This was some initial (mis?)-information about the case, but at least according to the Second Circuit:
> In addition to proprietary source code, Aleynikov
also transferred some open source software licensed for use
by the public that was mixed in with Goldman’s proprietary
code. However, a substantially greater number of the
uploaded files contained proprietary code than had open
source software.
Were the files source code or were they some sort of transaction logs, generated records, and what have you? Or were they various forks/branches of mostly the same thing intended for testing? If you don't know then you can't assess their relative "value".
