Those are Windows 2000 "alternate data streams". They're very rarely
used, and Samba doesn't support them. The way ADS's are accessed on the
Windows side is something like "filename:stream" so you just end up with
ugly files when something tries to write them to a Samba share. I've
heard of some graphics browsers that keep extra information in alternate
data streams, but I don't remember which one it was.
Check the archives of the Samba mailing lists, it's been discussed some
there. I think the general consensus was that there wasn't really a good
way to store them and there were much more important things to work on.
