Box automatically keeps track of each version of a file that you save, making it easy for you to go back in time and view or restore previous drafts. This eliminates the need for you to save different versions of the same file with different names.
Once you’ve completed the upload, you’ll see a version icon next to the file name.
This icon shows you how many previous versions of the file are saved. If you click the icon, you’ll see the older versions, can download them or make an older version the most current one. It’s your very own time machine that’ll ensure you never lose your work.
