Array of settings values are recommended to keep inside a .net core Appsettings file

I am building a console app and i have to save a couple of settings values and some of them is an array of values A sample section of Appsettings i am thinking is like below

    "FolderSettings":{
            "source": "c:\\sourcefolder",
            "target": "c:\\targetfolder"
    },
    "FolderJPG":[
        {
        "name":"foldername",
        "width":1450,
        "height":1450
        }
    ],
    "FolderPNG":[
        {
        "name":"foldername",
        "width":300,
        "height":300
        },
        {
        "name":"foldername2",
        "width":450,
        "height":450
        }
    ]

Is it recommended to save the array of settings values in appsettings file [ FolderJPG and FolderPNG in this case ] or is there any recommended ways to keep such settings in .net core?

Also, how can i fetch the settings values as an array of values? I know the way to read a simple key-value pair will be like

    _configuration.GetValue<string>("FolderSettings:source");

But how can I read the array of settings values for FolderJPG, FolderPNG etc correctly ?

Bind it to the model

public class FolderOption
{
   public string Name { get; set; }
   public int Width{ get; set; }
   public int Height{ get; set; }
}

Then

_configuration.GetSection("FolderJPG").Get<List<FolderOption>>();

The appsettings.json can contain any configuration that you need with restriction - it should be JSON.

JSON objects are written in key/value pairs.

Keys must be strings, and values must be a valid JSON data type (string, number, object, array, boolean or null).

So, an array is just data type of value
