Comment 1 for bug 893242

We have to consider the following use cases:
1. Changing of library location due to drive letter change or mount change
2. Changing library location configuration, without moving files.

The current solution is focused on 2. , the proposed solution is focused on 1.

If the Library folder location changes, Mixxx has to check if it was case 1. case 2. or something in between.
Today, Mixxx should already be able to detect moved files. Maybe we simply have to speed up this.
