zip error after 7-zip install and uninstall

I am using zip in Cygwin under Windows 10 and after installing 7-Zip on my system and then uninstalling it, I get the following error when using zip on the command line in Cygwin when trying to zip any files:

    zip warning: name not matched: Files\7-zip
    zip warning: name not matched: testing

E.g. zipping 2 files a and b:

zip testing a b

will give the error. How do I get rid of this nuisance? Reinstalling zip did not help.

Solution

  • After a further extensive search with no answers I found out what the problem was.

    7-Zip sets up an environment variable ZIP=C:\Program Files\7-zip and for some reason the existence of a ZIP variable interferes with the GNU zip utility.

    I unset ZIP by doing ctrl-Esc and typing env which brought up the control panel option of "Edit environment variables for your account" and removed the ZIP variable and it now works.
