German,Do you need to alter the batch file according to something in the wiki, or is it fixed?
The best way I have found for local access on my Windows 10 is using TiddlyDesktop. Of course this access is only to the local machine not that of the node server (if they are different). TiddlyDesktop can access and host (not tested by me) both file and folder (node) based wikis.
Bob (even bob.exe) also permits the issuing of commands to the operating system, in this case it could be on the separate server but not locally (unless they are the same thing).
If, as implied by your brief description, you want a Windows computer serving the the wiki, to execute the batch on the server when the user is not on the server, Bob seems to be the only full tiddlywiki solution with appropriate messaging -
However as long as the wiki can generate a trigger, that the server can identify then respond to, such as saving a tiddler with a known file name. Then you can write a server process to respond to the trigger.
I have in the past, as have others, written what I call a sentinel batch that you run on the server that monitors for the existence of a file and if it exists runs a preset batch file.
If the batch can be run on the local machine, regardless of what happens on the server, such as in your example you could just give everyone a link on their computer to run that batch locally, and instructions in the wiki to do so.
