----------------------------------------
Hi [~jojochuang] , right, we can improve the log further with this. I think we
should only log if we failed to parse the "Current" format, and fallback for
parsing the old format (I suppose it is a rare occasion). We can extend the
present "unexpected" log,stating that we failed to parse both format, so we do
not expect the directory in the .trash root. What about that solution?
