How to change the folder path for swp files in Vim

I'm working at a project on a remote server. I don't want to have the swap files on the server. I would like all swap files for Vim (and, of course, gVim) to be saved on the specified directory. How could I do that?

You can set the directory option to the location that you want vim to store its swap files, e.g.:

 mkdir -p $HOME/.vim/swapfiles  # this dir must exist vi does not create it

" $HOME/.vimrc
:set directory=$HOME/.vim/swapfiles//

I use trailing double path separators because, from the help docs:

> For Unix and Win32, if a directory ends in two path separators "//" or "\", the swap file name will be built from the complete path to the file with all path separators substituted to percent '%' signs. This will ensure file name uniqueness in the preserve directory.

You might want to consider setting the backupdir options as well:

set backupdir=Z:\backups

That makes vim store backups in a specific location rather than in the current directory.
