Ok so the question might be a bit vague but this is to all the superusers of Dropbox.
I have an android phone, a Macbook, and a Windows desktop. I usually start my homework, coding, or themes on my computer and then I email or save the stuff on evernote and download it on my other device. Mostly between the mac and pc but I realized that I can use dropbox for seamless syncs to each device.
Let's say: I set up a folder called "theme-x" and I write some code for it on one computer and it syncs to my computer. Now if I edit the file on computer-2, will my files be replaced on all other devices? And is there a way to go back on the files? I haven't used any services like dropbox before so that's why I'm asking.
