Not easily. Apparently, it is possible with Visual Basic/Script to open
a ZIP folder and access its files. Too hard for me. If you really want
to, have a look at Eduardo A. Morcillo's CompressedFolder.cls at
<
http://www.mvps.org/emorcillo/vb6/shell/xpzip.shtml>.
I haven't found any command line functions to manipulate ZIP files with
built-in tools, except:
rundll32.exe zipfldr.dll,RouteTheCall fubar.ZIP
which will open the ZIP folder in a GUI.
The only way I know to manipulate ZIP files from the command line is to
get WinZip and its command line adjuncts wzzip and wzunzip; then:
wzzip -a fubar.ZIP file.any
will add file.any to the ZIP archive fubar.ZIP
I suppose that DynaZip/InnerMedia, where MS got this feature, may supply
similar tools, as will probably a number of others (PKZIP springs to
mind).
