What RAMworks has done is bad in that the Poser 13 content is always overwritten with each new install of the program.  So that if you have your LeFemme files located there and with the next update Poser decides to include LaFemme as part of the basic content then at every install your more updated version will be overwritten with the basic version.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
