EXTRACTION and ARCHIVING New option "Try to edit non explicitly supported file types" in Options > Settings > Archive manager: off by default in order to protect from modification files outside known supported extensions; if on, allows to try to add/update and remove files form files not usually employed as archives, but structurally based on archive types such as Java jar, MS Office and OOo files, etc
