# FileFrontEnd
## Configuration
### Technologies utilisées
* Java 11 (ressources informatiques)
* Gradle 7.1
### Projet
* src > main > resources > appdata.json -> Fichier de configuration à modifier
* storagePath : indiquer le dossier où les fichiers temporaires du FFE seront stockés
* network_interface : indiquer l'interface réseau à utiliser. Si elle n'est pas bonne, le programme demande laquelle utiliser au démarrage
