Nope. You can't do it. Not yet anyway. In the future there will be these
additional methods addes to SmbFile:

SmbFile[] listSmbFiles()
SmbFile[] listSmbFiles( SmbFileFilter filter )
SmbFile[] listSmbFiles( SmbFilenameFilter filter )

They will be symmetric with the analogous methods of the
java.io.File class. And, yes it will be much much faster because
the TRANS2_FIND_FIRST2/NEXT2 listing operation returns all of this
information. The CIFS protocol also supportes primarive filters
(e.g. *.exe).

Surprisingly no one has brought it up, but it has been on my list for
a long time. I just wanted to get a really stable client out the door
first. I believe we've done that so it will be addresses during the
next iteration.

Yeah, you're definately better off with jCIFS in this case.
