## Detailed Description

FileInfo implements methods for getting information that all files should contain, and allows for manipulation of extended attributes.

See FileAttribute for more information on how GIO handles file attributes.

To obtain a FileInfo for a File, use File::query_info() (or its async variant). To obtain a FileInfo for a file input or output stream, use FileInput::stream_query_info() or FileOutput::stream_query_info() (or their async variants).

FileAttributeMatcher allows for searching through a FileInfo for attributes.
