 - Description: The Filesystem package of the CMS (`\Joomla\CMS\Filesystem`) has been deprecated for a long time. For Joomla 6.0 it has been moved to the compat plugin and will finally be completely removed in 7.0. Please use the [framework `Filesystem`](https://github.com/joomla-framework/filesystem) package (`\Joomla\Filesystem`). The packages can be used nearly interchangeably, with the exception of `File::exists()` and `Folder::exists()`. Please use `is_file()` and `is_dir()` directly.
