Can I convert my org-mode wiki to org-wiki? And how can org-wiki access files in subfolder?

• MX-Linux 17
• Emacs 26.1.50 (graphical)
• init.el
• complete environment
• org-wiki configuration:

(require 'org-wiki)
(setq org-wiki-location-list
      '(
	"/~/orgwiki"  ;; First wiki (root directory) is the default.
	))
;; Initialize first org-wiki-directory or default org-wiki
(setq org-wiki-location (car org-wiki-location-list))

I have a wiki that I created using orgmode. I tried using org-wiki with it, but it cannot see the subdirectories, and only lists the files that are in the same dir as index.org. I also tried creating a new wiki, and put some files in there, and org-wiki could not see them. Does org-wiki support files in different places, or I should just put everything in the same folder?
