5.打开示例文件夹（Application.OpenURL("file://" + Application.dataPath);）

 如果打不开文件夹，可能原因是有中文路径。改为英文路径就好了

#if UNITY_EDITOR
using UnityEditor;
#endif
using UnityEngine;

namespace QFramework
{
    public class OpenFolder : MonoBehaviour
    {
#if UNITY_EDITOR
        [MenuItem("QFramework/5.打开文件夹")]
#endif
        private static void MenuClicked()
        {
            Application.OpenURL("file://" + Application.dataPath);
        }

    }

}
