How to organize projectile, image-dired, tramp temporary files

Question

I always try to keep my .emacs.d neat. So I put all the customization files into var folder.

So the question is how to let Emacs Know the default files of projectile, tramp and image-dired should go into my var folder? -- As shown in the figure.

Many thanks.

You might need to customize these files one by one yourself, for example, to put projectile-bookmarks.eld into your var/:

(defvar my-data-directory
  (expand-file-name "var/" user-emacs-directory))

(setq projectile-known-projects-file
      (expand-file-name "projectile-bookmarks.eld" my-data-directory))

I am not sure if all files you need is customizable.
