**  Creater:wuxiaofeng
**  Date:03-09-01 16:33
**  Maintain Date: 03-09-15  18:14
**  Modified: let COPY button gray at CF Card side
**  Maintain Date: 03-09-15  11:54
**  Modified: delete the wrong color define
**  Maintain Date: 03-09-17  15:36
**  Modified: if deleting the last file in card, then turn to CDROM side.
