I keep all my downloaded Mods in Zip or RaR format in a separate folder. When I want to use one, I unpack (ok, I'm old - I mean "Extract") direct into the MODS folder in the game by clicking on the Zip or RaR file, highlighting the folder I want to install, then selecting the 'Extract To" folder, which is usually the second choice in the selection window. Then I click "Extract" and away it goes. One thing I've noticed is that sometimes it duplicates the extract, putting one set in the MODS folder and another in the Root folder. JSGME ignores the one in the Root folder, so I just delete it after checking it is actually in the Root folder. Hope this answers your question. Good Hunting!
