Erasing MacBook Air
I had to stop in the middle of the erasing process. Now when I turn it on, all I see after the apple logo is a file folder with a ? in the middle of it flashing. What to do?

Are you booting to Recovery? If you are starting up normally then it is trying to boot to your partially erased volume and obviously cannot since it is partially wiped.
About macOS Recovery - https://support.apple.com/HT201314 - "OS X Lion and later include OS X Recovery. This feature includes all of the tools you need to reinstall OS X, repair your disk, and even restore from a Time Machine backup." - Also information about Internet recovery.
