VFP6 I have code to delete all the files in a folder greater than some number of days ago. But I also want to delete the folders that were created > than some number of days ago. How to do?

arraynum=ADIR(aTemps,ctables)
FOR i = 1 TO arraynum
   if atemps(i,3)+20 < DATE()	&& last modified date was over 20 days ago
	   cFile=aTemps(i,1)
	   DELETE FILE (cpath+cFile)
   endif	
ENDFOR
