The progress bar should definitly update more often. But making it happen on a file basis won't change much as it's one specific step which take much of the time for each game. So it will still update slowly by doing it file based.

As for now, I see 2 solutions:

• Better integration with GDITools. Maybe converting it in C#code, so I can know precisely what it is doing and update the progress bar accordingly. I really want that in the future, but it's not my priority.
• Make an estimate and improve after each game copy. But it will be useful only in case we copy several games. I think I will try to work on this one soon.
