TweakUI lets me change my "My Documents" folder to wherever. The problem is, some programs stick crap in there without asking. I'm looking right now, and Battlefield 2, for instance, has created itself a folder and stashed a few files.
If I switch "My Documents" to some other folder far, far away, will this screw up existing programs? More importantly, will new programs I install start stashing their crap in the new folder, or will they still stick it in "C:\Documents and Settings\Danny\My Documents" where they go by default right now?
