Mireth Technology has released ShredIt X 5.2, the latest version of its Mac OS X utility that securely deletes files, folders and disk free space. “Throwing a file in the trash does not remove the file contents from the hard disk — it just removes the file name from the directory, leaving the data intact and vulnerable. What you threw away can be recovered by anyone with access to your computer.” Version 5.2 brings a shred “free space” feature that allows you to shred files which have been previously deleted. The free update also adds a Department of Defense 5220 standard compliance option. Shredit X sells for US$19.95.
