Ok. So I finally have installed the Mod folder on the default location : partition C. What a big s#*! ! GRRRR ! :laugh: During the installation of NMM, you can choose the location of several repertories (and the location of the Mod folder too) and so, yes, you think you can put all that stuff on the drive you want but in fact, no. If you change the default locations, a warning message allways say something like : if you do that, baf ! explosion ! So voila, you have the choice but please, don't change anything. Hahaha ! Anyway, your help was great. Friendly thanks from a guy who speak English like a French cow. :thumbsup: :wink:
