So, I liked versions. The concept is great, I use it from time to time, but ever since iBooks Author came out, the versions files are destroying my harddrive. Before iBooks Author, the file was a couple hundred MB, something that I can handle. Even adding around 100MB a month would be fine. I downloaded and started messing with iBooks Author the day it came out. The only file I've really worked on is about 90MB right now, but the file that holds the versions for everything in the computer has ballooned to 4.6 GB. Last week it was only 3.5GB. I'm not going crazy changing the iBooks Author file. I edit it when I need to and I add Keynotes and only 2 movies (each less than 10MB) so I'm not really sure what's going on here. Anyone else have this problem and/or know how to fix it without losing the versions of everything else on the computer?
