by the way ...
since i wanted to delete the supertux 2 games .. to free my apps memory.
there were two files of super tux 2:
SuperTux2
SuperTux2 -DataFiles

when i try to uninstall either of these , it says unable to uninstall the application is needed by other program ..
they both need each other to run so non of these cant be uninstalled from app manager ...
is there anyother way to delete this game ???
from xterminal maybe??
