# Paths

The Paths class holds some new functions and variables that may be useful for creating mods:

• getPath(path, library) allows you to return a full path according to its library, if there is one.
• fileExists(path, library) allows you to check if a certain file exists.
• clearMemory() allows you to manually wipe the memory.
• readDir(directory, type, removeType, library) allows you to read the contents of a certain directory.
• preloadPlayStuff() allows you to preload PlayState related assets, such as the countdown and Hitsounds.
• preloadGraphic(key, library) and preloadSound(key, library) allow you to preload a certain image or sound.

# Libraries

One of FNF: Doido Engine's latest features is library support, similar to Psych Engine. This allows you to create folders inside of the assets/ folder to better organize your own files. Simply make your own folder in assets/, create the necessary Paths (Ex. images, sounds) and then use the library on any supported Paths functions.
