Actor contains files defining actors.
ActorInfo.product.sbyml (found in the Actor directory) is a Yaz0-compressed BYML file which contains general information about all actors in the game. It is used when constructing actors, and also used to access actor data efficiently when loading the full actor pack is unnecessary (e.g. on menu screens). Therefore, in order to add new actors, or to change items' parameters on menu screens, this file must be edited.
ActorInfo is a machine generated file. It is not meant to be edited directly; much of the information it includes are either automatically generated or copied from ActorParam files (which can be found in the game content) and other source-only files.
Contains archives defining parameters for actors.
Directories containing dummy ActorParam configuration files containing default values. They are used as a fallback when loading actors. The "ActorLink" directory is not present here.
