What is the point of a version control system? Why don they just upload the source code to an FTP directory?
• Version control systems keep track of all the changes, when they were made and by who. If the developers later find out something they did was a mistake and broke something important they may have to rewrite it from scratch. With this they can just ‘checkout’ a revision from when it was working. It also allows the developers to add comments so they know what changes have been done.
