I have started to get used to the idea of Wikilinks in Devonthink. Basically, there are an alias which can link to another file in your database so long as that alias name is exactly the same as the text.
For example, here are some of my notes and the underlined blue text are the Wikilinks.
Those underlined links will link to a specific file in Devonthink so long as its alias is exactly the same.
I click the link and the associated file appears:
The alias for this file is set in the information panel for that particular file:
I believe that more than 1 alias can be used for a file and it is separated by a comma or semicolon. I haven’t tried that yet.
The preference panel is where Wikilinks are turned off or on:
I am sure there are many ways to work with Devonthink and Wikilinks I have yet to discover, but this way seems to be working for me at the moment.
