I'm intending to backup the source files of a program I'm working on. So what I tried to do is left-click-->Make Alias with each of the source files and then moved the aliases to my DropBox folder on my computer. I assumed this would have the effect of having the source files being saved in my DropBox account as well as on my machine whenever I save my work. But the alias files have some weird encoding. Also, I just made a GitHub account and I'm wondering whether there's a way to use my GitHub client to automatically sync the most recent version of the project on my computer.
