vga Question Intel® Arc™ Graphics Windows* DCH Driver 3x Series (WDDM 3.0 & WDDM 3.1)

Can anyone enlighten me about the use & difference between these three types of driver folders/INF that are present inside the Intel DCH Graphics Driver?

Apart from the main DCH Graphics driver INF files (iigd_dch.inf, iigd_dch_d.inf & igcc_dch.inf etc), are these following driver folder / INF files really required when installing the driver or can be ignored & delete safely? 

CtaChildDriver [CtaChildDriver.inf]
I2CDriver [Intel_NF_I2C_Child.inf]
MiniCtaDriver [MiniCtaDriver.inf]

I2C driver is for Xe-HPG Graphic part to communicate with SMBus.
CTA drivers are for support custom resolution and act as a driver node.

If you don't have the corresponding vendor and product IDs in your system, then your graphic card don't support this, so no nned to install.

Thanks TOM, any info about the remaining Fw & Oprom folders? So that I can decide whether to keep or delete those as well.

These are firmware files for the first generation of the DG1 model, before the ARC came out.
I believe these are the same in every release of a driver.
