Sketchup to VMF - Cant find the plugin!

The plugin to convert sketchup files to valve map files for use in hammer should be, on lnstallation, in a folder called stetchup here -C:\Program Files\Steam\steamapps\USERNAME\sourcesdk\sketchup ( )

The files needed are
-valve (folder)
-valve_library (folder)

I havn’t got the files so could anyone post a link to were i can download them or send them, if you have it, to
