Modify .Gr2 Files?

Hello everyone, one quick question..
Can you edit the texture path of a .gr2 file? And if you can, how do you do it?


Example:
Modify from:
D:\ymir work\monster2\wild_dog\wild_dog.tga
TO
D:\ymir work\new_archive\wild_dog\wild_dog.tga.

Thanks in advance!

Only with 3DSMax7.

But how can I convert .gr2 files to a file witch can be opened with 3DSMax7? And then export it back to a .gr2 file, with the texture path changed? If you can point me to a Tutorial it would be great..
