I tested dupeguru but it's for files in general, and the Luni's toolbox is specific for images. I think with this I'm fine, the work can be done easily with this portable and free software and with the notepad++ in a few minutes. The only thing I need now is the texture dumps for both PAL & NTSC dragon quest. Or any other game, like the Tales of the abyss.ahh i undertsand wrong. question: dupeguru has some function to do some what you need? i only use it for find duplicates by name, maybe have another functions.
Thanks for your help : )
