How to change the default directory for keeping custom content?

[VoodooMaster]

Well if you installed UT3 in a diferent HDD you can use the -nohomedir command on the UT3 shortcut and put the custom content in UT3 instalation folder.

All the custom maps/mods are by default stored in the "....\My Documents\My Games" folder. Is there a way to change this to some other directory since my home directory is running out of space. I would like all the custom maps to be in a single place but not in the C drive.
