 	<description>
 		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.
+		Most of the methods have a static alternative that can be used without creating a [DirAccess]. Static methods only support absolute paths (including [code]res://[/code] and [code]user://[/code]).
+		[codeblock]
+		# Standard
+		var dir = Directory.new()
+		dir.open("user://levels")
+		dir.make_dir("world1")
+		# Static
+		Directory.make_dir_absolute("user://levels/world1")
+		[/codeblock]
 		[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.
 		Here is an example on how to iterate through the files of a directory:
