find copies but frezzes when almost done

seems like once its gets to the ending the bar stops but it keeps on finding copies and the file name doesnt change could it be that i have to much music for it to load because i am a dj and i have about 975 gb of music. idk but i would like to knw if there is a fix because thos program would help me a lot
