Thanks for this query - I had not realised (or forgotten!) that you 
could change the location of this directory (and also $BaseDirectory).

To set this variable (or change its value) go into control panel and 
activate the "System" icon. Select "Advanced" and then "Environment 
Variables" (who said GUI interfaces to this stuff was easy :) ). You can 
add a per-user variable or a system wide variable. Remember to close 
down and restart Mathematica before the changes will come into effect.
