I'm a basic user but decided I really need to learn to use Swap Files. It used to be when I made a change to a song as long as I used the exact same title when importing the new version MS would replace the old one (or ask me if I wanted to) in all the setlists and collections that song was. Now it just adds a duplicate listing and I do it by hand, which gets rather tedious, and it's hard to remember all locations where that song exists.
So - Swap Files... I import my new version of an existing song. It shows up next to the old one. Long Press the new one, Menu, click "Swap File" where I expect to get a song list where I can choose the old song to swap out. But I just get a list of folders (I assume folders on my tablet) and don't know where to go from there. So I re-read the manual again but I can't figure out what I'm doing wrong. Any assistance would be appreciated. Thanks - Sue R.
