FileAccess
==========

Type to handle file reading and writing operations.

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

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

File type. This is used to permanently store data into the user device's file system and to read from it. This can be used to store game save data or player configuration files, for example.

Here's a sample on how to write and read from a file:


.. tabs::

 .. code-tab:: gdscript

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

 .. code-tab:: csharp

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



In the example above, the file will be saved in the user data folder as specified in the :doc:`Data paths <../tutorials/io/data_paths>` documentation.

There is no method to close a file in order to free it from use. Instead, **FileAccess** will 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.


.. tabs::

 .. code-tab:: gdscript

    var file = FileAccess.open("res://something") # File is opened and locked for use.
    file = null # File is closed.

 .. code-tab:: csharp

    using var file = FileAccess.Open("res://something"); // File is opened and locked for use.
    // The using statement calls Dispose when going out of scope.



\ **Note:** To access project resources once exported, it is recommended to use :ref:`ResourceLoader<class_ResourceLoader>` instead of the **FileAccess** API, as some files are converted to engine-specific formats and their original source files might not be present in the exported PCK package.

\ **Note:** Files are automatically closed only if the process exits "normally" (such as by clicking the window manager's close button or pressing **Alt + F4**). If you stop the project execution by pressing **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**

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

- void **set_big_endian** **(** :ref:`bool<class_bool>` value **)**
- :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:** :ref:`big_endian<class_FileAccess_property_big_endian>` is only about the file format, not the CPU type. The CPU endianness doesn't affect the default endianness for files written.

\ **Note:** This is always reset to ``false`` 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_eof_reached:

.. rst-class:: classref-method

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

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** **(** :ref:`String<class_String>` path **)** |static|

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. See :ref:`ResourceLoader.exists<class_ResourceLoader_method_exists>` for an alternative approach that takes resource remapping into account.

For a non-static, relative equivalent, use :ref:`DirAccess.file_exists<class_DirAccess_method_file_exists>`.

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

----

.. _class_FileAccess_method_flush:

.. rst-class:: classref-method

void **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.

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

----

.. _class_FileAccess_method_get_16:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_16** **(** **)** |const|

Returns the next 16 bits from the file as an integer. See :ref:`store_16<class_FileAccess_method_store_16>` for details on what values can be stored and retrieved this way.

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

----

.. _class_FileAccess_method_get_32:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_32** **(** **)** |const|

Returns the next 32 bits from the file as an integer. See :ref:`store_32<class_FileAccess_method_store_32>` for details on what values can be stored and retrieved this way.

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

----

.. _class_FileAccess_method_get_64:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_64** **(** **)** |const|

Returns the next 64 bits from the file as an integer. See :ref:`store_64<class_FileAccess_method_store_64>` for details on what values can be stored and retrieved this way.

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

----

.. _class_FileAccess_method_get_8:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_8** **(** **)** |const|

Returns the next 8 bits from the file as an integer. See :ref:`store_8<class_FileAccess_method_store_8>` for details on what values can be stored and retrieved this way.

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

----

.. _class_FileAccess_method_get_as_text:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_as_text** **(** :ref:`bool<class_bool>` skip_cr=false **)** |const|

Returns the whole file as a :ref:`String<class_String>`. Text is interpreted as being UTF-8 encoded.

If ``skip_cr`` is ``true``, carriage return characters (``\r``, CR) will be ignored when parsing the UTF-8, so that only line feed characters (``\n``, LF) represent a new line (Unix convention).

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

----

.. _class_FileAccess_method_get_buffer:

.. rst-class:: classref-method

:ref:`PackedByteArray<class_PackedByteArray>` **get_buffer** **(** :ref:`int<class_int>` length **)** |const|

Returns next ``length`` bytes of the file as a :ref:`PackedByteArray<class_PackedByteArray>`.

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

----

.. _class_FileAccess_method_get_csv_line:

.. rst-class:: classref-method

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

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.

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

::

    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.

.. _class_FileAccess_method_get_double:

.. rst-class:: classref-method

:ref:`float<class_float>` **get_double** **(** **)** |const|

Returns the next 64 bits from the file as a floating-point number.

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

----

.. _class_FileAccess_method_get_error:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **get_error** **(** **)** |const|

Returns the last error that happened when trying to perform operations. Compare with the ``ERR_FILE_*`` constants from :ref:`Error<enum_@GlobalScope_Error>`.

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

----

.. _class_FileAccess_method_get_file_as_bytes:

.. rst-class:: classref-method

:ref:`PackedByteArray<class_PackedByteArray>` **get_file_as_bytes** **(** :ref:`String<class_String>` path **)** |static|

Returns the whole ``path`` file contents as a :ref:`PackedByteArray<class_PackedByteArray>` without any decoding.

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

----

.. _class_FileAccess_method_get_file_as_string:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_file_as_string** **(** :ref:`String<class_String>` path **)** |static|

Returns the whole ``path`` file contents as a :ref:`String<class_String>`. Text is interpreted as being UTF-8 encoded.

----

.. _class_FileAccess_method_store_16:

.. rst-class:: classref-method

void **store_16** **(** :ref:`int<class_int>` value **)**

Stores an integer as 16 bits in the file.

\ **Note:** The ``value`` should lie in the interval ``[0, 2^16 - 1]``. Any other value will overflow and wrap around.

To store a signed integer, use :ref:`store_64<class_FileAccess_method_store_64>` or store a signed integer from the interval ``[-2^15, 2^15 - 1]`` (i.e. keeping one bit for the signedness) and compute its sign manually when reading. For example:


.. tabs::

 .. code-tab:: gdscript

    const MAX_15B = 1 << 15
    const MAX_16B = 1 << 16
    
    func unsigned16_to_signed(unsigned):
        return (unsigned + MAX_15B) % MAX_16B - MAX_15B
    
    func _ready():
        var f = FileAccess.open("user://file.dat", FileAccess.WRITE_READ)
        f.store_16(-42) # This wraps around and stores 65494 (2^16 - 42).

        var converted1 = unsigned16_to_signed(read1) # -42
        var converted2 = unsigned16_to_signed(read2) # 121

 .. code-tab:: csharp

    {
        using var f = FileAccess.Open("user://file.dat", FileAccess.ModeFlags.WriteRead);
        f.Store16(unchecked((ushort)-42)); // This wraps around and stores 65494 (2^16 - 42).
        f.Store16(121); // In bounds, will store 121.
        f.Seek(0); // Go back to start to read the stored value.
        ushort read1 = f.Get16(); // 65494
        ushort read2 = f.Get16(); // 121
        short converted1 = (short)read1; // -42

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

----

.. _class_FileAccess_method_store_8:

.. rst-class:: classref-method

void **store_8** **(** :ref:`int<class_int>` value **)**

Stores an integer as 8 bits in the file.

\ **Note:** The ``value`` should lie in the interval ``[0, 255]``. Any other value will overflow and wrap around.

To store a signed integer, use :ref:`store_64<class_FileAccess_method_store_64>`, or convert it manually (see :ref:`store_16<class_FileAccess_method_store_16>` for an example).

----

.. _class_FileAccess_method_store_csv_line:

.. rst-class:: classref-method

void **store_csv_line** **(** :ref:`PackedStringArray<class_PackedStringArray>` values, :ref:`String<class_String>` delim="," **)**

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.

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

----

.. _class_FileAccess_method_store_double:

.. rst-class:: classref-method

void **store_double** **(** :ref:`float<class_float>` value **)**

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

----

.. _class_FileAccess_method_store_line:

.. rst-class:: classref-method

void **store_line** **(** :ref:`String<class_String>` line **)**

Appends ``line`` to the file followed by a line return character (``\n``), encoding the text as UTF-8.

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

.. _class_FileAccess_method_store_pascal_string:

.. rst-class:: classref-method

void **store_pascal_string** **(** :ref:`String<class_String>` 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.

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

----

.. _class_FileAccess_method_store_real:

.. rst-class:: classref-method

void **store_real** **(** :ref:`float<class_float>` value **)**

Stores a floating-point number in the file.

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

----

.. _class_FileAccess_method_store_string:

.. rst-class:: classref-method

void **store_string** **(** :ref:`String<class_String>` string **)**

Appends ``string`` to the file without a line return, encoding the text as UTF-8.

\ **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>`.

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

----

.. _class_FileAccess_method_store_var:

.. rst-class:: classref-method

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

Stores any Variant value in the file. If ``full_objects`` is ``true``, encoding objects is allowed (and can potentially include code).

Internally, this uses the same encoding mechanism as the :ref:`@GlobalScope.var_to_bytes<class_@GlobalScope_method_var_to_bytes>` method.

\ **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_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_method__get_property_list>`. See :ref:`PropertyUsageFlags<enum_@GlobalScope_PropertyUsageFlags>` for the possible usage flags.
