How to open a new file in gvim? E303: Unable to open swap file

Solution 1:

Solution 1

This seem to be a bug. From Vim E303: Unable to open swap file for "[No Name]", recovery impossible, I should add this to _gvimrc:

set directory=.,$TEMP

Solution 2

To clarify the location of files and directories, which aren't immediately obvious, here is another solution.

Make the following directories (e.g., from a command prompt):

mkdir %HOMEPATH%\vim\backup
mkdir %HOMEPATH%\vim\tmp

Note that %HOMEPATH% equals C:\Users\User.Name, where "User.Name" is your Windows user name.

Then copy the following into %HOMEPATH%\_vimrc:

set backup
set backupdir=$HOME\vim\backup
set directory=$HOME\vim\tmp
set nosmartindent
set tabstop=2
set shiftwidth=2
set expandtab
set ai
set pastetoggle=<F2>
syntax on

Save the file and the error should go away.
