Que vous ayez hérité d'anciennes archives ou que vous collaboriez avec des systèmes différents, notre outil vous permet de passer d'un format à l'autre avec aisance. Nous avons conçu cette interface pour être intuitive et rapide, vous garantissant une transition fluide de vos données, sans la complexité souvent associée à ces opérations. C'est une solution fiable pour maintenir l'accessibilité de vos informations, peu importe leur origine.

  • Archives cadastrales départementales
  • Données de recherche universitaire (phénoménologie)
  • Projets d'architecture (CAO/DAO)

Il est à noter qu'en France, Belgique et Suisse, le format ARJ a été historiquement utilisé pour certaines bases de données patrimoniales ou documents techniques avant la généralisation des formats ZIP ou 7z, rendant cette conversion particulièrement utile pour la rétro-compatibilité avec les systèmes actuels, souvent basés sur Linux pour les serveurs TGZ.
