Learn how to delete your file properly with jDelete.

1-pass random algorithm

This algorithm overwrite the file data with in a single random pass, writing randomly 0 or 1 over each bit of the original file.

3-passes DoD 5220.22-M (E) method

This 3-passes algorithm made by the US Department of Defense performs 3 successive passes over the file.

• A pass that overwrites each byte of the original file with 11111111
• A pass that overwrites each byte of the original file with 00000000
• A random pass

7-passes DoD 5220.22-M (ECE) method

• A pass that overwrites each byte of the original file with 10101010
• A random pass
• A pass that overwrites each byte of the original file with 01010101

Gutmann method

This method performs a 35-passes algorithm. Files are overwrited 35 times with different series of bytes... For more information check the page about Gutmann method on wikipedia.
