I am trying to move _viminfo out of my home folder to make it simpler. So I added this to my _vimrc: set viminfo+=n~\\AppBackup\\Vim\\_viminfo However it's useless, Vim still create _viminfo in my home folder. Then I manually input the command above. This time it works fine, so I am sure the command itself is valid. How should I solve this problem for now? To be more specific, I am using GVim 7.4 on Windows 8.1.
