I have a "file name.txt" file whose full path is "G:/path1/[TAG] path2/file name.txt"
How do I write the link to the external file "file name.txt" in org-mode?
If I use [[file:G:/path1/[TAG] path2/file name.txt][link]] it doesn't work
As mentioned in section 4.1 of the manual, you'd need to escape paths with square brackets. Try
[[file:G:/path1/\[TAG\] path2/file name.txt][link]] To make link creation/editing easier, look into M-x org-insert-link (bound to C-c C-l by default.
