Vim - Open several files at once

Last week I had to make changes to several files at once. In order to have all those files open at once in VIM I used this interesting approach described below, which I found in this Stackoverlfow question.

I grabbed the list of files and saved them to a files.txt file, each file must be in a new line and prefixed with e (edit) command:

e file1.js
e file2.js

Then in vim run:

:so files.txt

Each file will be open in a different buffer. Then, as changes have been done to each file, run :w|bd to save the current file, close the current buffer and move to the next buffer.
