I wonder if there is a possibility in foobar to start other programs via the context menu and pass them parameters like filepath or tag values.

Say... that's not a half bad idea. Though off the top of my head, I can't think of any programs to launch. What were you thinking?

Well, mainly because I use another program to tag files, so this would make things a littler easier.
Can't give any other exemples at the moment.
And I saw this feature in some other programs, too.

yeah how's about a context menu for opening media player classic

This is a really good idea. I would find this very helpful.

Any way to do it?

Use foo_openwith plugin.

Or foo_run

Is there a plugin/way of getting either of these plugins to automatically launch an external program for certain types of files, and also to show files not supported by foobar in the playlist? I'd use this to automatically open real/quick/wmv etc. files in my media folders with Media Player Classic.
