Listen to jcg...
If you're like me, you'll have more than one 'LiteSTEP' folder anyway.
With the advent of OTS and my manic conversion of all my themes to the standard, I've whittled my dozen or so LS folders [separate complete shells] down to just two...
C:\Litestep\ [a 300 meg configured set of 13 inter-linked themes...that's taken years to 'tweak']
and
C:\Lite-Test\ [my OTS-compliant setup with 17 themes, 13 of which are mine]
It's easy enough to add more to the OTS 'set', or alternatively just add another complete folder for a non-OTS theme.....provided you have ShellON to help you get around..
