Does anyone know if Windows XP has any command line utilities to handle
compressed (zip) files? I have a large database file that I need to copy to
the C: drive from a CD. I'm trying to keep the process as simple as
possible for the end user, so I'd like to copy a zipped version of the file,
then extract it with a batch file.

Here's the scenario:
backup.zip (@50MB) on CD
Batch file copies backup.zip to C:\temp, extracts backup.db from backup.zip

Can it be done? I'm trying to keep it simple and avoid any third-party apps
(free or not) or make any assumptions that the end-user has WinZip or
something similar installed.

Thanks.

Yes, it can be done, using the COMPACT command. Type in "Compact /?" from
the command prompt for more info.

You can only write a script. You must use Shell functions not file functions.

Set objShell = CreateObject("Shell.Application")
Set DestFldr=objShell.NameSpace(&H0)
Set SrcFldr=objShell.NameSpace("C:\Documents and Settings\David Candy\Desktop\DefaultMail.zip")
Set FldrItems=SrcFldr.Items
DestFldr.CopyHere FldrItems

I copying the entire contents of the zip maintaining directory structure

The destination folder can be hard coded like source or one of the following. EG C's 0x0000 is vbscript's &H0 - this is BASE 16 - 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, 10 (=16), 11, ..., 19, 1a, 1b, 1c, 1d, 1e, 20 (=32).
