FileAccess
==========

**Inherits:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Provides methods for file reading and writing operations.

.. rst-class:: classref-introduction-group

Description
-----------

This class can be used to permanently store data in the user device's file system and to read from it. This is useful for storing game save data or player configuration files.

\ **Example:** How to write and read from a file. The file named ``"save_game.dat"`` will be stored in the user data folder, as specified in the :doc:`Data paths <../tutorials/io/data_paths>` documentation:


.. tabs::

 .. code-tab:: gdscript

    func save_to_file(content):
        var file = FileAccess.open("user://save_game.dat", FileAccess.WRITE)
        file.store_string(content)

    func load_from_file():
        var file = FileAccess.open("user://save_game.dat", FileAccess.READ)
        var content = file.get_as_text()
        return content

 .. code-tab:: csharp

    public void SaveToFile(string content)
    {
        using var file = FileAccess.Open("user://save_game.dat", FileAccess.ModeFlags.Write);
        file.StoreString(content);
    }

    public string LoadFromFile()
    {
        using var file = FileAccess.Open("user://save_game.dat", FileAccess.ModeFlags.Read);
        string content = file.GetAsText();
        return content;
    }



A **FileAccess** instance has its own file cursor, which is the position in bytes in the file where the next read/write operation will occur. Functions such as :ref:`get_8()<class_FileAccess_method_get_8>`, :ref:`get_16()<class_FileAccess_method_get_16>`, :ref:`store_8()<class_FileAccess_method_store_8>`, and :ref:`store_16()<class_FileAccess_method_store_16>` will move the file cursor forward by the number of bytes read/written. The file cursor can be moved to a specific position using :ref:`seek()<class_FileAccess_method_seek>` or :ref:`seek_end()<class_FileAccess_method_seek_end>`, and its position can be retrieved using :ref:`get_position()<class_FileAccess_method_get_position>`.

A **FileAccess** instance will close its file when the instance is freed. Since it inherits :ref:`RefCounted<class_RefCounted>`, this happens automatically when it is no longer in use. :ref:`close()<class_FileAccess_method_close>` can be called to close it earlier. In C#, the reference must be disposed manually, which can be done with the ``using`` statement or by calling the ``Dispose`` method directly.

\ **Note:** To access project resources once exported, it is recommended to use :ref:`ResourceLoader<class_ResourceLoader>` instead of **FileAccess**, as some files are converted to engine-specific formats and their original source files might not be present in the exported PCK package. If using **FileAccess**, make sure the file is included in the export by changing its import mode to **Keep File (exported as is)** in the Import dock, or, for files where this option is not available, change the non-resource export filter in the Export dialog to include the file's extension (e.g. ``*.txt``).

\ **Note:** Files are automatically closed only if the process exits "normally" (such as by clicking the window manager's close button or pressing :kbd:`Alt + F4`). If you stop the project execution by pressing :kbd:`F8` while the project is running, the file won't be closed as the game process will be killed. You can work around this by calling :ref:`flush()<class_FileAccess_method_flush>` at regular intervals.

Property Descriptions
---------------------

.. _class_FileAccess_property_big_endian:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **big_endian** :ref:`🔗<class_FileAccess_property_big_endian>`

.. rst-class:: classref-property-setget

- |void| **set_big_endian**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **is_big_endian**\ (\ )

If ``true``, the file is read with big-endian `endianness <https://en.wikipedia.org/wiki/Endianness>`__. If ``false``, the file is read with little-endian endianness. If in doubt, leave this to ``false`` as most files are written with little-endian endianness.

\ **Note:** This is always reset to system endianness, which is little-endian on all supported platforms, whenever you open the file. Therefore, you must set :ref:`big_endian<class_FileAccess_property_big_endian>` *after* opening the file, not before.

Method Descriptions
-------------------

.. _class_FileAccess_method_close:

.. rst-class:: classref-method

|void| **close**\ (\ ) :ref:`🔗<class_FileAccess_method_close>`

Closes the currently opened file and prevents subsequent read/write operations. Use :ref:`flush()<class_FileAccess_method_flush>` to persist the data to disk without closing the file.

\ **Note:** **FileAccess** will automatically close when it's freed, which happens when it goes out of scope or when it gets assigned with ``null``. In C# the reference must be disposed after we are done using it, this can be done with the ``using`` statement or calling the ``Dispose`` method directly.

.. rst-class:: classref-item-separator

----

.. _class_FileAccess_method_create_temp:

.. rst-class:: classref-method

:ref:`FileAccess<class_FileAccess>` **create_temp**\ (\ mode_flags\: :ref:`int<class_int>`, prefix\: :ref:`String<class_String>` = "", extension\: :ref:`String<class_String>` = "", keep\: :ref:`bool<class_bool>` = false\ ) |static| :ref:`🔗<class_FileAccess_method_create_temp>`

Creates a temporary file. This file will be freed when the returned **FileAccess** is freed.

If ``prefix`` is not empty, it will be prefixed to the file name, separated by a ``-``.

If ``extension`` is not empty, it will be appended to the temporary file name.

If ``keep`` is ``true``, the file is not deleted when the returned **FileAccess** is freed.

Returns ``null`` if opening the file failed. You can use :ref:`get_open_error()<class_FileAccess_method_get_open_error>` to check the error that occurred.

.. rst-class:: classref-item-separator

----

.. _class_FileAccess_method_eof_reached:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **eof_reached**\ (\ ) |const| :ref:`🔗<class_FileAccess_method_eof_reached>`

Returns ``true`` if the file cursor has already read past the end of the file.

\ **Note:** ``eof_reached() == false`` cannot be used to check whether there is more data available. To loop while there is more data available, use:


.. tabs::

 .. code-tab:: gdscript

    while file.get_position() < file.get_length():
        # Read data

 .. code-tab:: csharp

    while (file.GetPosition() < file.GetLength())
    {
        // Read data
    }



.. rst-class:: classref-item-separator

----

.. _class_FileAccess_method_file_exists:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **file_exists**\ (\ path\: :ref:`String<class_String>`\ ) |static| :ref:`🔗<class_FileAccess_method_file_exists>`

Returns ``true`` if the file exists in the given path.

\ **Note:** 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.

.. _class_FileAccess_method_flush:

.. rst-class:: classref-method

|void| **flush**\ (\ ) :ref:`🔗<class_FileAccess_method_flush>`

Writes the file's buffer to disk. Flushing is automatically performed when the file is closed. This means you don't need to call :ref:`flush()<class_FileAccess_method_flush>` manually before closing a file. Still, calling :ref:`flush()<class_FileAccess_method_flush>` can be used to ensure the data is safe even if the project crashes instead of being closed gracefully.

\ **Note:** Only call :ref:`flush()<class_FileAccess_method_flush>` when you actually need it. Otherwise, it will decrease performance due to constant disk writes.

:ref:`PackedStringArray<class_PackedStringArray>` **get_csv_line**\ (\ delim\: :ref:`String<class_String>` = ","\ ) |const| :ref:`🔗<class_FileAccess_method_get_csv_line>`

Returns the next value of the file in CSV (Comma-Separated Values) format. You can pass a different delimiter ``delim`` to use other than the default ``","`` (comma). This delimiter must be one-character long, and cannot be a double quotation mark.

Text is interpreted as being UTF-8 encoded. Text values must be enclosed in double quotes if they include the delimiter character. Double quotes within a text value can be escaped by doubling their occurrence. This advances the file cursor to after the newline character at the end of the line.

For example, the following CSV lines are valid and will be properly parsed as two strings each:

.. code:: text

    Alice,"Hello, Bob!"
    Bob,Alice! What a surprise!
    Alice,"I thought you'd reply with ""Hello, world""."

Note how the second line can omit the enclosing quotes as it does not include the delimiter. However it *could* very well use quotes, it was only written without for demonstration purposes. The third line must use ``""`` for each quotation mark that needs to be interpreted as such instead of the end of a text value.

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_csv_line**\ (\ values\: :ref:`PackedStringArray<class_PackedStringArray>`, delim\: :ref:`String<class_String>` = ","\ ) :ref:`🔗<class_FileAccess_method_store_csv_line>`

Store the given :ref:`PackedStringArray<class_PackedStringArray>` in the file as a line formatted in the CSV (Comma-Separated Values) format. You can pass a different delimiter ``delim`` to use other than the default ``","`` (comma). This delimiter must be one-character long.

Text will be encoded as UTF-8. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_double**\ (\ value\: :ref:`float<class_float>`\ ) :ref:`🔗<class_FileAccess_method_store_double>`

Stores a floating-point number as 64 bits in the file. This advances the file cursor by 8 bytes. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. rst-class:: classref-item-separator

.. _class_FileAccess_method_store_float:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_float**\ (\ value\: :ref:`float<class_float>`\ ) :ref:`🔗<class_FileAccess_method_store_float>`

Stores a floating-point number as 32 bits in the file. This advances the file cursor by 4 bytes. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. rst-class:: classref-item-separator

.. _class_FileAccess_method_store_half:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_half**\ (\ value\: :ref:`float<class_float>`\ ) :ref:`🔗<class_FileAccess_method_store_half>`

Stores a half-precision floating-point number as 16 bits in the file. This advances the file cursor by 2 bytes. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. rst-class:: classref-item-separator

.. _class_FileAccess_method_store_line:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_line**\ (\ line\: :ref:`String<class_String>`\ ) :ref:`🔗<class_FileAccess_method_store_line>`

Stores ``line`` in the file followed by a newline character (``\n``), encoding the text as UTF-8. This advances the file cursor by the length of the line, after the newline character. The amount of bytes written depends on the UTF-8 encoded bytes, which may be different from :ref:`String.length()<class_String_method_length>` which counts the number of UTF-32 codepoints. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. _class_FileAccess_method_store_pascal_string:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_pascal_string**\ (\ string\: :ref:`String<class_String>`\ ) :ref:`🔗<class_FileAccess_method_store_pascal_string>`

Stores the given :ref:`String<class_String>` as a line in the file in Pascal format (i.e. also store the length of the string). Text will be encoded as UTF-8. This advances the file cursor by the number of bytes written depending on the UTF-8 encoded bytes, which may be different from :ref:`String.length()<class_String_method_length>` which counts the number of UTF-32 codepoints. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. _class_FileAccess_method_store_real:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_real**\ (\ value\: :ref:`float<class_float>`\ ) :ref:`🔗<class_FileAccess_method_store_real>`

Stores a floating-point number in the file. This advances the file cursor by either 4 or 8 bytes, depending on the precision used by the current Godot build.

If using a Godot build compiled with the ``precision=single`` option (the default), this method will save a 32-bit float. Otherwise, if compiled with the ``precision=double`` option, this will save a 64-bit float. Returns ``true`` if the operation is successful.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. _class_FileAccess_method_store_string:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_string**\ (\ string\: :ref:`String<class_String>`\ ) :ref:`🔗<class_FileAccess_method_store_string>`

Stores ``string`` in the file without a newline character (``\n``), encoding the text as UTF-8. This advances the file cursor by the length of the string in UTF-8 encoded bytes, which may be different from :ref:`String.length()<class_String_method_length>` which counts the number of UTF-32 codepoints. Returns ``true`` if the operation is successful.

\ **Note:** This method is intended to be used to write text files. The string is stored as a UTF-8 encoded buffer without string length or terminating zero, which means that it can't be loaded back easily. If you want to store a retrievable string in a binary file, consider using :ref:`store_pascal_string()<class_FileAccess_method_store_pascal_string>` instead. For retrieving strings from a text file, you can use ``get_buffer(length).get_string_from_utf8()`` (if you know the length) or :ref:`get_as_text()<class_FileAccess_method_get_as_text>`.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.

.. _class_FileAccess_method_store_var:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **store_var**\ (\ value\: :ref:`Variant<class_Variant>`, full_objects\: :ref:`bool<class_bool>` = false\ ) :ref:`🔗<class_FileAccess_method_store_var>`

Stores any Variant value in the file. If ``full_objects`` is ``true``, encoding objects is allowed (and can potentially include code). This advances the file cursor by the number of bytes written. Returns ``true`` if the operation is successful.

Internally, this uses the same encoding mechanism as the :ref:`@GlobalScope.var_to_bytes()<class_@GlobalScope_method_var_to_bytes>` method, as described in the :doc:`Binary serialization API <../tutorials/io/binary_serialization_api>` documentation.

\ **Note:** Not all properties are included. Only properties that are configured with the :ref:`@GlobalScope.PROPERTY_USAGE_STORAGE<class_@GlobalScope_constant_PROPERTY_USAGE_STORAGE>` flag set will be serialized. You can add a new usage flag to a property by overriding the :ref:`Object._get_property_list()<class_Object_private_method__get_property_list>` method in your class. You can also check how property usage is configured by calling :ref:`Object._get_property_list()<class_Object_private_method__get_property_list>`. See :ref:`PropertyUsageFlags<enum_@GlobalScope_PropertyUsageFlags>` for the possible usage flags.

\ **Note:** If an error occurs, the resulting value of the file position indicator is indeterminate.
