1) You are right. I think you need a thread to do the file processing.
I would suggest that the "start" button or whatever create the thread.
Threading is an interesting game, but well worth the effort.

2) Richard is right. Although I have not looked hard at Applets, I
believe that as a security measure, they are not allowed to access the
local drives. I believe they are only allowed to read/write files that
reside on the server from which the applet was downloaded. Not, I think,
what you're looking for.

Applications (run from the local drives as opposed to in a browser) have
none of the applet restrictions, and can access/scramble your hard disk.
