All what you perfectly discribes was in my mind when talked about file path benefits 
.
Thank you very much for these detailed explanation.
But there is still the question for more or less detailed level. We talking generally about low - normal - high resolution. But if we need a low-low resolution or a high-high resolution, what can be done?
Now after reading your suggestion it seems to be easy
If the resolution of ldraw/p/8 is still too high, just search for a lower number in the path! (f.e. ldraw/p/4)
That's it.
