# Core Foundation URL Access Utilities

## Overview

Core Foundation URL Access Utilities give you convenient system-independent methods of creating, reading, updating, or deleting a URL resource.

Given a [`CFURL`](/documentation/CoreFoundation/CFURL) object that holds either a file or http URL, you can read the resource’s data with the [`CFURLCreateDataAndPropertiesFromResource(_:_:_:_:_:_:)`](/documentation/CoreFoundation/CFURLCreateDataAndPropertiesFromResource(_:_:_:_:_:_:)) function. You can write data to the URL resource, possibly creating a new file, with the [`CFURLWriteDataAndPropertiesToResource(_:_:_:_:)`](/documentation/CoreFoundation/CFURLWriteDataAndPropertiesToResource(_:_:_:_:)) function. Finally, you can destroy, or delete, the resource pointed to by the URL with the [`CFURLDestroyResource(_:_:)`](/documentation/CoreFoundation/CFURLDestroyResource(_:_:)) function.
