CST files contain external casts, which are fully delinked from the target movie. Internal casts, on the other hand, cannot be delinked from the movie and may only be used for the movie they are linked to.

Since Adobe Director has been replaced by Adobe Flash, CST files are not commonly used anymore.

A CST file may also be a script used by a visual novel developed using the CatSystem2 game engine. It contains data used to load and play a visual novel scene. This includes metadata and commands used to display text, play audio, and show sprites and animations.

CatSystem2 is a visual novel game engine developed by Windmill. It is the successor to the original CatSystem, which was developed by Cat Works Team. Various developers use CatSystem2 to create visual novels. For example, Frontwing's Grisaia series and Azarashi Software's Amakano series both use CatSystem2.

Games developed using CatSystem2 include scripts saved as CST files. Each script contains commands used to load and play a particular scene. For this reason, you may also see CST files referred to as CatSystem2 scenes or CST scenes.

You can open a CST file with CatSceneEditor (multiplatform) or TriggersTools.CatSystem2 (multiplatform). Doing so will allow you to edit the data the CST file contains.
