Vim: Close All Buffers But This One

Question

How can I close all buffers in Vim except the one I am currently editing?

Answer 1

Building on juananruiz's answer.

Make a small change in the buffer you want to keep, then

:1,1000bd

The command bd (buffer delete) will not delete any buffers with unsaved changes. This way you can keep the current (changed) file in the buffer list.

Edit: Please notice that this will also delete your NERDTreeBuffer. You can get it back with :NERDTree
