Nope. It scans the directory.

You bet! It breaks software all over the place.

Could be. Hmm. The filter expression is looking for .zip files
(lowercase). As far as I remember WinXX *stores* the mixed case name,
but for most purposes it ignores case, but Explorer et al. downcases
all but the first letter for display. Suppose filtering works
on the mixed case filename and yours is really .ZIP not .zip...
