Making a DOS .ZIP Archive
$ ZIP/LEVEL=9/PKZIP archive_name filespec
$ ZIP -9k archive_name filespec
Use this for Binary files ONLY!
ASCII files (. COM, .TXT, etc.) might not Unzip correctly!
Notes:
To make a .ZIP archive for use on DOS or Windows, use the /PKZIP qualifier.
For binary files, leave out the /TRANSLATE_EOL qualifier. This will prevent extraneous data from being inserted into the files being archived.
Note that ASCII (text) files may not be stored in the archive in a usable condition if the /TRANSLATE_EOL is not used.
