蓝光BLU-RAY光盘目录结构如下：

Folder(1) = "\BDMV"
Folder(2) = "\BDMV\AUXDATA"
Folder(3) = "\BDMV\BACKUP"
Folder(4) = "\BDMV\BACKUP\BDJO"
Folder(5) = "\BDMV\BACKUP\CLIPINF"
Folder(6) = "\BDMV\BACKUP\JAR"
Folder(7) = "\BDMV\BACKUP\PLAYLIST"
Folder(8) = "\BDMV\BDJO"
Folder(9) = "\BDMV\CLIPINF"
Folder(10) = "\BDMV\JAR"
Folder(11) = "\BDMV\META"
Folder(12) = "\BDMV\PLAYLIST"
Folder(13) = "\BDMV\STREAM"
Folder(14) = "\CERTIFICATE"
Folder(15) = "\CERTIFICATE\BACKUP"

也就是说，完整的蓝光BD目录结构应该包括：

BDMV

　　AUXDATA

　　BACKUP / BDJO，CLIPINF，JAR，PLAYLIST

　　BDJO

　　CLIPINF

　　JAR

　　META

　　PLAYLIST

　　STREAM

　　CERTIFICATE  / BACKUP
