Joe: The problem could have been one of two things: 1. The root directory had too many files in it, or 2. If you're running the file through the Transfer program, you need 2 to 3 times the amount of space, and if you're conpressing it, then of course, it would take up additional space.

But the transfer failed because it ran out of space. Any help will be appreciated why this may have happened. Joe Lazzaro
