Question

vi editor stores most of its information in a hidden swap file.

(a) True

(b) False

This question was posed to me in an interview for internship.

This intriguing question comes from Vi-Ex Mode in section The Vi Editor of Unix

Answer 1

The correct answer is (a) True

The best I can explain: Accidents can happen while working on a system like a system or power failure. To recover from these kinds of issues vi stores most of its information in a hidden swap file. This file is removed on a successful exit from vi but it remains on the disk if there is an improper shutdown or power failure.
