# fileSystemRepresentation A C string containing the URL’s file system path. (read-only) ``` var fileSystemRepresentation: UnsafePointer { get } ``` ## Discussion This returns a null-terminated C string in file system representation. This string is automatically freed in the same way that a returned object would be released. The caller must either copy the string or use [`getFileSystemRepresentation(_:maxLength:)`](/documentation/Foundation/NSURL/getFileSystemRepresentation(_:maxLength:)) if it needs to store the representation outside of the autorelease context in which the value was obtained. The file system representation format is described in File Encodings and Fonts. --- Copyright © 2026 Apple Inc.
