.tlk

A .tlk file (or a talk table) is a file containing text to be displayed to the player in Neverwinter Nights. Each piece of text in the file is identified by a number called a StringRef. While text can be stored in other locations, a talk table is useful when the text will be translated, as a translator would need to work with only a single file. A talk table is also useful in reducing bandwidth requirements, as a StringRef is usually a much smaller piece of data than the text it refers to.

All game text provided by BioWare comes from the default .tlk,  (or   for some languages when the player character is female). In addition, custom modules can make use of one additional .tlk file. This custom .tlk file must be placed in the game's  directory (not where   is found).
