The Art Of Not Asking Why

Denote includes the option of adding different directories, so this now makes sense:

(setq denote-directory
      (if (eq system-type 'gnu/linux)          ; If I'm using Linux, include the private folder.
          (list (expand-file-name "~/Sync/Notes")
                (expand-file-name "~/Documents/private"))
        (list (expand-file-name "~/Sync/Notes")))) ; If I'm using anything else (macOS) just Notes.

(setq denote-excluded-directories-regexp "data") ; the data folder (with attachments) is excluded.

I have a private folder for Denote notes on Linux only. I used to only sync my Sync/Notes folder, which includes my informational notes and blog posts, but that means I’m missing out on Denote’s abilities in my private folder, which is slowly increasing in size. This solves this problem.

There’s no need to list the data folder (which includes my attachments, mostly in file formats that are not Denote’s format), so that’s why the exclusion is there.
