Finding the CS:GO config file can be a bit tricky since it’s hidden in a different location depending on your operating system. Here’s a quick guide on where to find it.
What Are the Usage of Configuration Files
Configuration files may seem complicated, but they are not. It consists solely of a list of the parameters you want your game to use–from basic features like keybinds and sensitivity to more sophisticated ones.
But why are configurations used by players? There are several reasons:
Additionally, since many professional players make their configurations  public, it makes it simple to mimic their settings. You can download a player’s settings and fine-tune them if you think they might work best for your playing style.
Where is the CS:GO Configuration File Located?
Your configuration file may be found in two places. One is in the Steam folder, while the other is in the folder specifically for Counter-Strike: Global Offensive.
The first one allows you to change configs for each individual Steam account you might have on your PC. The path to the config file folder should look something like this:
C:\Program Files (x86)\Steam\userdata\XXXXXX\730\local\cfg
XXXXXX should be your Steam ID. If you only use one Steam account on your PC there will only be one folder. You must be aware of your Steam ID if you have multiple ones.
You can do so by going to Profile-Inventory-Trade Offers-Who can send me Trade Offers? and then looking for your trade URL. Your Steam ID is a series of digits that appear in the URL.
You can choose the appropriate folder to access your configurations after you have your Steam ID.
