ce sont souvent des fichiers vides (taille zéro), j'ai un script pour 
les trouver. Attention, certains sont vides volontairement, leur liste 
peut être mise dans fichers-vides-normaux

#!/bin/bash
#trouver les fichiers vides
#(taille zéro), anormaux
#les fichiers normalement vides sont dans "fichers-vides-normaux"
#fonctionne à partir du répertoire courant

find  . -empty | grep -i -v -f ~/bin/fichiers-vides-normaux
