ETW-SFE: what is disk two actually for?

[Furunculus]

C was formatted, and i deleted the contents of my games partition because most of would need reinstalling these days anyway, gone are the days of re-linking the exe shortcut.

disk two does indeed appear to have data files, but the utterly ridiculous, stupid, unnecessary and cretinous steam installer does not seem interested, instead it is telling me that updating will be complete in 1.5 days!

i cannot help myself from expressing disgust that steam was ever made a core part of the install process.

i have even tried uninstalling the game and starting again, only for the same thing to happen again.

the install doesn't even ask me WHERE i want to put the game, steam just decides all these questions for me and makes a balls-up in doing so.
