THB filename extension is used for files created by KinuPix, a presentation software that allows users to create rich presentations (in the form of multimedia slides) using various media, sch as photos or interactive graphics. KinuPix offered an unique GUI, very different from those offered by similar applications.

THB files store GUI skins for KinuPix and allowed users to modify program’s interface. KinuPix is considered obsolete and is no longer in use or development.
