- `LIBC_FILEIO_ENABLED` wasn't defined anywhere, even in _other platforms_. - `NO_NETWORK` is also never defined. It probably isn't enough anyway to disable network APIs in the current codebase. - `UNIX_SOCKET_UNAVAILABLE` is never defined in this code but used by some other platforms, clarify that. - `NO_STATVFS` can be removed as Android supports it since API level 19, which is our current min SDK level. It's also only used for `DirAccessUnix::get_space_left()` which is anyway overridden by `DirAccessJAndroid::get_space_left()` so it shouldn't make a difference. * Fixed documentation for `DirAccess.get_space_left()`. - `NO_FCNTL` is likely also a remnant of early Android days, in current NDK r23 it seems to be available. Also cleaned up unused `fcntl.h` includes. - `NO_ALLOCA` is never defined, and we use alloca in many places now.

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.
|
|
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 = DirAccess.open("user://levels")
|
|
dir.make_dir("world1")
|
|
# Static
|
|
DirAccess.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:
|
|
[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)
|
|
{
|
|
using 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.");
|
|
}
|
|
}

<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).

<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>
|

<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 occurred.

|
|
<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.

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.
