"i'm new with keil could you tell me please what's this header file path"
It's not special to Keil; every toolchain needs some way to know where to find files referenced by #include - this is commonly known as the "Include Path" or "Search Path" or similar.
The specific details vary according to the particular tool - so you must learn to study the manuals
For Keil:
