For those that want to try this, and I make no guarantee as to it's efficacy.
Here's what i did to add a right click secure delete action for files and folders..
Make sure you have bcwipe installed from the repo. Create a wipefiles.desktop file and paste this code into it.
[Desktop Action delete]
Exec=bcwipe -rf -mt
As root (obviously) put it in /usr/share/kde4/services/ServiceMenus
Log out and back in. There should now be a secure Delete File option in the Actions menu when you right click
on a file or folder. I used the bleachbit icon because the new one is really cool but you can use any icon you like.
If anyone finds this doesn't work (how can you tell?) or has an improvement let me know.
