Convert NBA to NBI

nba to nbi conversion is most likely searched by users of Nero BackitUp software that are trying to somehow export or recover these backups. It is most likely ot possible to convert one to another, you could perhaps recover the contents somehow and produce a new backup. In any case, only the original software will be of help here and no 3rd party products can help you. If you have issues with Nero files, it would be perhaps best to contact their support.
