Duplicate copies of music files
I just bought a new Macbook Pro with OS X Yosemite, and have been transferring content from other computers.
I had a substantial music collection in iTunes on a Windows 7 system. To transfer it to the new Mac, I copied all the folders/files from MyMusic/iTunes on the Windows box onto an external hard drive, and then copied them onto the Mac under /Users/myname/Music/iTunes.
When I then started iTunes, all of my music appeared correctly. However, it now looks to me as though iTunes on the Mac has made a second copy of all of the music files. In addition to the folders/files I placed in /Users/myname/Music/iTunes, there is now another set under /Users/myname/Music/iTunes/iTunes Music.
So my question is this. I assume that the copy that iTunes for Mac wants is the set under /Users/myname/Music/iTunes/iTunes Music. Am I safe in deleting the folders/files I placed directly under /Users/myname/Music/iTunes?
