Hi Dave, yes the process of encrypting the files makes them much less compressible. Same thing happens if you encrypt your project when you compile it.
If you are interested XiTech also make Compaxion which compress' files into a Compaxion volume file and then allows your app to seamlessly access the files simply by including their FLL library. Its very cool and has a certain level of encryption in the compression process. The only downside is that it is multiuser read but single user write. Wierd I know, but perhaps this has been changed in a newer version.
