What are t75__0_0_9000.fsh and t212_0_0_?.fsh ???

[bullddoo]

This question surely will be odd for a numbers here but I wonder know what are the t75__0_0_9000.fsh until t75__0_0_9999.fsh?
There is 1000 files in the zdata which was kits but which do not correspond has any team in the game.
In fact, I want to delete files in zdata_?? .big to make the fifa.fat smaller, and this kind of file come to disturb me!

I have two assumptions:
- this files are done for the creation of personnals team in the game.
- this files are useful for the GK kits which are not in the zdatas.

First, I can delete the file of my zdatas and, the second case, I wonder how the GK kit are allowed to a team which does not have any by défault,
In order not to have for exemple In the England football league 2, a missing texture on the Body of the GK when I play!

and i have the same quetion for the t212_0_0_?.fsh (? is for the team id), how the game use this files!!

Can you explain me, what are this files and say me what are the use of them?

Thanks for the future replies


edit : Anybody can answer me????
