In some rare cases you might also need to put some files in the "override" folder ("Good VS Evil III" is an example), but that's rare and you'll generally be told if that's the case. Some modules require you to download only a MOD file, while some others might require you to download all of the above. MOD files go to "modules" folder - these are the modules themselves TLK files go to "tlk" folder - a talk-table, used for example to add new spell/feat descriptions or modifying existing ones Its just that sometimes with elaborate mods like ADWR shits goes bananas at more complex parts, which needs to be fixed. And it is compatible with vast majority from what i read on other forums. BIC files go to "localvault" folder - these are character files, normally only appearing if the author of the module wants you to use a specific premade character and not your own Enhanced Edition is suppose to be COMPLETELY compatible with ALL mods, thats one of the main draws that Beamdog promised. WAV and BMU files go to "music" folder - mostly soundtrack HAK files go to "hak" folder - these are extra resources, needed by the module but not offered by the game by default Here's what goes where (olnorton's list was not exhaustive):
In all other cases you need to install everything manually.
Sometimes not all the content is packaged with the installer (this should be mentioned on the Vault project page, for example as a required project), in which case you need to install it manually.
In this case you're generally good to go if you just run it and let it install the module and the content. Which weapon should I go for I have a dagger+1 and a shield atm, but now sure what should I aim for later on. Its been really successful so far (lvl4). In general, a module might come packaged in a installer. A dance with rogues build I started a dance with rogues with this build cause I wanted a mix of spellcaster and melee with high charisma.
