Thanks for the suggestions! I try to keep about 30% of the SSD free, and since I don't use RB, it sounds OK to delete the folder and any shortcuts. I was worried about BIAB trying to access things in the folder, but sounds like they are pretty independent. Guess I'll have to replace my 800gb SSD with one of those bigger drives one of these days.

Since I mostly use BIAB via the DAW plugin, I'm hoping the plugin doesn't barf if the RB stuff was deleted.
