I don't know.
Let me scratch a claw at the manual.

I don't think it does. But I think if you use
the PATH command and add folders too..they will be searched in there along with the main work folder.

here is some from the online manual.

PATH "dirname";
All files belonging to the application - bitmaps, sounds, entities etc. - will be first searched for in the work folder and then in the folder given here.
Remarks:
Backslashes ("\") have to be given in C notation as double backslashes (like "C:\\games").
Paths will be searched in the given sequence. Paths are relative to the current work folder. In order to be able to copy your project to different locations, use relative paths for all files belonging to your project, and absolute paths for all files that are on an absolute location on your hard disk (like template scripts).
A7 If the path begins with "%EXE_DIR%", it's a subfolder of the program folder (like "%EXE_DIR%\\template_6\\models"). Apart from that, do not use special characters or spaces in your folder names.
