Yes, symlinks can be in a different file structure than their actual files on the hard disk. For example: ~/hyperscope/1/2/3/my-file.pdf may be in a complex structure of other documents, maybe in the same directory could be other 200 files, and file could be related to ABC subject. Same file in the public_html directory: ~/public_html/www.example.com/files/world/my-file.pdf then may give quite different context, different meaning in a different file structure. And even file name in WWW structure should may become more meaningful then the actual file name, that is matter of marketing online. Then I use often this command to give me the actual WWW link to the file provided file is in my public_html directory: (defun loc () "Locates the files, and if it is in public_html, it constructs the URL" (interactive) (let* ((files (dired-get-marked-files))) (kill-new (with-temp-buffer (while files (let* ((file (pop files)) (uri (if current-prefix-arg file (public-html-rest file)))) (insert uri "\n"))) (buffer-string))))) If the file is then located in WWW structure, I would do `M-x loc' on the file and get a result like: https://www.example.com.com/files/world/2020/04/foundation.pdf but if file is not located in WWW structure, I would get result like: ~/public_html/www.example.com/files/world/my-file.pdf -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
