Is there a program to find duplicated yamaha styles ?

Dear forum members.
I have gathered by the years a lot of yamaha styles which I am using for my yamaha 9000 pro .
My collection is so big , that I am afraid that there are many duplicates on it .
My question is : does anybody knows a program to import yamaha styles for to find duplicates and to have the possibility to delete them ?
Important is that that program can read the typical structure of the extension of the yamaha style [ .sty]
so to find duplicates on base of name , date or size is no solution for I changed the names and date of those styles for my own private collection .
therefore I need a program that read those files specially on base of the typical .sty of yamaha .[ like “bbfinder” for band in a box files ]
Please , who can advice me ?
