[USAGE]
The install to mod folder is linked to the
final DLCList.xml ; therefore if install to
mod folder is ON then DLCList.xml will
be generated from mod folder , and vice versa.
To change this after installations , just toggle
the switch before pressing finish , values are not
pre-read.


[NEWS]

& zip library
