RE: How to make Windows display the storage size and free space correctly

I have modified my mod_dav to support quota-available-bytes and quota-used-bytes, but Windows (XP and Vista) still does not show the correct size information.
Does anyone know whether Mini-Redirector (WebDAV client of Windows) support these two properties of WebDAV.
