O~ bug? Maybe~

There have been no files in the filegroup, in other words, the filegroup that i want to delete is empty.

BUt unfortunately, I can't remove it and still say:

"Msg 5042, Level 16, State 12, Line 1

The filegroup 'fg1' cannot be removed because it is not empty."

I also try to follow Bimal's steps, but it can't work.

Thanks all the same!
