CW-MM Classes are a complete replacement for the multimedia classes coming with MMOS2.


  • Complete replacement for the multimedia classes included with OS/2
  • Integrates MP3 and OGG files with the WPS
  • Audio details of any audio class in folder details view
  • Audio details of any audio class in the settings notebook
  • ID3 tags in the details view of folders
  • ID3 tag editing in the settings notebook
  • Media folder plays any audio file class
  • Playlists (the folder content is the playlist)
  • ID3 tag display in player
  • New shadow class showing audio details in folder details view.
  • CD player with FreeDB support
  • Control playing using setup strings
  • Audio device sharing
  • M3U playlist editor
  • Audio stream object for listening to Icecast servers (no, it doesn't work with SHOUTcast or others)
  • Image file information in the settings and the details view
  • New JPEG IO-procedure included which may read progressive JPEG files
  • Improved light table folder with settable preview size.
  • Caching of information to speed up folder opening
  • REXX interface if WPS-Wizard V0.2.0 is installed
  • Of course multithreaded 32 bit OO design (thus being fully buzzword compliant).

This project was formerly referred as Multimedia Extensions on some older Netlabs page.


  • CW-MM Classes are included with (and installed by) ArcaOS



  • CW-MM Classes are open source software released under the GNU General Public License version 2.


  • Chris Wohlgemuth
  • Klaus Staedtler-Przyborski (fearless beta testing)
  • Steven H Levine (initial SVN commit of sources)
  • OS/2 Netlabs (project hosting)
  • All those we missed (it was purely unintentional)
