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 and not using the vim GUI(gVim).

I looked at this post and added the following lines in my _vimrc

set backup
set backupdir = D:\\VimTemp

I have already created D:\VimTemp on my system.

Now whenever I try to save changes to my file using :w I get the following error message

"PenProperties.py" E510: Can't make backup file (add ! to override)

I have already tried setting the backupdir in the following ways:

• set backupdir = D:\\VimTemp

• set backupdir = "D:\\VimTemp"

• set backupdir = "D:\\VimTemp\\"

• set backupdir = "D:\VimTemp"

Now, I have already looked at similar questions on stackoverflow but the problem is still there.

So, my question is how to make this work properly.

Answer 1

Kill the spaces around =

set backupdir=D:\\VimTemp

should work if you've created the directory.
