p>文件名是库ID（D989408F65D05F99）和轨道ID（EB5B7A9086F4B4D4）的汞合金。目录结构来自库ID，并且轨道ID的最后三位数转换为十进制，即4D4变为04,13,04。

The filenames are an amalgam of the library ID (D989408F65D05F99) and the track's ID (EB5B7A9086F4B4D4). The directory structure comes from the library ID and the last three digits of the track's ID converted to decimal, ie 4D4 becomes 04, 13, 04.
