Hi All,

  On further analysis, as to why the function deleteAgedDir is not 
getting executed, found that if this function finds a folder to 
be deleted then it should delete the 
folder(rmdirRecurse(dirname)), but in this case it does not 
delete the folder if it finds so the return of this function is 
empty, if there are no file to be deleted then this function 
works perfectly but if there is any folder preset to be deleted 
this that folder is not getting deleted, so i am suspecting that 
the issue is with the function rmdirRecurse is not working as 
expected on Windows 2007, so request your help on this please.
