Get Help & Advice on Installing & Using Karaoke Software by Power Karaoke

I have 160,000 songs in the database. Obviously I have duplicates. Is there a way for the duplicates to be shown separately? Or must I do this manually using search? This would be just so I could reduce the size of the songbook. Even better would be a way to have an iPad synch with the database so singers can search on their own instead of always asking me to look up a song as its impossible to print 1900 page songbooks.
Any suggestions?

What program are you using?

I've always just used excel. I was just wondering if there was a way to show all the duplicates at once so I could just delete the double entry's. excel would take a lifetime.

not if you use it in office 10 it has a dup file finder in it.
