The VG Resource

Hey all.
I've got a question, an important one. What's the best way to batch convert a bunch of .dds to .png while keeping transparency? I decided to give XnView a go, but the backgrounds turn black, so that's no good. Any other suggestions?
And while were at it, I also have some .tga to convert too, but not nearly as much.

Edit: Know what awesome program I already had installed that works like a charm? SageThumbs, and it uses XnView's library too!
If you know any other methods or programs, feel free to also suggestion them below still.

Noesis works like a charm, and there's even a recursive option to convert all subfolders, too. Just be sure to change the "Output path" to the following to remove the redundancy:

Oooh, nice! I didn't realize Noesis worked for textures as I've always used it for models.
