Solve : How to extract zip file using inbuilt Dos command of Windows XP?

Answer»

Hi,

I would like to have dos command to extract zip files.
Note: i cannot use third party software like winzip and winrar.

For OS above XP 'compressed (zipped) FOLDER' facility is available, where you right click folder and click 'send to' -> ''compressed (zipped) folder', a zip file will be CREATED within that folder.
Now select this zip file and right click, 'extract all' menu will be available.
If you select this, wizard will open to extract file.
I want this through Dos Prompt so that i can use it in my batch file.

Thanks
I'm not aware you can do this at the prompt without a third party program. You can however create a your own command and have it run from the prompt or a batch file.

Unzip
Code: [Select] strZipFile = "" 'name of zip file
outFolder = "" 'destination folder of unzipped files

Set objShell = CreateObject( "Shell.Application" )
Set objSource = objShell.NameSpace(strZipFile).Items()
Set objTarget = objShell.NameSpace(outFolder)
intOptions = 256
objTarget.CopyHere objSource, intOptions

Fill in the appropriate names for the zip file and the output folder (must be quoted). Save the script with a vbs extension. In your batch file you can run the script with this entry: cscript //nologo scriptname.vbs

Good luck.

Note: option 256 displays a progress dialog box but does not SHOW the file names. Thanks for the info! Hopefully you can help me with an issue on this...

In a folder I have the following 3 files:

test.zip
unz.bat
unz.vbs

When I run unz.bat in a command window, the following message displays:

unz.vbs(5, 1) (null): The system cannot find the file specified.

When a friend runs my same files on his XP machine, it runs fine. Is there a system file I am missing?

This is the contents of my files:

file: unz.bat
--------------------------------

cscript //nologo unz.vbs


file: unz.vbs
--------------------------------

strZipFile = "c:\DONZ\test.zip"
outFolder = "c:\DONZ\"

Set objShell = CreateObject( "Shell.Application" )
Set objSource = objShell.NameSpace(strZipFile).Items()
Set objTarget = objShell.NameSpace(outFolder)
intOptions = 256
objTarget.CopyHere objSource, intOptions

Thank you for any help!
Does the folder containing those files have a long file name or a name with spaces?

You may have to put the entire path name after cscript //nologo.

For example, if you have those files in C:\Unzipping Path, you'll have to use this:

cscript //nologo "C:\Unzipping Path\unz.vbs"I used the same script and get the following error:

Microsoft VBScript runtime error: Object REQUIRED: 'objShell.NameSpace(...)'

Here is my code:
Code: [Select]strZipFile = "c:\documents and settings\%username%\fr5\resource.zip"
outFolder = "c:\documents and settings\%username%\fr5\"

Set objShell = CreateObject( "Shell.Application" )
Set objSource = objShell.NameSpace(strZipFile).Items()
Set objTarget = objShell.NameSpace(outFolder)
intOptions = 256
objTarget.CopyHere objSource, intOptions
I've checked, retyped the code, copied the code, etc. What am I missing?Quote
I used the same script and get the following error:

The same script would have worked!

In this context, the username variable needs to be expanded:

Code: [Select]Set WshShell = CreateObject("Wscript.Shell")
user = WshShell.ExpandEnvironmentStrings("%UserName%")

strZipFile = "c:\documents and settings\" & user & "\fr5\resource.zip"
outFolder = "c:\documents and settings\" & user & "\fr5\"

Set objShell = CreateObject( "Shell.Application" )
Set objSource = objShell.NameSpace(strZipFile).Items()
Set objTarget = objShell.NameSpace(outFolder)
intOptions = 256
objTarget.CopyHere objSource, intOptions

Everything else being equal, this should work. Thanks, Sidewinder. Worked like a charm. Hey guys. I hope someone is still looking at this thread as I require some help and quite urgently. The unzip seems to be working fine but the files I receive is always named differently because they contain a date and they are password encrepted. How can I specify the password in the script and also tell it to extract all files inside a certain directory not just one? Thanks in advanceQuote

This would be reason number one why you should start your own thread. Many people will see this thread with 7 replies and deduce that there is NOTHING more to add. Reason number two is that it is considered rude to hijack someone else's thread, no matter how old.

Use the same algorithm as the sender to determine the received file name. You might also determine what files are in the receive directory, and sequentially unzip each one.

Did you use some 3rd party program to compress your files? Windows compressed files don't have a password option and they cannot be encrypted.

Need more info. .ZIP folders have the option of having a password to prevent the extraction of the files...also prevents WinRAR from extracting as well.Hi All,
