No need to. It would be also a non-functional feature. With current filesystems that employ journaling and what not it is not possible to have a secure file erasure feature in KGPG that would be actually secure.

I know a fair amount about the topic and the above seems overly pessimistic to me about the success of userspace induced wiping.
Lubos, if you're knowledgeable about the topic, would you either respond to my post on this thread from yesterday:
http://article.gmane.org/gmane.linux.suse.general/293911/
Or point me at a discussion on a kde list where they discussed it.
I don't know much about the topic other than http://www.freesoftwaremagazine.com/columns/shred_and_secure_delete_tools_wi... or various other google hits for "kde shred removed".

Lubos, Just so you know that is some well written gobbledygook. No explanation for why shred is incompatible with normal disk journals. No explanation of why they think it works with the other two kinds. As to "successful overwrites", it says the US Gov't requires seven passes. Simply false at least for confidential data. The standard is one pass. You can find that in the NIST Disk Sanitation guidelines. I can get the document name if anyone cares. For secret / top secret I believe the US gov't only allows physical destruction. The drives have to be ground down to the size of sand granules.
