I use the menu - shortcut is
Alt v; i; k - this sorts items into track order. But if trak isn't one of the items selected for display, it doesn't work. In the menu below where the i is called, there's an option for choosing the details, which provides a drop down menu for everything under the sun, and you pick as many of those as you need (I expect there's a limit).
At present, my external hard drive is defined as pictures but it's displaying music details like track number. My C: drive - the main system disk in the computer - is defined as a music folder and this CAN'T be changed. Except it does, from time to time.
I don't understand it. I mean, it's not a problem, just a pain in the arse, y'know?
