Of course source control tools like Git, (Mercurial, SVN, etc...) can do a great job at managing source code. But I wonder, do these tools provide the developer with any advantage when used to store copies of files such as PhotoShop PSDs and Illustrator AI files? Does it make sense to use these tools with these kind of files? Would I be storing less in the repository than the sum of the file sizes of all of these files? Even though the file format of these files is only machine readable, I would expect that in for such applications, especially when dealing with vector rather than raster graphics, a small part of these files would change, and much of the rest would remain the same.
Thank you for your insight.
Although this is very opinionated issue, I would say no — at least for git.
I think that you're much better off with dropbox.
