7zip - Unzip files (7-zip) via cmd command

Question

I try to unzip a file via CMD.

So I install WinZip (and its plugin to cmd), WinRAR, and 7-zip.

But when I try to execute a command via the CMD:

7z e myzip.zip

It gives the next error:

7z is not recognized as an internal or external command

In addition, I added the folder of 7-z to the environment variables (Properties--> advanced --> Environment Variables --> user variable --> choose path, and add C:Program Files7-Zip

What can be the reason?

I find the below solution for this.

while zipping in cmd or git bash - getting error like

 7z:command not found 

solution:

• install 7z in your machine
• set the path in Environment Variables -> User Variables
  • path -> edit -> new (add the path - C:ProgramFiles7-Zip) -> OK

Now to use 7z in git bash -

• Go to C:Program Files7-Zip and copy 7z.exe file
• Go to C:Program FilesGitusrin and paste 7z.exe file

Now, you will be able to use 7z with Git Bash

Answer 1

Doing the following in a command prompt works for me, also adding to my User environment variables worked fine as well:

set PATH=%PATH%;C:Program Files7-Zip
echo %PATH%
7z

You should see as output (or something similar - as this is on my laptop running Windows 7):

C:UsersPhillip>set PATH=%PATH%;C:Program Files7-Zip
