 		Directory type. It is used to manage directories and their content (not restricted to the project folder).

+		[DirAccess] can't be instantiated directly. Instead it is created with a static method that takes a path for which it will be opened.
 		[b]Note:[/b] Many resources types are imported (e.g. textures or sound files), and their source asset will not be included in the exported game, as only the imported version is used. Use [ResourceLoader] to access imported resources.

 				This method is potentially slower than [code]decompress[/code], as it may have to re-allocate its output buffer multiple times while decompressing, whereas [code]decompress[/code] knows it's output buffer size from the beginning.
 				GZIP has a maximal compression ratio of 1032:1, meaning it's very possible for a small compressed payload to decompress to a potentially very large output. To guard against this, you may provide a maximum size this function is allowed to allocate in bytes via [param max_output_size]. Passing -1 will allow for unbounded output. If any positive value is passed, and the decompression exceeds that amount in bytes, then an error will be returned.
