Denis Kozlov nous propose sur son site plusieurs petits logiciels très pratiques et de qualité.
J'utilise régulièrement sous XP et Vista:
ReNamer: pour renommer des fichiers en masse.
Shutter: pour éteindre/mettre en veille... automatiquement son ordianteur
Et trois autres petits logiciels: CPUMon, Hasher et Hooker.
Vous découvrirez les détails de tous ces freeware sur le site de l'auteur à cette adresse : den4b.com

J'utilise également ReNamer depuis longtemps et c'est une perle.
La visualisation des changements avant de les appliquer est très pratique.
A noter qu'il est portable pour ceux que ça intéresse.
Pour les autres softs, je ne sait pas, mais il y a de bonnes chances que ce soit pareil. D'ailleurs, tous sont proposés avec et sans installeur.
