How can I use .fx shader files ?

If you want to use a shader, you have always to give a pixel and a vertexshaderfile to the engine. My question is:
Is it possible to use .fx files, although there is only one file than two?

I think you've got to use either hlsl or glsl shaders, depending one whether you're running with DX or OGL. So if you wanted to use fx you'd have to convert it.

Yes, CG is a pretty good shading language (nvidia) and is very similar to hlsl.

How can I convert .fx files to vertex and pixelshaderfiles ?

I'm not sure how .fx files work but aren't they just one file with both the shaders inside?

I'm pretty new to shaders, but aren't .fx files written in HLSL? Every hlsl demo I've found gives me a .fx file. This is the equivalent of .hlsl?

Nope, fx files (can) contain more than just shader code, for example defining what texture to use, or that the texture used should be clamped. Its like hlsl + nifty shortcuts. sortof.
