Thanks for the info,

Tried
LC_ALL=en sudo konqueror --profile filemanagement

Returned the following errors;
Error: "/var/tmp/kdecache-knoppix" is owned by uid 1000 instead of uid 0.
Link points to "/var/tmp/kdecache-root"
Error: "/tmp/kde-knoppix" is owned by uid 1000 instead of uid 0.
Link points to "/tmp/kde-root"
Error: "/tmp/ksocket-knoppix" is owned by uid 1000 instead of uid 0.
Link points to "/tmp/ksocket-root"
Error: "/var/tmp/kdecache-knoppix" is owned by uid 1000 instead of uid 0.
Link points to "/var/tmp/kdecache-root"

...and File Manager opened without Root privileges

Rather than fight with the permissions etc,

then tried LC_ALL=en konqueror --profile filemanagement after a su in Konsole.

This seems to load File Manger - Super User Mode in English.

There were a lot of error messages (a long list - I'll post if anyone requests),
but seems I can now move, rename, delete, etc.in File Manager as Root in English.
