OSX Invisible files

I am constantly taking my portable drive back and forth between osx and windows xp.

Is there some way to make opus NOT show the invisible files that OSX creates in every directory I access with it?

My drive is formatted FAT 32

Do the files / folders always have a certain name (or names which match a certain pattern), or do they have the Hidden attribute set?

If so then they are easily hidden via Folder Formats, on the Filters tab.
