When you use PKZIP.EXE with the ampersand (&) switch to span multiple floppy disks, the following error message appears:
The name specified is not recognized as an internal or external command, operable program or batch file.


The ampersand switch is not interpreted by the Command Prompt (CMD.EXE) because it is a reserved command character, used to separate multiple commands on one line. Therefore, the characters following the ampersand are interpreted as a bad name.


To work around this problem, use the carrot character (^), above the "6" key, which allows you to input command characters as text. For example, to compress the C:\DATA directory over multiple floppy disks on the A drive, you would use the following command:

Alternatively, you can surround the ampersand character with quotes such as follows:

PKZIP is manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
