I have a following doubts which I don't understands why I can't see any tables belongs to filegroup below, see a file below file which having 190GB of used data space but couldn't find it at any table level.

name             fileid filename               filegroup  size               maxsize            growth             usage    
----------------------- ---------------------- ----------------------------- ------------------ ------------------ ---------
ChartBLOBS      3      C:\ChartBLOBS3.ndf     BLOBS      198433024 KB        Unlimited          1024 KB            data only

select * from sys.filegroups

name        data_space_id type type_desc      
----------- ------------- ---- ----------------
PRIMARY     1             FG   ROWS_FILEGROUP  
BLOBS       2             FG   ROWS_FILEGROUP  
INDEXES     3             FG   ROWS_FILEGROUP  

(4 row(s) affected)

I looked at sys.indexes but return me with 0 results

select distinct data_space_id from sys.indexes where data_space_id=2


(0 row(s) affected)

so how do I determine where is the data came from ?
