Prior to thanksgiving, I had about 50 gigs of music on my harddrive. I recently visited my cousin and filled up the rest of my harddrive with his collection, with the intentions of just moving everything over to the external. Upon doing this, I've come into a data redundancy problem. I'm not sure if theres such a program to attempt at resolving these issues, but damnit i sure hope there is.
If not, I guess my next step would be separating the collections and attempting to transfer my original coll over first, hopefully not encountering any errors on the way.

The major pitfall here is now I've got a full harddrive, 80 gigs of solid, anally organized music, and no-way to get them transferred elsewhere.

Any ideas?
