Vim error E510: Can't make backup file (add ! to override)

Question

I am using Vim on Windows and decided to create a separate directory for all my backup files created by vim.

I am using Vim from my command prompt

Answer 1

On Linux, you can do by setting in editor- :verbose set backupdir?

Answer 2

Kill the spaces around =

set backupdir=D:\\VimTemp

should work if you've created the directory.
