Select Save the home folder in a disk image and Click Delete User. Access System Preferences→Users & Groups, and Clock minus button on the bottom in the left panel. First of all, create a new admin account and login with this account. There is an easy way to backup each user account on your Mac. If you have more than one user on your Mac, and you’re only interested in backing up your own data, just go one level deeper and select your user account from within the Users folder. Each user account contains your Desktop files, documents, downloads, videos, music, and pictures. This will back up your user account, along with any other accounts on the Mac, plus any shared data. When choosing what to backup manually, most importantly look at the Users folder, located by default at Macintosh HD/Users/. So, If you skip this step, you won’t be able to recover your data if something goes wrong.

Note: A clean install of macOS Sierra on the startup drive completely erases all data on that drive including all your files (documents, music, movies, pictures, and even apps).
