Before Drive, if you wanted to access files from different computers or devices, you typically had to make separate copies. Updating one copy meant you had to manually update all the other versions, too. Drive simplifies your work by automatically synchronizing the latest version of your file across the web and all your devices. After you store your files in Drive, you can reach them on any computer, smartphone, or tablet. When you change or delete a file stored in one location, Drive makes the same change everywhere else, so you don’t have to.
