OBJ File is missing, all mtl files still there After I emptied my temp folder all my obj files are missing, only the mtl files remained  in my blender folder.  Does anyone have an idea what happened?

now added a screen shot showing that my obj files are exporting as 3D objects

thanks a lot!

It could be that you had some hard link to the files you deleted from the "temporary" folder... who knows why.

I just tried an export with standard parameters (below): I see an .obj and a .mtl file in a folder I created on my desktop...
