# BFWD (Bullfrog World Asset Directory)
The BFWD (Bullfrog WAD) file format contains compressed (or uncompressed) data for rides, textures, UI elements, and more. The data within these files is typically compressed using RefPack (opens new window) (see below). A variant of this file format, known as WAD (FKNL), is used in the PlayStation 2 version of Theme Park World, however is not compatible with DWFB.

# Directories
Occasionally, a file's filename may begin with the name of a directory separated using the \ character. This should
be treated as entering a directory, meaning that file and any further files all belong to that folder.
Here's an example:
| File # | Filename |
|---|---|
| 0 | hello.sam |
| 1 | hello.RSE |
| 2 | textures\hello.wct |
| 3 | hello2.wct |
| 4 | stexture\hello.wct |
| 5 | hello2.wct |
Here, files 0 and 1 both belong to the root of the archive. Files 2 and 3 exist in the textures directory, whereas
files 4 and 5 belong to the stexture directory. Despite file 3 and file 5 both being called hello2.wct, they do not
overlap - they belong in different directories - and therefore they do not conflict.
