.GZ (GNU) Files???

[ab616@ccn.cs.dal.ca (Tony Cianfaglione)]

   How come the GNU (.GZ) compressed files, when uncompressed and form 143K 
files, do not fit on a 5.25" disk? The files at CDROM uncompress to form 
143k disk files, yet once a disk is formatted, only 137k remains.
   Also, the few that fit rendered a message 'Unable To Load Prodos'. 

   Granted, these files are designed to be used with PC emulators but 
they are supposedly able to be used with Apple II's as well. Even 
Shrinkit won't restore the file to disk because it was a full disk at the 
beginning and wasn't shrunk, just GNU-compressed.

   Anybody have any ideas??

Thanks,  Tony
