As I don't own PPP I also would like to know what a PZP is. I've got a list of PPP files and I can see no trace of any PZP. As Routledge said I tought compressed .PZ3 were .PZZ. Please ronknights can you confirm your assertion on PZP ? Are there 2 kind of compressed .PZ3 or what ? btw I need to know this for P3dO management of course.
