Thanks for your update. I did a complete deletion of all songs and did a new import without having the copy to the media folder and that solved the storage problem Thanks!
For example it will find the same titles by the same artist but the songs are either a different version or the same version on different albums such as original album and also on greatest hits. It would be nice to be able to filter out some of the results upfronts. Overall I am pleased and will continue to tweak my music thanks for your time.
Glad you got what you wanted. The exact match option should find the true duplicates and turning on additional columns of information can help you identify different versions.
