Vista - Read zip files? Remove targeted file?

New to PowerShell and need to know if there is the capability to read
through zip files targeting a specific file extension and removing the
target from each archive?

With built-in functions using essentially the Windows zip folders support I
can't seem to do better than do what you want but getting a file comfimation
dialog box for each file to delete:

$shellApp = new-object -com shell.application
$zipFile = $shellApp.NameSpace("full_path_to_zip_file")
$zipFile.Items() | Where { $_.Name -like "*.txt" } | foreach {
$_.InvokeVerb("Delete") }

Hey Adam thanks for responding and choosing to fool around with this one. If
specific file types can be found within zipped archives and deleted that's
good news. Crippleware like AutoCAD litters file systems with .bak files and
network admins will end up zipping many gigabytes of unwanted .bak files
because Autodesk software is GFS and can't be controlled using policies in
this context.

Can you confirm a method to delete the files within the zipped archive which
will also dismiss the dialog or circumvent the dialog altogether? Keeping my
fingers crossed on this one. The point is it will be costly to put a CAD
monkey at the keyboard just to dismiss dialog boxes so it would be right
back to square one for this task.
