Need to merge folders and data without losing files.

Hello,

I am new to this forum, but have been listening to merlin and reading for a long time. I will get right to the problem.

My data is a mess. I have a 500gb external drive bulging at the seams with duplicate files and folders. The problem occurred because my wife and I both backup to this drive. We now have our own folders full of the same files(mostly music). Now bear with me. I hope this doesn’t get too complicated.

At the moment I have a drive that looks similar to this

z:\my music\joe smith\track a, b, c, d etc.

z:\her music\joe smith\track a

i need to find an app or script or something that will allow me to merge both joe smith folders combining the tracks without deleting.

Anybody know of a way to do that?

Any help would be greatly appreciated. My hard drive is getting full, and I am not looking forward to fixing this problem by hand.

Thanks
