DOS 3.3 File Compression

[Doug McComber <doug.mccomber+csa2@gmail.com>]

Hi,

I have a BBS (complete with a dedicated dial-up line at 902-252-1944) 
that I am populating with Apple II software amongst others.  My goal with 
this is for the software to be in a format that someone calling the BBS 
from an actual Apple II (vice emulator on a PC) can use natively.

One method I'm using is ShrinkIt for files and disks.  But what should I 
use if I want to compress a handful of DOS 3.3 files but not the whole 
disk?

Thanks,
Doug
