    NERDTree is trying to write the bookmark to “$HOME/.NERDTreeBookmarks” by default. This is how it looks like in the code:

    call s:initVariable("g:NERDTreeBookmarksFile", expand('$HOME') . '/.NERDTreeBookmarks')

    While it’s possible that you’ve set the “g:NERDTreeBookmarksFile” variable somewhere in the configuration, it’s a lot more likely that emacs has, for some reason, set your “HOME” environment variable to “C:\emacs\home”. This explains the slash/backslash mixup as well. You can try two things:

    • Change the $HOME variable to your home dir, “C:\Users\your-username”. A quick google turns up this guide for windows 7: http://www.itechtalk.com/thread3595.html
    • Just set the “g:NERDTreeBookmarksFile” variable to your home dir (“C:\Users\your-username”).

    I’d recommend the second option, since it’s definitely going to work. You may need to escape the backslashes and spaces, but I can’t be sure how at the moment. Try it out in all of these ways and see which one works for you:

    let g:NERDTreeBookmarksFile = "C:\Users\Your\ Username"
let g:NERDTreeBookmarksFile = "C:\\Users\\Your\ Username"
let g:NERDTreeBookmarksFile = 'C:\Users\Your Username'
