I need a secure File Shredder and also an Undeleter (for all file systems would be fine | OPTIMAL: EXT4, ReiserFS, JFS).
Both have to be a GUI , I'm not really a fan of command-line tools.
Btw: I know about the shred command.

And it is possible to edit the KDE/Dolphin right-click menu to add a file-shred command.

thanks in advance

EDIT: i have openSUSE 11.4 with KDE4
