I have a problem opening my mp4 files on my usb which I recently copied from my nephew's desktop. Originally, the files have an extension .mp4 but when I plug it on my own desktop, the extension became .m4a and I can no longer open the file. I made disk scan (on my USB) and found no virus. Can anyone help me solve this thing? Thank you very much!

M4A files can be opened with Windows Media Player, and very likely some other popular media player applications as well.

Were these files were copy protected music download from Apple?
