I tried deleting the files but I got a message the files cannot be dropped because its not empty. So, I did DBCC SHRINKFILE (RBSFilestreamFile, EMPTYFILE) and I got the following error message:
Msg 5509, Level 15, State 3, Line 1
The properties SIZE, MAXSIZE, or FILEGROWTH cannot be specified for the FILESTREAM data file 'RBSFilestreamFile'.
Do I have to manually go to the share and delete the files from there and then drop the file and filegroup?
