This root folder becomes a child folder ofthe FILESTREAM share on the SQL Server host. By default, the name of the file share isMSSQLSERVER (or the SQL Server instance name, if you use named instances).The root folder must be unique across all databases in the same instance, and can beconfigured from SSMS or using T-SQL. Using SSMS, simply right-click on the database'snode in Object Explorer and click Properties and then, in the Database Properties dialogbox, go to the Options page, locate the FILESTREAM Directory Name option and typein the folder name.Listing 11-5 shows how to set the root folder using a T-SQL script. Note that thefolder name can be different from the database name, but it must be a valid Windowsfolder name.-- Configure the root folderALTER DATABASE NorthPole SET FILESTREAM (DIRECTORY_NAME = 'NorthPole')Listing 11-5:Set the FileTable root folder name using T-SQL.This method can also be used to change the name of the root folder, if previously set.
