The folder named “FHHD For v1.16” is a separate folder that goes to your Local Disk C - “Dysk Lokalny (:C)”
Other files from the ZIP “High, Low and Medium Settings” are separate files, which you save somewhere on your computer, like Desktop and then you can use one of these in your “FHHD For v1.16” folder for shaders.
They basically show how your in-game shaders mode will look like.
“How to replace shaders:
Open the file of the shaders you want and copy and replace ALL files to the main ''FHD For v1.16'' folder.”
”If you have older or laggy computer, I suggest using Low or Medium Settings.”
