La solution que j'ai retenu a été de programmer une interface conviviale me présentant toutes les données nécessaire pour que je réalise rapidement ce renommage.
Mon travail a donné ceci:
Pour réaliser cette interface, j'ai utilisé la bibliothéque graphique d'IBM: SWT ainsi qu'une bibliothèque de traitement des tags ID3 du format MP3: jaudiotagger.
Pour les icones utilisé, je les ai selectionné dans la librairie d'icone Human-O2 que j'ai trouvé ici.
Le logiciel requiert la présence de Java7 sur le poste, ainsi que VLC d'installé.
Ensuite j'ai rédigé le code suivant:
package com.marajy.mp3renamer;

import java.io.IOException;
import java.text.DecimalFormat;
