I'm looking for an x-file exporter for 3ds max7. I'm sure older versions of the dx sdk had one, but the february sdk has only one for maya. And on google I was unable to find one :(

Panda Xporter tool

You Max users have it a hell of alot easier than us Maya users for .x support. The computer I'm on right now has the December 2005 SDK and it includes the Max exporter. I'll have to double check at home, but I could have sworn the Feb 2006 had it as well.

type in 3ds max plugin in google search bar and goto the first one it has two in its database

Download the Extras for the DirectX SDK, that has the exporters in. I dont think there was an update to the extras from the Dec 2005 SDK release though. As for exporters Panda as suggested is very good and if you are more flexible on your formats there is also Flexporter which is now part of the nVidia SDK I think, and also a very nice system at Ease Production and then not forgetting the Collada system.
