Bob (and the normal nodejs server) can serve media files, for the bob specific version the documentation is here: https://github.com/OokTech/TW5-Bob/blob/master/Documentation/Serving%20Files.tid or under the Bob tab in the control panel of your wiki.
If you have 50k tags spread out over 100 wikis there is probably no problem, if you have 50k tags in one wiki it may cause some slowdown because of how tags are cached, so you may want to use field values instead for some things, or check out the GenTags plugin so you can have multiple tag fields that are more specific than just 'tags' (https://ooktech.com/jed/ExampleWikis/GenericTagFields/) I have over 100 wikis served by Bob with thousands of tags between them and there is no problem. The repeated listing in the folding view is something I have run into but I couldn't find the cause of it, so until I do I can't fix it. I need more information about the situation when you say 'subwikis do not appear' to say anything useful about it. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
