Uninstall and reinstall game

So if I understand correctly, I can transfer the zip files to my desktop from my external drive.  I can extract those zip files so I have the folders I started with.  Then, instead of dragging that folder back into the Mods folder, I create a new subfolder in my Mods folder ("Accessories" or something like that) and just drag all the individual files from the old folder to the new one, and then delete the empty folder from my desktop.
