    Description

      FileUtils.sizeOfDirectoryAsBigInteger can overflow.

      This is because it calls FileUtils.sizeOf(file) which calls sizeOfDirectory() for processing subdirectories.

      As it stands, the method only works properly at the top level.

      A possible solution would be to create private "Big" versions of the called methods; these would not need all the checks so should be faster.
