Reply to How to easily search/organize music in an external HDD?

Good day
I'm new here, so please go easy on me :P

So, i finally decided to purchase a new hdd, since my old 2-partition disk was getting a bit small for both djing and personal stuff.
And here i am, done a squeaky clean install of windows, optimized it, installed serato, now the only thing missing is...the music.

I have previously backed up my entire old hd to an external drive, so the music is there, the problem is that i've never really created a library for my music, so all of my tracks are scattered across various folders. (yeah i know, very very messy, but i searched throught itunes in serato, and virtualdj could search on the whole disk, so i didn't really believe about actually creating one)

So here goes the question: does a software that automatically searches/organizes tracks in a drive, detects and ignores duplucates, and copies them to another folder/drive exist?

And no, doing it manually is not a viable option, because the tracks are literally everywhere, of different formats, and there are quite a lot of duplicates..

Thank you very very much
