If i recall correctly, with FTP, the file is copied into the directory,
but it is not "ready" for use... I have an application that reads the
contents of a FTP directory, looking for files there... i've never had
any issues where it only got a part of the file (that i know of
anyways)... maybe the samba does the same thing?

how large are these files (or how large would the largest file typically
be) ?   would it be worth looking at the "time" of the file, and waiting
until that file is at least (say) 5 mintues old, then do something with
it?  if it only takes < 1 minute to put these files on teh share, then
maybe you can reduce that time... 

Just thinking of alternatives...
