Creating Directories for Users

So I want to create a directory when the form loads. But, the issue I'm going to have if another person uses said program is that their computer name is not going to be the same. I searched on the website [ https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/file-system/how-to-create-a-file-or-folder ] stuff but I couldn't find anything related to creating a directory on a general computer.. Code I have:

private void Form1_Load(object sender, EventArgs e)
{
    // A method for setting the colors and other settings.
    ColorAndSettings();

    // The path of the directory I want to create.
    string path = "C:\\Users\\Jay\\Documents\\FileEditor\\Saves";

    // A check to see if the directory does not exist.
    if (!Directory.Exists(path)) {
        // If it don't exist the create the directory at targeted path, set above.
        Directory.CreateDirectory(path);
    }
}

private void Form1_Load(object sender, EventArgs e)
{
    // A method for setting the colors and other settings.
    ColorAndSettings();

    // The path of the directory I want to create.
    string path = "C:\\Users\\Jay\\Documents\\FileEditor\\Saves";

    // A check to see if the directory does not exist.
    if (!Directory.Exists(path)) {
        // If it don't exist the create the directory at targeted path, set above.
        Directory.CreateDirectory(path);
    }
}

And lets say you used it and your computer name was "Johnny" or something it obviously wouldn't work.. And that's what I need help with.. Any info where I can read about this or can someone just explain how to do such?

open a command prompt and run set to quickly get a list of all environment variables you can use the userprofile variable instead of hardcoding C:\Users\Jay

Thank you, I will look into this. If I cannot get it working I'll report back with my issue and updated code.

a good idea is to also use Path.Combine or Path.Join (depends what the inputs can be) to make this cross-platform, you'd need to choose an environment variable name based on the current OS, https://en.wikipedia.org/wiki/Environment_variable#True_environment_variables

Environment variable

An environment variable is a dynamic-named value that can affect the way running processes will behave on a computer. Environment variables are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME ...
