Como posso percorrer todos os arquivos em uma pasta usando o TSQL?

CREATE TABLE #tmp(excelFileName VARCHAR(100));
INSERT INTO #tmp
EXEC xp_cmdshell 'dir /B c:\my\folder\path\';

declare @fileName varchar(100)

While (Select Count(*) From #tmp where excelFileName is not null) > 0
Begin

    Select Top 1 @fileName = excelFileName From #tmp

    -- OPENROWSET processing goes here, using @fileName to identify which file to use

    Delete from #tmp Where excelFileName = @FileName

End

DROP TABLE #tmp
