I'll boot in DOS and try it if I can find a couple floppies. But I think there's something else going on. Try PKZ204.

jboy, The original post is a valid DOS question. I think you are confusing the Win32 version of PKZip with the DOS version of PKZip. PKZip 2.50 for DOS was the last version made to run in pure DOS. It also has LFN support when run in a Windows 9x environment (unlike the more common version 2.04g from 1993.) I use version 2.50 frequently myself, though it seems to be harder to find these days. To anyone (including jboy), For those who do not have it, the filesize of the self-extracting PKZIP250.exe is 207,394 bytes and the files contained within have timestamps of March 1, 1999, 2:50 AM. It is best suited for Windows 9x, as some functionality is lost in NT-based Windows. To jonpas, In viewing the manual.txt that comes with PKZip, they show the following example: pkzip a:zipfile -& Zip the current directory to drive A:, and span disks if necessary. The files currently on drive A: will not be affected. It seems that your syntax is correct, assuming you are just trying to zip the current directory. How big is this directory? You may also want to try the suggestion above regarding the use of version 2.04g, assuming you are willing to sacrifice LFN support.

Haven't used PKZIP in a while, but PKZIP does need temporary space to work. Could the source drive be full?

This might help. Using PKZIP version 204.g and DOS version 6.22. At a DOS C:\> prompt, change directory to the place you have the PKZIP.exe file. Then type the following command: pkzip -&u A:\doscopy C:\dos\*.* The -&u will “span” a .zip file across multiple diskettes if the final .zip file size would be greater than a single diskette and also formats the disks with “unconditional format” type. You will now have all files in the DOS directory zipped into a single file on three floppies. They are numbered PKBACK# 01, etc. The “doscopy” is just a name I used for the zip file that will be created. Use any name you want. CoffeeBreak

Suggest reading the addendum (rather than the manual) that downloads with PKZIP. I use release 2.04. The spanning option -&x (where x is variable) is fully explained there. It also advises self extracting files cannot span discs. Zipware is a wonderful utility, but because it has been around for many years, it has been enhanced many times and is somewhat 'facilities rich'. Usage of these is not always easily understood from the documentation. The same can be said for various failure reasons. Good luck - Keep us posted.
