Hey Vikki,
Yeah, the collaboration feature seems like it would be a good option here, but obviously only if you were able to get things to work and do the process to complete in a reasonable amount of time. 7GB is probably a 6-10 hour process even with access to an unrestricted high speed connection. I think even with the speed set to 100% in the Creative Cloud app preferences, it still limits the bandwidth usage so it doesn't interfere with normal internet use. Honestly I'm at a loss for any good alternatives. It might be worth testing with another file sharing services to see if you have the same issues there too. I've asked a few others that work more exclusively with InDesign and will pass on any suggestions they have that might help if they do.
