I Have searched here, stackoverflow and 7zip docs without finding a clear answer. I am wondering:

Can I use 7zip via command line (actually using .bat file) and force archive to download via prompt?

My .bat file looks like this:

7z.exe a mathtest.zip finalmathtest\*

If this is not possible, how about sending to a users desktop? This could be an alternative for my needs.

Thanks for all input.

  • Perhaps the reason you don't get any decent answers is because your question does not make sense. "7z a mathtest.zip finalmathtest" will include the "finalmathtest" directory and all of its files and subdirectories. What does "downloading" have anything to do with this? Downloading involves copying files over a network. We can't really give you the instructions that will let you do whatever it is that you are trying to do, because we don't understand what you are trying to do. – TOOGAM Sep 15 '16 at 2:48
  • Sorry. Trying to make a bat file that is run inside a software which zips the folder "finalmathtest". The folder contains mock math tests that teachers create and will be printed out later. Currently software is opening folder but teachers requested zip file for easy emailing. Guess I am showing my age and not being clear. – Woody Sep 15 '16 at 3:03

  • Thanks. Got all the commands and have read dotnetperls.com/7-zip-examples but not getting anywhere. Was hoping for example. – Woody Sep 15 '16 at 2:15
  • use full path ok? – Tony Stewart Sunnyskyguy EE75 Sep 15 '16 at 2:25
  • Take it there is no way to force download and ask user where to save zip. So guess best solution is send zip to users desktop. Just can't figure that one out. Looking at superuser.com/questions/914084/… and still confused. – Woody Sep 15 '16 at 2:33
  • prompt path in cmd file and pipe to -o{Directory} : set Output directory – Tony Stewart Sunnyskyguy EE75 Sep 15 '16 at 3:01
  • Thanks Tony, I will try and figure out how to use the -o{Directory} within my .bat file. Your input much appreciated. – Woody Sep 15 '16 at 3:16
