Here are my new mime types, based on the new icon theme Sphere 1.4. In the new icon theme are indeed already mimeTypes in it, but these are still not as I want them look like. You can use it in any linux theme, maybe you have to check the index file. In Sphere 1.4 they will immediately work.

All users of Sphere 1.4 v2 please wait for the next update, there are these mimeTypes included anyway.

There are more than 3400 icons (included ln-s links) in sizes from 16x16 to 24x24 in a simpler design for better representation and 32x32 - 255x255 in high definition. In addition, a scalable folder with svg files for the particular representations.
