This used to work on the Base form I wrote to keep track of video files I have that are not in the IMDB database. Now it doesn’t. An example of the error Base shows me is: "“M:\Personal\Documentary\Iconic Leaders\Volume 2, Biography, Adolf Hitler- The Rise to Power, 1961.mp4"” cannot be passed to an external application to open it (e.g., it might not be an absolute URL, or might denote no existing file).
The pathway certainly exists on the PC I am using and I tested it using file explorer. What do I need to do to get Base to run files for me again via VLC?
