use this.

SET @Path = 'C:\Software\';
DECLARE @cmdStr AS varchar(250);
SET @cmdStr = 'ERASE /Q /S '+@Path+'\*.bak'
EXEC master..xp_cmdshell @cmdStr, NO_OUTPUT

sorry forget to declare @Path variable, use this one.

DECLARE @Path VARCHAR(100)
SET @Path = 'C:\Software\';
DECLARE @cmdStr AS varchar(250);
SET @cmdStr = 'ERASE /Q /S '+@Path+'\*.bak'
EXEC master..xp_cmdshell @cmdStr, NO_OUTPUT

/Q means it will do its work quietly ;) generally when you manually delete it, than it ask for prompt want to delete it? yes or not, it won't ask anything.

/S will delete from sub directory also.
