Most Zip utilities have a command line option to do this.  Whick one are you using?

If you are using Winzip then you just right click on the file and the click on delete

I realize that, you can still call may of the Zip utilities from VB.  Hence the question as to what you were currently using.

Hi

   I am using zip32.dll and unzip32.dll. Do you
have some code that i can use to remove the file when
the file name is known.

   Otherwise i have unzip the whole zip file and only
zip the files that i need. Since the file i have to unzip
has a lot of sub folders its quite cumbersome.  

Thanx alot

I suspect that you are referring to the Info-Zip libraries that Eric (emoreau) recommended earlier on, with the link http://vbaccelerator.com/codelib/zip/zipvb.htm

So I will let him explain how to use them, as I am unfamiliar with them.

I have never seen a delete function into the zip librairie. One way of doing it is to unzip in a folder, delete the file and rezip the folder.

Maybe, you could also use the command line of WinZip (I don't know the switches) to delete one of the file.
