note 1) Will not find volume label 
     2) This function does not support network operations 
     3) Wildcards are allowed in the filespec 
     4) If the attribute is zero, only ordinary files are found. If the volume  
	label bit is set, only volume labels will be found. Any other attribute 
	will return that attribute and all normal files together. 
     5) To look for everything except the volume label, set the hidden, system, 
	and subdirectory bits all to 1
