In Windows XP I could set parameters for "opens with" so that a program gets opened with an application and the extra parameters are passed to it. I could also set different associations other than "opens with" such as "add to play list". that would then apear in explorer right click menu. this apeared in the windows explorer ->tools-> menus-> folder options menu.
However these options dont seem to be available, or at least not in the same place in windows 7 (64 home premium), all I can find is the same dialogue which gives me only the "opens with" association and no options for command line parameters.
please note this is probably an advanced feature, so dont be alarmed if you dont understand it, also you can assume ive already gone through all the basic menus and basic help. also note this question is not about how to add to windows play list, but how to add any such option to the windows explorer right click context menu.
