Hi Patrick,

There is no limit. JCIFS should 60,000 files no problem.

Note that a ConnectionTimeout means that it couldn't even connect.
Meaning Java tried to create a TCP socket to the target server and it
just timed out. So this particular exception has little to do with
JCIFS. Sounds like your network is just cutting out from time to time.

Try increasing the connection timeout. Note that there are several
timeout properties. See the website release note for 1.3.17 about the
jcifs.smb.client.connTimeout property.
