How Big Are These Files?

I've been moving files to and from school a lot lately, and needed a bigger flash drive to hold everything.  Sometimes I need to change a video and it's great to have everything available all the time - project files, music and graphics, and finished flash-based videos.  Here's some sample sizes:

2:00 video (including folder of other "stuff" needed to post on the net) = 12 mb

Project folder of 2:00 video (all the files needed + the raw video clips) =  45 mb

The only thing you post to the server is the actual video and folder of flash files...so for this example I only need 12 mb of space for the 2:00 video.
