Thanks George. In fact, I deleted enough useless files on one of these HD's to re-open that in box. In fact, I found some interesting things: Rick mentions in one message that Working Directory reference numbers are incorrectly, and commonly referred to as volume reference numbers. He also mentions things about _real_ volume reference numbers, like that -1 is usually the startup volume, which makes alot of sense now. I also found your message just minutes ago about the GetWDRefNum function, and my only question would have been about the _"PGGP", but then you reposted with: >_myProcID = _"PGGP" {You need your app's signature here} ...and it made a little more sense. :-) Anyway, after implementing that routine, everything seems to be working 100% ...Thanks again! ~ Nobody ever says, "I wanna be an STR resource when I grow up." ~ -- TJ Grant (tatewake@...)
