Is there anyway of completely installing Thunberbird on a different drive and not have any stuff including symlinks in the users home directory? Installing Thunderbird on a different drive/location is documented and straight forward but it insists on putting stuff in the users home directory ''C:\Users\<user>\AppData\'' . The problem can be fixed by using copying everything Thunderbird related in the C:\Users\<user>\AppData\ to the other drive and use symlinks from C:\Users\<user>\AppData\ directory to its new location. Thunderbird seems to be ok with symlinks.
