Unused File Group

Each database can have one or more File Groups, each with one or more files in them. Each database object (tables, indexes) is assigned to a file group. If a filegroup doesn't have any objects assigned to it, the files in that filegroup won't be used.

Suggested Action

Drop the empty filegroup to release any space used by it.

Any suggestion from Aireforge should be thoroughly tested before being implemented into production.
