to use knoquerer as a root filemanager do the following:
add a "link to application" on the desktop
name it "root manager" or somethin. then go "Application/command"
konqueror --profile webbrowsing
(or if this doesnt work just try putting konqueror)
then click on advanced options
then select "run as different user"
under Username put: root (or some other username if you wish)
then you can click that icon and add/delete/change root files without actually being root.
