I just followed this tutorial to delete a folder and its content

    public ActionResult Product_Delete()
    {
        string idnumber = "07";

        string path1 = @"~/Content/Essential_Folder/attachments_AR/" + idnumber;

        DirectoryInfo attachments_AR = new DirectoryInfo(Server.MapPath(path1));
        EmptyFolder(attachments_AR);
        Directory.Delete(path1);

        ....
    } 

    private void EmptyFolder(DirectoryInfo directory)
    {

        foreach (FileInfo file in directory.GetFiles())
        {
            file.Delete();
        }

        foreach (DirectoryInfo subdirectory in directory.GetDirectories())
        {
            EmptyFolder(subdirectory);
            subdirectory.Delete();
        }

     }

But using this its deleting all the contnet in 07 folder, but its not deleting the 07 folder finally.

I'm getting error in this line Directory.Delete(path1);

Once I debug I can see run time error with below message

Could not find a part of the path 'C:\Program Files (x86)\IIS Express\~\Content\Essential_Folder\attachments_AR\07'.

but path1 value is ~/Content/Essential_Folder/attachments_AR/07

The reason is that Directory.Delete cannot recognize ~ in the path.

You need to convert it to an absolute path using Server.MapPath() like you did it here:

DirectoryInfo attachments_AR = new DirectoryInfo(Server.MapPath(path1));

You may also want to convert it once, and use in both methods:

public ActionResult Product_Delete()
{
    string idnumber = "07";

    string mappedPath1 = Server.MapPath(@"~/Content/Essential_Folder/attachments_AR/" + idnumber);

    DirectoryInfo attachments_AR = new DirectoryInfo(mappedPath1));
    EmptyFolder(attachments_AR);
    Directory.Delete(mappedPath1);

    ....
}

By the way, there is absolutely no need to remove files manually. You can use

public ActionResult Product_Delete()
{
    string idnumber = "07";
    string mappedPath = Server.MapPath(@"~/Content/Essential_Folder/attachments_AR/" + idnumber);

    Directory.Delete(mappedPath, true);
}

which will remove all folders, subfolders and files recursively, and then will remove directory itself.
