There are two types of language files that are used to translate mods. The first is the techtree language file, and is located in techtree_name/lang/ and will be named techtree_name_language.lng. For example, in Magitech, it would be named magitech/lang/magitech_en.lng (en is the short code for English, see Language codes below for a full list of the language codes). This file would contain the strings for the resources, faction names, attack type names, and armor type names. Both of these will be explained in detail later on this page (see Techtree language file and Faction language file).
