Whereaminow25: I have downloaded these, and Would like to know the location so I can make a backup of it, so If I get another computer, I can just paste them in without having to redownload them again. Would anyone know the location?

Leroux: If you mean modules downloaded in-game, then you should find them in your Documents\Neverwinter Nights\nwsync folder, encrypted as .sqlite3 databases. No guarantee that moving them will work, but it's worth a try.
