For most folders in Windows 7 Explorer context menu has the items "Play in foobar2000" and "Enqueue", but for some, they are replaced with similar items of Windows Media Player. Some logic in this volatility, I do not watch. And "play all" (if you go to folder) brings to life exactly fubar 1.1; all the music files successfully associated with them.
How to do so in the context menu of the folder these two items have always been?
