i do believe these are indeed the original files.
the files were created on 24 october 2000. (at least, that's what they say. i guess one could easily put a fake date on them.)
the question that remains: which were first? these .shn files, or that cd-r from the tree? what's the best version for our (hypothetical?) magnet link project?
or do they have an equal distance from the "source"?
were the .shn files used to burn the tree cd-rs? or were they also sourced by ripping another tree cd-r?
(when was this tree?)
