C# EnumerateDirectories should not use localized paths

The code below produces following output:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs

C:\ProgramData\Microsoft\Windows\Start Menu\Programme (Localized German)

Problem: These are both referring to the same directory but I can not call EnumerateFiles on the localized path (which wouldn't make sense anyway) because it produces an System.UnauthorizedAccessException and this also means I can not use EnumerateFiles with SearchOption.AllDirectories because I get the same Excepetion.

Is there a way to only get the functional non-localized paths out of EnumerateDirectories?

//Root Directory is C:\ProgramData\Microsoft\Windows\Start Menu
foreach(DirectoryInfo directoryInfo in rootDirectory.EnumerateDirectories("*", SearchOption.TopDirectoryOnly))
{
    Console.WriteLine("Dir: " + directoryInfo.FullName);
    //C:\ProgramData\Microsoft\Windows\Start Menu\Programme
    //C:\ProgramData\Microsoft\Windows\Start Menu\Programs
    foreach (FileInfo fileInfo in directoryInfo.EnumerateFiles("*", SearchOption.TopDirectoryOnly))
    {
         //do stuff
    }
}

You have to recursively go through each directory so you can add an exception handler when you do not have access to a folder. Below is an example of the code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;

namespace SAveDirectoriesXml
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        const string FOLDER = @"c:\temp";
        static XmlWriter writer = null;
        static void Main(string[] args)
        {
            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;

            writer = XmlWriter.Create(FILENAME, settings);
            writer.WriteStartDocument(true);

            DirectoryInfo info = new DirectoryInfo(FOLDER);
            WriteTree(info);
            
            writer.WriteEndDocument();
            writer.Flush();
            writer.Close();
            Console.WriteLine("Enter Return");
            Console.ReadLine();

        }
        static long WriteTree(DirectoryInfo info)
        {
            long size = 0;
            writer.WriteStartElement("Folder");
            try
            {
                writer.WriteAttributeString("name", info.Name);
                writer.WriteAttributeString("numberSubFolders", info.GetDirectories().Count().ToString());
                writer.WriteAttributeString("numberFiles", info.GetFiles().Count().ToString());
                writer.WriteAttributeString("date", info.LastWriteTime.ToString());
             

                foreach (DirectoryInfo childInfo in info.GetDirectories())
                {
                    size += WriteTree(childInfo);
                }
                
            }
            catch (Exception ex)
            {
                string errorMsg = string.Format("Exception Folder : {0}, Error : {1}", info.FullName, ex.Message);
                Console.WriteLine(errorMsg);
                writer.WriteElementString("Error", errorMsg);
            }

            FileInfo[] fileInfo = null;
            try
            {
                fileInfo = info.GetFiles();
            }
            catch (Exception ex)
            {
                string errorMsg = string.Format("Exception FileInfo : {0}, Error : {1}", info.FullName, ex.Message);
                Console.WriteLine(errorMsg);
                writer.WriteElementString("Error",errorMsg);
            }

            if (fileInfo != null)
            {
                foreach (FileInfo finfo in fileInfo)
                {
                    try
                    {
                        writer.WriteStartElement("File");
                        writer.WriteAttributeString("name", finfo.Name);
                        writer.WriteAttributeString("size", finfo.Length.ToString());
                        writer.WriteAttributeString("date", info.LastWriteTime.ToString());
                        writer.WriteEndElement();
                        size += finfo.Length;
                    }
                    catch (Exception ex)
                    {
                        string errorMsg = string.Format("Exception File : {0}, Error : {1}", finfo.FullName, ex.Message);
                        Console.WriteLine(errorMsg);
                        writer.WriteElementString("Error", errorMsg);
                    }
                }
            }

            writer.WriteElementString("size", size.ToString());
            writer.WriteEndElement();
            return size;

        }
    }
}
