I've got a large file that happens to be stored in text (Adobe Illustrator), and every time I make even a tiny change the entire file gets previewed with green/red lines in SourceTree. It brings ST to a crawl for 20 seconds, while it goes line by line through the file for changes. I really don't need to see the file previewed at all, so is there any way to tell ST that I'm not interested in previewing or diffing the file? I would be happy to give up previewing on all files of type .ai if necessary.
This is on Mac, if it matters.
