When you delete a file in Windows, it usually places a Deleted Flag on this file. This delete flag is not removed. This allows others, with the right tools, to recover the name as well as the contents of the file. Securely Erasing uses a more secure way to erase a file. First Tracks Eraser Pro overwrites the file a set number of times with random data. Then it renames the file with a meaningless filename, (e.g. 0001.dat). Finally, Tracks Eraser Pro deletes the file. Therefore, others can not recover the file name or contents. Note: The more times you set to overwrite the file, the more time it will take to erase the tracks. Usually, the default of 3 times is enough. Tracks Eraser Pro implements the Department of Defense clearing and sanitizing standard DOD 5220.
