You can use the cabviewer from XP+

The key is centered around: CreateObject("MakeCab.MakeCab.1")

Here is the basis of the cab stuff..

The only built-in features of XP that control Zip files are not available to batch files.  I would suggest getting 7-zip.  The 7z.exe is available at command line.

7-Zip: http://www.7-zip.org
REM Unzips all files in the current direcotry to the current directory
for %%f in (*.zip) do "C:\Program Files\7-Zip\7z.exe" x "%%f"

Open in new window

This script is written in VBScript. Save it co unzip.vbs and run it by cscript /nologo unzip.vbs PathToZippFolder
On Error Resume Next
  Dim fso, folder, files, NewsFile,sFolder
  Set fso = CreateObject("Scripting.FileSystemObject")
  sFolder = Wscript.Arguments.Item(0)
  If sFolder = "" Then
      Wscript.Echo "No Folder parameter was passed"
  End If
  Set folder = fso.GetFolder(sFolder)
  Set files = folder.Files
  For each file In files
   If Right(File.Name,4) = ".zip" Then
    Wscript.Echo File.Name
    Unzip File.Name,sFolder
  End IF

Sub UnZIP (ZipFile,ExtractTo)

'If the extraction location does not exist create it.
Set fso = CreateObject("Scripting.FileSystemObject")
If NOT fso.FolderExists(ExtractTo) Then
End If
Wscript.Echo ExtractTo & "\" & ZipFile

set sa = CreateObject("Shell.Application")
set FilesInZip = sa.NameSpace(ExtractTo & "\" & ZipFile).items
Set fso = Nothing
Set sa = Nothing
End Sub

In my script you do not need to install any external ZIP programs. I am using buil-in ZIP functionality.
Some lines you can remove because I use it for debugging the script. The script is doing:
find all zip files in specified directory and to the same directory unzip them. That is all.


thanks for your help!  i'll try the vb script and if that becomes over my head, i'll look into the other suggestions provided here.  I'll report back with my outcome.

...and if the .zip file has a password?!
