Im downloading a huge file (12.7 gb) and it is at 78% if i were to restart my cpu would i have to re-downlaod all of this or will it resume from 78%?
pressuming the file didn't get corrupted & you didn't remove the .torrent file you were downloading from, the download will resume from where you left off
That's the good thing about torrents. Also, sometimes you may find on some torrents, that when you close and reopen uTorrent, some of the torrent that you have downloaded goes down a few percentages or so. Also, if you move the file that you're downloading but haven't downloaded yet (even if you haven't finished a download on uTorrent, the place you saved the file in will have the file), just pause and start the torrent again, which should allow it to write to the original file.
