I've really never messed with an external HD before. I transferred files from my HD to my external HD. I then deleted the files on the HD so I can free up space. Thinking I had the files on my external HD, since they were visibly there, I tried to open them up and all was lost/gone/no where to be found. How do I take apps/documents/music etc... from my HD to my external HD without losing everything? I hope I explained it correctly. Please help.
