The whole pack should be around 4.5 GBs large. Please note that couple dozen of demos were corrupted for unknown reason so I couldn't upload them.
EDIT: I didn't sorted out or go through anything, just uploaded the stuff that were on PCs after grand final. Since we needed to load new Windows on some computers during the event, some demos are gone thanks to that as well. Would still say there's like 70% of demos here.
