saving a screenshot to the recources folder

Hello, I am trying to take a screen cap. of my game and save it in a folder which I can later Access. How do I save a screen Capture with

ScreenCapture.CaptureScreenshot("Screenshot.png");

and save it to the Resources folder or even the Application.persistentDataPath.
I know this is a verry stupid and easy quastion but I can’t seem to find a simple answer.
Thanks for your help in advanced .

Well you should not be ashamed for asking for help. Here is a simple example script. Hope it helps and cheers mate.

using UnityEngine;
//System.IO;: You need this to find the files in your Directory
using System.IO;

public class Your Script Name Here: MonoBehaviour {
    //screenCaptureKey: Change this to any key you want. It is easily changeable in the editor
    public KeyCode screenCaptureKey = KeyCode.F2;

    //ScreenCapDirectory: If you want a 
    //specific directory do something like this: "C:\\Users\\YourUserNameGoesHere\\Documents\\"
    //Or if you want to use Application.persistentDataPath put it in the 
    //void Start() method and leave this string empty.
    public string ScreenCapDirectory = "C:\\Users\\YourUserNameGoesHere\\Documents\\";

    //The name of the screen capture taken. Put anything you want
    public string ScreenCapName = "CoolPic";

    //This will be what type of file your screen capture is. Another type besides png is jpg.
    public string fileType = ".png";

    //Private variables to get how many screenshots exist
    private int count;
    private int ScreenCaps;

    void Start()
    {
        //Set them both to 0 at start
        count = 0;
        ScreenCaps = 0;

        //This file path is C:\Users\YourUserNameHere\AppData\LocalLow\YourEnteredCompanyNameHere
        ScreenCapDirectory = Application.persistentDataPath;
    }

    void Update () {
        //ScreenCaps: Say we have 2 files with the same name as your ScreenCapName,
        //            Well then this would just tell us 2 of those files exist.
        //            Then we add that value to our ScreenCaps number to reference later.
        ScreenCaps = (FindScreenCaptures(ScreenCapDirectory, ScreenCapName));

        //If we press our capture key
        if (Input.GetKeyDown(screenCaptureKey))
        {
            //This is how you save the screenshot to a certain directory and a certain name
            //(ScreenCaps + 1): We reference this from above and use it for our picture name
            //                  So if we know 2 files exist we add 1 to our value so it is a new picture.
            ScreenCapture.CaptureScreenshot(ScreenCapDirectory + ScreenCapName + (ScreenCaps + 1) + fileType);
            Debug.Log("ScreenCapture Taken!");
            Debug.Log("ScreenCap Location: " + ScreenCapDirectory);
        }
	}

    //This gets all the existing files from the Directory (DirectoryPath)
    //with the FileName(FileName).
    int FindScreenCaptures(string DirectoryPath, string FileName)
    {
        //Set count to 0 at every run so we count up from 0 to 
        //how many files exist with the FileName entered
        count = 0;

        //This loops through the files in your entered Directory
        for (int i = 0; i < Directory.GetFiles(DirectoryPath).Length; i++)
        {
            //If any file has the same name as your picture
            if (Directory.GetFiles(DirectoryPath)*.Contains(FileName))*

{
//Add 1 to the count because we need to know how many
//files with the same name exist
count += 1;
}
}
//Once we know we return that amount
return count;
}
}
