Jeff,
Thanks for the input.

The wrapper is being extracted on the Mac OS X side, which still supports
the classic style file type info, as opposed to other systems such as
Windows.

Compressed files in the Binary II wrapper (.BXY) retain the file info, while
uncompressed files in the Binary II wrapper (.BNY) lose it.

That's because the uncompressed files in the .BNY wrapper depend on the
wrapper to hold their file info.

ShrinkIt compressed files (in the .BXY wrapper) use the wrapper to hold
only the ShrinkIt archive file info, which ShrinkIt doesn't really need.
The ShrinkIt archive itself contains the file info for all the archived
files.

FWIW, I've been playing with Nulib2 in conjunction with Binary II
(uncompressed) zmodem transfers. While the files transfer fine, and Nulib2
reports the correct Apple II file type info for the transferred files, when
I take the wrapper off I get a reported error and the Apple II file types
disappear, although the file data is perfectly intact and the Binary II
wrapper is removed. I'll keep working on it. I suspect in it only happening
on BNY and not BXY files.
Where are you removing the Binary II wrapper?  If you are doing it on
the PC side, there is no place to store some of the Apple II specific
information such as file type and aux type so it will just disappear.
I've heard of some programs putting this type of information in the
filename but I'm not sure if Nulib2 is one of them.

The only difference between a BNY and a BXY file is that BXY is used to
let you know that the file that is wrapped is a NuFX archive (SHK or
SDK) which should have a file type of $E0 and and aux type of $8002.
