To the best of my knowledge, a Java *applet* can not read or write
any files on the client's hard disk. That's a security thing,
otherwise... Well I'm sure you can see the nasty security
implications of a webpage being able to read or write users'
files.... A Java application could do what you seek, but that can't
be embedded in a browser.
We ran into the same problem going in the oposite direction -- our
users want to batch download files from our site. We've started
implmenting it as an ActiveX component in VB. It's not cross
platform, or course, but as far as I know, it's the only way to
access users' file systems.
Best regards,
Zac Bedell
