Here is a very small script to list the file names in a folder using SQL Server.

The below snippet has been useful for us to automate the restore process from a defined path(for large number of backup files).

/**********************************************************************/
	DECLARE @COMMANDSHELL TABLE ( LINE VARCHAR(512)) 
	DECLARE  @CMD VARCHAR(512) ,@BACKUPFILEPATH NVARCHAR(256)
	SET @BACKUPFILEPATH = 'D:\DATABASES\BACKUPS\' 
	SET @CMD = 'DIR /B ' + @BACKUPFILEPATH +  ' /TC' 
				
	INSERT INTO @COMMANDSHELL EXEC MASTER..XP_CMDSHELL   @CMD 

	--Data Clean up 
	DELETE FROM   @COMMANDSHELL WHERE  LINE IS NULL

	SELECT* FROM @COMMANDSHELL A
/**********************************************************************/

Prerequisites: You may need to enable the xp_cmdshell using sp_configure as below:

--To Enable the advanced Options
EXEC SP_CONFIGURE 'SHOW ADVANCED OPTIONS',1
RECONFIGURE WITH OVERRIDE

--To Enable XP_CmdShell 
EXEC SP_CONFIGURE 'XP_CMDSHELL',1
RECONFIGURE WITH OVERRIDE

--To Disable the advanced Options(by default)
EXEC SP_CONFIGURE 'SHOW ADVANCED OPTIONS',0
RECONFIGURE WITH OVERRIDE
