Get-Childitem -exclude

Altough a very basic problem, this still seems beyond me:

Get-ChildItem -Force -path d:\

Directory: D:\

Mode       LastWriteTime   Length         Name
----          -------------         ------            ---
d--hs       04.02.2013       11:48          $RECYCLE.BIN
d----        04.02.2013       12:53           f1
d----        04.02.2013       12:53           f2
d--hs       20.08.2012       13:40           System Volume Information
d----        04.02.2013       11:47           vImages

Everything as expected here. Now I want to exclude the directory "vImages"

Get-ChildItem -Force -path d:\ -exclude vImages

c:\_

Nothing gets returned. I could use the -path d:\* option with an asterisk but then it would display the contents of the folders, which is not what I want.

My question is, why does Get-ChildItem return nothing when used in conjunction with the exclude parameter?

Thanks for your help.
