G'day Andrew,

How many files/subdirectories are already in your root directory?

Many DOSs are limited to 255 or 511 entries in root on the HD, or 127
entries in root on a floppy.  Note that directories are treated as
"files" for this count. Try copying your ZIPs to a _subdirectory_. There
is no limit to the number of entries in a subdirectory; although you
will eventually run out of disk space... ;-)


This reminds me of an amusing episode which occurred some years ago at
the lab I was (then) working in.  All the computers had just been
upgraded from 720kB to 1.44MB floppy drives; but "the new drives were
faulty" because they would never store more than ~900kB of files per
1.44MB disk.  The lab managers had counted on storing about 200
Lotus-123 spreadsheets per disk; to be sent to clients with our reports.

After management had spent much $$$ on new drives, drive recalibrations,
upgrading to MS-DOS 4.01, etc; I happened to read one of Peter Norton's
books which mentioned the DOS root directory limitation.  It turned out
that not only were we storing everything in "A:\" by default, but we
were saving an "Allways" file for every spreadsheet too (Allways was a
graphical publishing add-on for 123).  We were trying to put about 400
files in each floppy's root directory.

The cure?  Create the directory "A:\123\" on each floppy, and stuff all
the files in this.  I got paid an extra week's salary for this idea!
