I may be an idiot, but what's the trick to the simple copy and paste operation in ubuntu? Each time that I reinstall a different system, I simply use my back-up drive to install my pictures, music and the rest into the correct folders. What is it that I don't get? This happens to be ver. 12.04, but I had the same problem in 12.10 and I removed it. With Mint...no problem. What changed?
