Dear Murali,

see this thread earlier in the Statalist or search it in Google:

"st: Undocumented zip/unzip capabilities of Stata 10"

Although it is undocumented, it works fine so far and I believe it is
going to stay with us because of:

" 22.  Official ado updates may now be distributed as a compressed archive.
         This can make updates significantly faster for those with a slow
         internet connection."

http://www.stata.com/help.cgi?whatsnew
Stata executable, all platforms

But Stata developers might, of course, decide otherwise in the future.

Note that it is very easy to extract several files at once with this command:

//-------------------------------------
unzipall.ado------------------------------------------------
// Sergiy Radyakin, 2007-2008
// This is a wrapper to an undocumented unzipfile command in Stata 10
// It may or may not work in the later versions.
// It does not work in any version prior to 10.
// Use at your own risk, e.g.:

// unszipall, from("c:\temp\myarchive.zip") to("c:\unpacked")
//            overwrite password("mypassword")


program unzipall
 version 10.0
 syntax ,from(string) [to(string) overwrite password(string)]

 local  startdir `"`c(pwd)'"'
 if missing(`"`to'"') local `"`to'"' `"`startdir'"'
 quietly cd `"`to'"'
 unzipfile `"`from'"', `overwrite' password(`"`password'"')
 quietly cd `"`startdir'"'
end

// -------------------------------- end of unzipall.ado
--------------------------------------------



The benefit of using this code is of course that you don't have to
install anything in addition to the .ado file, such as the unzip
utility that Dr. Stovring mentions in the help file for -zipuse-.


Best regards,
    Sergiy Radyakin
