Something else that you might want to consider is this: go to www.wolfiesgate.com and get a copy of the bryce Librarian. It will export materials, obp, and Bryce 3 skies. It will even let you swap entire preset files out (I think while bryce is running. Don't have either here to check). It's been updated for Bryce 4 (sorta). He does say on his site that it'll work for B4, just won't handle the .BSK files ... :) HTH, John PS - from what I understand (reading the manual and talking to other users) the capability of custom folders was on the drawing board when the manual was sent to the printers but was scrapped when time constraints and managerial interference started to hit in a major way. Hopefully, Corel will pick this up and run with it for B5.
