Freeze Routing Folder & Contents

[Cayce]

I'm working on a fairly complex arrangement that has several routing folders with many member tracks, and occasionally another nested folder. I'm getting CPU overloads and would like to freeze some of these routing folders that aren't being worked on at the moment. What's the most efficient way to go about that? I know the routing folder is pretty much just an aux track, but is there a way to freeze that folder and all its members at once?

Another question would be, if I set the folder and all its contents to "inactive", does that exempt it from CPU drainage?

Thanks.
