I have a source zip file which is located in a user's "My Documents" directory. It is guaranteed to always be there. I'm looking for a way to create a batch or script which will let me unzip that file to a destination directory also within the user's directory. If the destination is already there, it should first delete the existing destination folder.

Example process:

srcFile = %user%\My Documents\file.zip
destFolder = %user%\My Documents\Unzipped\
if destFolder exists, delete it
unzip srcFile to destFolder

I'm looking for a solution that will work on Windows XP and Windows 7. If possible, I don't want to use a zip application other than the one built into Windows XP/7.

We're not here as a script writing service. ;) So, what have you got so far, and where are you getting stuck? –  Ƭᴇcʜιᴇ007 May 28 '13 at 18:50
Your last sentence is problematic. Not only does the Compressed Folders function suck, it's not possible to access from the command line AFAIK. You'll probably have to invoke a VBS script from your batch file. If you use a 3rd party command line unzipper what you want to do is really trivial. –  Karan May 28 '13 at 19:10

RD /S /Q "%USERPROFILE%\My Documents\Unzipped"
cscript UnzipZip.vbs


strZipFile  = "\file.zip"
strUnzipped = "\Unzipped\"

Sub UnZip(ExtractTo,ZipFile)

Set fso = CreateObject("Scripting.FileSystemObject") 
    If NOT fso.FolderExists(ExtractTo) Then 
End If 

Set objShell = CreateObject("Shell.Application") 
Set FilesInZip=objShell.NameSpace(ZipFile).items 

Set fso = Nothing 
Set objShell = Nothing 
End Sub

set WshShell = WScript.CreateObject("WScript.Shell")
strDesktop = WshShell.SpecialFolders("MyDocuments")

strZipPath   = strDesktop & strZipFile
strUnzipPath = strDesktop & strUnzipped

UnZip strUnzipPath , strZipPath

I get an error on the last line: "Cannot use parentheses when calling a Sub". Any thoughts on what to fix? –  Michael Mankus May 29 '13 at 11:15
@MichaelMankus Sorry, fixed. –  STTR May 29 '13 at 17:11

Here I've tried to summarize ways of how can files and folder be zipped without external tools:

And also tried to create a tool for common usage capable of zipping unzipping and few more features. ZIPJS.BAT - it does not need additional files like .vbs nor creates a temp ones.All in one and called like a normal bat file.

to unzip folder of file you can use this:

// unzip content of a zip to given folder.content of the zip will be preserved (-keep yes).Destination will be overwritten (-force yes)
call zipjs.bat unzip -source C:\myDir\myZip.zip -destination C:\MyDir -keep yes -force yes
