Hi Does Windows 7 come with a native uncompress (unzip) tool that can be run from the command-line? I am looking for native uncompress solution so that users do not have to either provide a third-party Unzip tool or for me having to create a self-extraction file.Thanks Jeff in Seattle

I'm not aware of a command line option to unzip files. The normal way would be to right-click on the compressed file (note: only *.zip format is supported) and select "extract all", following the instructions then. If you want more flexibility, you must use 7zip or something like that (WinRAR, f.e.). The native solution is somewhat restricted, probably by licensing issues."I think there is a world market for maybe five computers. (Thomas J. Watson, Sr.)

Hi, According to my search, if you want to unzip file using command line, additional software maybe needed. Here are more information: http://stahlworks.com/dev/index.php?tool=zipunzip http://www.memecode.com/docs/winzip.html Hope it helps.Vivian Xing - MSFT

The stahlwordk unzip seems to be built for 1999 zip files and doesn't work with a zip file I just created with windows 7, do you have a pointer to a working tool?

There's a way to unzip with explorer in vbscript, but I've just started using 7-zip: http://www.7-zip.org Keep 7z.exe and 7z.dll together.
