  In the example above, the file will be saved in the user data folder as specified in the [url=$DOCS_URL/tutorials/io/data_paths.html]Data paths[/url] documentation.
- [FileAccess] will close when it's freed, which happens when it goes out of scope or when it gets assigned with [code]null[/code]. In C# the reference must be disposed manually, which can be done with the [code]using[/code] statement or by calling the [code]Dispose[/code] method directly.

+ [FileAccess] will close when it's freed, which happens when it goes out of scope or when it gets assigned with [code]null[/code]. [method close] can be used to close it before then explicitly. In C# the reference must be disposed manually, which can be done with the [code]using[/code] statement or by calling the [code]Dispose[/code] method directly.
  [b]Note:[/b] To access project resources once exported, it is recommended to use [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.
  [b]Note:[/b] Files are automatically closed only if the process exits "normally" (such as by clicking the window manager's close button or pressing [b]Alt + F4[/b]). If you stop the project execution by pressing [b]F8[/b] 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 [method flush] at regular intervals.
