Does Windows 7 have unzip at the command line installed by default?

Question

There is a zip/unzip option in the context menu so is it accessible from the command line?

Answer 1

Yes and no.

The yes:

rundll32.exe zipfldr.dll,RouteTheCall filename.zip

would open the file in the explorer as a "compressed folder" similar to clicking open a zip folder

The no:

There is no other entry point in zipfldr.dll that allows decompressing files directly from command line. I would suggest using the 7zip command utilities or unzip.exe as these are free (as in freedom as well as in beer)

Answer 2

If you already have Java JDK on your PC, and the bin directory is in your path (in most cases), you can use the command line:

C:\Program Files\Java\jdk1.7.0_45\bin>jar xf test.zip

Complete set of options for the jar tool available here.

Examples:

Extract jar file

jar x[v]f jarfile [inputfiles] [-Joption]
jar x[v] [inputfiles] [-Joption]

If you don't have JDK installed I would recommend installing 7-Zip, since it's very lightweight: http://www.7-zip.org/
