I'm currently at university, but i need to reformat my computer, unfortunately i don't have my sc2 disk with me, is there any way to 'back up' the game, so that i dont have to download the entire thing (as i think my university will complain about the Internet usage).
I have an external drive, but i have a feeling just copying the c:/program files wont work...
It will, copy all the game files and simply start the game after reformatting. The game doesn't need any register entries or documents to start. U can also copy documents SC2 folder to save your settings if that is essential. Been changing operational systems plus from pc to notebook many times now with no re-installing of the game.
Are you sure about that? I recall from WC3 that while it did not need any registry settings to run the game, bnet updater would not run if those registry settings were not present.
To be sure I'd dump the relevant registry tree (should be somewhere in HKLM\software\blizzard, but just search for "starcraft" or "blizzard"), save the program file and also save the Documents\Starcraft II folder in your user directory.
I am not sure, but replays might be saved in some other windows application data folder
