Could be possible to not delete it?

I mean using a special value for this case, mark delete (using 0xe5 as
first character) but put for instance creation month to be egal to 15.

This entry will be therefore be keep and not overwritten by successive
file creation.

At least this solve the file deleted issue (not the rename issue unfortunatly)
