+		Type used to handle the filesystem.
+	</brief_description>
+	<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.
+		[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:
+		[codeblocks]
+		[gdscript]
+		func dir_contents(path):
+		    var dir = DirAccess.open(path)
+		    if dir:
+		        dir.list_dir_begin()
+		        var file_name = dir.get_next()
+		        while file_name != "":
+		            if dir.current_is_dir():
+		                print("Found directory: " + file_name)
+		            else:
+		                print("Found file: " + file_name)
+		            file_name = dir.get_next()
+		    else:
+		        print("An error occurred when trying to access the path.")
+		[/gdscript]
+		[csharp]
+		public void DirContents(string path)
+		{
+		    var dir = DirAccess.Open(path);
+		    if (dir != null)
+		    {
+		        dir.ListDirBegin();
+		        string fileName = dir.GetNext();
+		        while (fileName != "")
+		        {
+		            if (dir.CurrentIsDir())
+		            {
+		                GD.Print("Found directory: " + fileName);
+		            }
+		            else
+		            {
+		                GD.Print("Found file: " + fileName);
+		            }
+		            fileName = dir.GetNext();
+		        }
+		    }
+		    else
+		    {
+		        GD.Print("An error occurred when trying to access the path.");
+		    }
+		}
+		[/csharp]

+		<method name="change_dir">
+			<return type="int" enum="Error" />
+			<param index="0" name="todir" type="String" />
+			<description>
+				Changes the currently opened directory to the one passed as an argument. The argument can be relative to the current directory (e.g. [code]newdir[/code] or [code]../newdir[/code]), or an absolute path (e.g. [code]/tmp/newdir[/code] or [code]res://somedir/newdir[/code]).

+			<param index="2" name="chmod_flags" type="int" default="-1" />
+			<description>
+				Copies the [param from] file to the [param to] destination. Both arguments should be paths to files, either relative or absolute. If the destination file exists and is not access-protected, it will be overwritten.
+				If [param chmod_flags] is different than [code]-1[/code], the unix permissions for the destination path will be set to the provided value, if available on the current operating system.
+				Returns one of the [enum Error] code constants ([code]OK[/code] on success).
+			</description>
+		</method>
+		<method name="current_is_dir" qualifiers="const">
+			<return type="bool" />
+			<description>
+				Returns whether the current item processed with the last [method get_next] call is a directory ([code].[/code] and [code]..[/code] are considered directories).
+			</description>
+		</method>
+		<method name="dir_exists">
+			<return type="bool" />
+			<param index="0" name="path" type="String" />
+			<description>
+				Returns whether the target directory exists. The argument can be relative to the current directory, or an absolute path.
+				If the [DirAccess] is not open, the path is relative to [code]res://[/code].
+			</description>
+		</method>
+		<method name="file_exists">
+			<return type="bool" />
+			<param index="0" name="path" type="String" />
+			<description>
+				Returns whether the target file exists. The argument can be relative to the current directory, or an absolute path.
+				If the [DirAccess] is not open, the path is relative to [code]res://[/code].
+			</description>
+		</method>
+		<method name="get_current_dir" qualifiers="const">
+			<return type="String" />
+			<param index="0" name="include_drive" type="bool" default="true" />
+			<description>
+				Returns the absolute path to the currently opened directory (e.g. [code]res://folder[/code] or [code]C:\tmp\folder[/code]).
+			</description>
+		</method>
+		<method name="get_current_drive">
+			<return type="int" />
+			<description>
+				Returns the currently opened directory's drive index. See [method get_drive] to convert returned index to the name of the drive.
+			</description>
+		</method>
+		<method name="get_directories">
+			<return type="PackedStringArray" />
+			<description>
+				Returns a [PackedStringArray] containing filenames of the directory contents, excluding files. The array is sorted alphabetically.
+				Affected by [member include_hidden] and [member include_navigational].
+			</description>
+		</method>
+		<method name="get_drive">
+			<return type="String" />
+			<param index="0" name="idx" type="int" />
+			<description>
+				On Windows, returns the name of the drive (partition) passed as an argument (e.g. [code]C:[/code]).
+				On macOS, returns the path to the mounted volume passed as an argument.
+				On Linux, returns the path to the mounted volume or GTK 3 bookmark passed as an argument.
+				On other platforms, or if the requested drive does not exist, the method returns an empty String.
+			</description>
+		</method>
+		<method name="get_drive_count">
+			<return type="int" />
+			<description>
+				On Windows, returns the number of drives (partitions) mounted on the current filesystem.
+				On macOS, returns the number of mounted volumes.
+				On Linux, returns the number of mounted volumes and GTK 3 bookmarks.
+				On other platforms, the method returns 0.
+			</description>
+		</method>
+		<method name="get_files">
+			<return type="PackedStringArray" />
+			<description>
+				Returns a [PackedStringArray] containing filenames of the directory contents, excluding directories. The array is sorted alphabetically.
+				Affected by [member include_hidden].
+			</description>
+		</method>
+		<method name="get_next">
+			<return type="String" />
+			<description>
+				Returns the next element (file or directory) in the current directory.
+				The name of the file or directory is returned (and not its full path). Once the stream has been fully processed, the method returns an empty [String] and closes the stream automatically (i.e. [method list_dir_end] would not be mandatory in such a case).
+			</description>
+		</method>
+		<method name="get_open_error" qualifiers="static">
+			<return type="int" enum="Error" />
+			<description>
+				Returns the result of the last [method open] call in the current thread.
+			</description>
+		</method>
+		<method name="get_space_left">
+			<return type="int" />
+			<description>
+				On UNIX desktop systems, returns the available space on the current directory's disk. On other platforms, this information is not available and the method returns 0 or -1.
+			</description>
+		</method>
+		<method name="list_dir_begin">
+			<return type="int" enum="Error" />
+			<description>
+				Initializes the stream used to list all files and directories using the [method get_next] function, closing the currently opened stream if needed. Once the stream has been processed, it should typically be closed with [method list_dir_end].
+				Affected by [member include_hidden] and [member include_navigational].
+				[b]Note:[/b] The order of files and directories returned by this method is not deterministic, and can vary between operating systems. If you want a list of all files or folders sorted alphabetically, use [method get_files] or [method get_directories].
+			</description>
+		</method>
+		<method name="list_dir_end">
+			<return type="void" />
+			<description>
+				Closes the current stream opened with [method list_dir_begin] (whether it has been fully processed with [method get_next] does not matter).
+			</description>
+		</method>
+		<method name="make_dir">
+			<return type="int" enum="Error" />
+			<param index="0" name="path" type="String" />
+			<description>
+				Creates a directory. The argument can be relative to the current directory, or an absolute path. The target directory should be placed in an already existing directory (to create the full path recursively, see [method make_dir_recursive]).
+				Returns one of the [enum Error] code constants ([code]OK[/code] on success).
+			</description>
+		</method>
+		<method name="make_dir_recursive">
+			<return type="int" enum="Error" />
+			<param index="0" name="path" type="String" />

+				Creates a target directory and all necessary intermediate directories in its path, by calling [method make_dir] recursively. The argument can be relative to the current directory, or an absolute path.
+				Returns one of the [enum Error] code constants ([code]OK[/code] on success).
+			</description>
+		</method>
+		<method name="open" qualifiers="static">
+			<return type="DirAccess" />
+			<param index="0" name="path" type="String" />
+			<description>
+				Creates a new [DirAccess] object and opens an existing directory of the filesystem. The [param path] argument can be within the project tree ([code]res://folder[/code]), the user directory ([code]user://folder[/code]) or an absolute path of the user filesystem (e.g. [code]/tmp/folder[/code] or [code]C:\tmp\folder[/code]).
+				Returns [code]null[/code] if opening the directory failed. You can use [method get_open_error] to check the error that ocurred.
+			</description>
+		</method>
+		<method name="remove">
+			<return type="int" enum="Error" />
+			<param index="0" name="path" type="String" />
+			<description>
+				Permanently deletes the target file or an empty directory. The argument can be relative to the current directory, or an absolute path. If the target directory is not empty, the operation will fail.
+				If you don't want to delete the file/directory permanently, use [method OS.move_to_trash] instead.
+				Returns one of the [enum Error] code constants ([code]OK[/code] on success).
+			</description>
+		</method>
+		<method name="rename">
+			<return type="int" enum="Error" />
+			<param index="0" name="from" type="String" />
+			<param index="1" name="to" type="String" />
+			<description>
+				Renames (move) the [param from] file or directory to the [param to] destination. Both arguments should be paths to files or directories, either relative or absolute. If the destination file or directory exists and is not access-protected, it will be overwritten.
+				Returns one of the [enum Error] code constants ([code]OK[/code] on success).
