Custom Properties in File Explorer

We can't have the custom properties in the file explorer (Solidworks 2011) with Windows 7 64bits

Some users have Windows XP and the properties are showed at the screen.

You could be simple if we could add a custom property to the Windows explorer but

i can just add the column Description.
