It's 50mb.
I've sent them a link to another site that serves a similar purpose, but I signed up for an account so you could reap the benefits of the referral. I've used dropbox before but think there's a limit and 50 mb is it. I'll poke around and see if he can send it to me, if I have trouble, I'll try other stuff. I may drive and simply get a cd from him. It's really important, so there's considerable time pressure.
