On more recent systems at least (2k, XP) you have the following environment
variables. The values below are typical values; they are not necessarily
like that.

USERNAME=<user>
HOMEDRIVE=C: 
HOMEPATH=\Documents and Settings\<user>
USERPROFILE=C:\Documents and Settings\<user>
ALLUSERSPROFILE=C:\Documents and Settings\All Users
APPDATA=C:\Documents and Settings\<user>\Application Data

APPDATA\<applicationname> is a typical place to put application data.
