However, to open ram or rm files in kfm, select "Edit" -> "Mime Types" (or
"Global Mime Types" as root)in kfm. You're presented with your Mime Types for
KDE. Select the "audio" folder. Now create a new Mime Type by rightclicking and
selecting "New" -> "Mime Type". You are questioned for the name of the new
type. Type "vnd.rn-realaudio.kdelnk" for the Mime Type
"audio/vnd.rn-realaudio". After pressing enter, you are are asked about some
things about your new Mime Type like Icon, Description, ...
Don't forget to reenter the full Mime Type in the corresponding field. And
certainly, you should select the RealPlayer as default application for this
type. If you can't find it in the List, see below.
See your RealPlayer Documentation for a complete list of Mime Types for the
Player. For each of them, you must complete the upper procedure.

If you can't find RealPlayer in the "Default App" list of the Mime Types, then
you must select "Edit" -> "Applications" (or "Global Applications" as root) in
kfm (Before that, you should first create ALL RealPlayer Mime Types). There you
can add new "default Apps". Select a good group - I would suggest "Multimedia"
or so - and there, create a new App (righclick -> "New" -> "Application"). As
Name, you can use "RealPlayer" or "RealPlayer G2"...
Then you can enter the Properties for the Application "RealPlayer". Here it is
most important, to select the right executeable. If the player is started with
"rvplayer" (and this is in your default path), you simple enter "rvplayer"
else, you must enter the full path.
And don't forget to select all RealPlayer Mime Types. Only by selecting a Mime
Type, it is possible to select this App as default in the Mime Type Properties.
