errors with filesystem operations

[Hugo Florentino]

Update: the combination of both your suggestions worked:

   if (exists(BlankDirToDelete))
   {
     try
       rmdir(`\\?\` ~ BlankDirToDelete);
     catch (FileException e)
       writeln(e.msg);
   }

Thanks! Now I just have to find out why the block of the file 
extensions is failing.
