How can I close all buffers in Vim except the one I am currently editing?
I like 1,100bd (suggested by juananruiz) which seems to work for me.
I added a quit! to my mapping to give me
nnoremap <leader>bd :1,100bd<CR>
nnoremap <leader>bdq :1,100bd<CR>:q!<CR>
This kills all the buffers and shuts down Vim, which is what I was looking for mostly.
I was able to do this pretty easily like this:
:%bd|e#
                                                                        If you don´t care the current one, is more simple to do something like (no script needing):
1,100bd
                                                                        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
You could use this script from vim.org:

Just put it to your .vim/plugin directory and then use :BufOnly command to close all buffers but the active one. You could also map it elsewhere you like in your .vimrc.

Here's what I do. So I like to keep my cursor position after removing all buffers and most of the solutions above just ignores this fact. I also think remapping the command is better than typing it so Here I use <leader>bd to remove all buffers and jump back to my original cursor position.
noremap <leader>bd :%bd\|e#\|bd#<cr>\|'"
%bd = delete all buffers.
e# = open the last buffer for editing (Which Is the buffer I'm working on).
bd# to delete the [No Name] buffer that gets created when you use %bd.
The pipe in between just does one command after another. You've gotta escape it though using \|
'" = keep my cursor position.
