That depends.
It depends on the Windows Explorer settings on the client. I forget
the exact name of the setting involved, but the default is to create a
file in the directory called Thumbs.db which - amazingly enough -
contains those thumbnails. If you turn the parameter off then things
get a little more intense when you visit the directory.

That helps. So just to clarify, if there is a thumbs.db file, it just
reads that for the thumbnail info for all files in that dir?

Also, for full text searches over CIFS, I suspect explorer will have
to haul each file down and perform the search locally as opposed to
creating some sort of index on the directory right?

Thanks

Well, this is stuff I have observed so it may be wrong but:
- I would expect the Thumbs.db to be updated if files have been added/
removed since it was last updated, possibls even if files have been
changed (if implementing this myself I would only do that on a
'Refresh')
- Unless the smb protocol offers a 'search all files for this string
on your local drive' command to the server, you should be right.
If your Samba Server runs something like xosview, I would try
searching a large directory and see if the network traffic suddenly
jumps. Running smbstatus could also tell you something.
