large files can take a long time. That's why eCodified recommends only 1 pass/round of overwriting each file, and it performs very fast algorithm of writing data to files.

Shred.Files Mobile by eCodified has excellent performance characteristics. Progress reporting is provided, and also the ability to cancel longer file shredding procedures.

Full functionality during the free, time-limited period is provided (ads are only displayed during this "trial" period).
