I had previously used a JBOD array of 3 hard disks to create a single volume in which to store all my music and videos. To make a long story short, I'm no longer using this JBOD array.
I still want to store my music and videos on these three drives, but when I use Media Player to add to the library, I only want to be able to specify one folder, but the scan must go across all three drives (drives H:, I: & J

.
I want to store my primary library in "H:\Media", and have junction points directing to "I:\Music (Secondary)" and "J:\Videos".
It is my understanding that Junction Points can help. The question is, how to create a Junction Point?
