Appalling- folders view divided by artist only

I have no way of accessing my folders, which were divided by format and bit rates. This work took weeks of my time, and was the perfect set up. Suddenly, without being asked or warned, all my folders are gone, and I have just a list of artists (even in the folders view). What kind of arrogance allows you to decide for me how I should be able to divide my music collection? If anyone knows of a better app, please let me know!!
