Go to http://www.dropbox.com and set up an account. Once you’ve installed the application, you’ll have a folder
$HOME\Dropbox. Create a new folder
$HOME\Dropbox\config–this is where we’ll store all of our personalized configuration files.
You can store these configuration files in Github or Bitbucket–but that may be overkill for files that rarely, if ever, need to be merged. Dropbox stores prior versions of files–that should be good enough.
Create a folder for any application that you wish to configure. For example, create
$HOME\Dropbox\config\vim to store all of your
vim configuration files. When you move from machine to machine, you can symlink your
vim configuration files from your home folder to the corresponding files in your Dropbox folder.
$HOME/.vimrc -> $HOME/Dropbox/config/vim/.vimrc
