+        <summary>This method tries to locate an icon in icon_theme that can be used to represent the file passed. It can optionally also look for existing thumbnails. It does no I/O, so the lookup should be relatively fast.
+If you don't know any information about the file already you can use <see cref="M:Gnome.Icon.LookupSync" /> method which gets this information using <see cref="N:Gnome.Vfs" />.</summary>
+        <returns>The value returned is a <see cref="T:System.String" /> which is the name in absolute path of an image to use for the file.</returns>
