Downloading images and save to device - unity3d

Question

I having some issues here with UnityWebRequest.
I tried to download and save the jpeg, but it seem that the download is a success but it does not save it, and does not show me Log from "saveToFile" function.
Did I did something wrong?
Here are my code.
public string folderPath;
void Start()
{
folderPath = Application.persistentDataPath + "/" + FileFolderName;
}
IEnumerator DownloadingImage(Uri url2)
{
Debug.Log("Start Downloading Images");
using (UnityWebRequest uwr = UnityWebRequestTexture.GetTexture(url2))
{
// uwr2.downloadHandler = new DownloadHandlerBuffer();
yield return uwr.SendWebRequest();
if (uwr.isNetworkError || uwr.isHttpError)
{
Debug.Log(uwr.error);
}
else
{
Debug.Log("Success");
Texture myTexture = DownloadHandlerTexture.GetContent(uwr);
byte[] results = uwr.downloadHandler.data;
saveImage(folderPath, results);
}
}
}
void saveImage(string path, byte[] imageBytes)
{
//Create Directory if it does not exist
if (!Directory.Exists(Path.GetDirectoryName(path)))
{
Directory.CreateDirectory(Path.GetDirectoryName(path));
Debug.Log("Creating now");
}
else
{
Debug.Log(path + " does exist");
}
try
{
File.WriteAllBytes(path, imageBytes);
Debug.Log("Saved Data to: " + path.Replace("/", "\\"));
}
catch (Exception e)
{
Debug.LogWarning("Failed To Save Data to: " + path.Replace("/", "\\"));
Debug.LogWarning("Error: " + e.Message);
}
}

You have wrong file name so give filename with extension,
If you don't give extension, 'Directory.Exists' doesn't know whether file or directory.
or you could separate parameters such as rootDirPath and filename.
IEnumerator DownloadingImage(Uri url2)
{
Debug.Log("Start Downloading Images");
using (UnityWebRequest uwr = UnityWebRequestTexture.GetTexture(url2))
{
// uwr2.downloadHandler = new DownloadHandlerBuffer();
yield return uwr.SendWebRequest();
if (uwr.isNetworkError || uwr.isHttpError)
{
Debug.Log(uwr.error);
}
else
{
Debug.Log("Success");
Texture myTexture = DownloadHandlerTexture.GetContent(uwr);
byte[] results = uwr.downloadHandler.data;
string filename = gameObject.name+".dat";
// saveImage(folderPath, results); // Not a folder path
saveImage(folderPath+"/"+filename, results); // give filename
}
}
}
