        {
            try
            {
                var downloadDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Downloads);
                var xmlFiles = Directory.GetFiles(downloadDirectory, "P-COS_ScannerSettings_PCMBU4PQDL1_V1.xml");
                var xmlFileNames = xmlFiles.Select(f => Path.GetFileName(f));
                MyListView.ItemsSource = xmlFileNames;
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
        }

        private void MyListView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
        {
            if (e.SelectedItem != null)
            {
                var selectedXmlFileName = e.SelectedItem.ToString();
                var downloadDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
                var xmlFilePath = Path.Combine(downloadDirectory, selectedXmlFileName);
                var xmlContent = File.ReadAllText(xmlFilePath);
                var xmlDocument = XDocument.Parse(xmlContent);
                // Faites quelque chose avec le document XML .
            }
        }
    }

Could you share namespace about Environment.SpecialFolder.Downloads?

Which platform is not working when running code? If it not works in android, can you share your tested android device?

	public partial class DetailPage : ContentPage

			InitializeComponent();
            LoadXmlFiles();
        }
        private void LoadXmlFiles()
        {
            try
            {
                var downloadDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Downloads);
                var xmlFiles = Directory.GetFiles(downloadDirectory, "P-COS_ScannerSettings_PCMBU4PQDL1_V1.xml");
                var xmlFileNames = xmlFiles.Select(f => Path.GetFileName(f));
                MyListView.ItemsSource = xmlFileNames;
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
        }

        private void MyListView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
        {
            if (e.SelectedItem != null)
            {
                var selectedXmlFileName = e.SelectedItem.ToString();
                var downloadDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
                var xmlFilePath = Path.Combine(downloadDirectory, selectedXmlFileName);
                var xmlContent = File.ReadAllText(xmlFilePath);
                var xmlDocument = XDocument.Parse(xmlContent);
                // Faites quelque chose avec le document XML .
            }

Do you use System.Environment.SpecialFolder Enum, but this Enum do not have Downloads value, please share the namespace completely.

it's an android platform

Which target-framework did you set? If you set the target-framework to android 11 later, you can not access the download folder.

From android native document Manage device storage.

Starting in Android 11, apps that use the scoped storage model can access only their own app-specific cache files

Ineed to install Microsoft.Maui.Essential package but it won't install

Do you want to use these Essentials functions? If so, you install CommunityToolkit.Maui nugget package like thisCommunityToolkitMaui Get started document.
