Hello, Laurence. I too have a question: are you using an apple computer or a windows PC? I was surprised to discover (from this thread) how difficult file operations appear to be with the 380 connected to an apple computer. So the answer from my experience (I use windows) is that any of what you mention is very easy. On a windows PC I can copy any file from any location to any other with ease - from internal to micro SD. From micro SD to internal. From PC to internal to micro SD in the player to micro SD in the computer and to any other device connected to the PC or anywhere on the network. It really is that easy and, tbh, I was totally surprised that anyone would have problems achieving so simple an operation with the 380 connected to ANY computer. So, as I say, it appears to be down to what computer you are using (in my experience with windows and from reading this thread, anyway - I have no personal experience of any computer except Windows). A member who uses an apple computer would be more qualified to comment on using that machine with the 380. Hope that helps.
