Nekuti format iri kutengesa kwavo kutumira wrapper, akazvimirira kune yake apps uye, yezvinyorwa zvakabhadharwa, kune yako account. That is what makes it convenient inside that ecosystem and awkward outside it. Files that are not account-locked convert normally; protected ones cannot be opened by any converter, which is a deliberate property of the format rather than a limitation here.
