OpenFilePickerAsync() - FilePickerOpenOptions.SuggestedStartLocation not working when folder path contains spaces (macOS)

[werkflo]

When I call OpenFilePickerAsync() with FilePickerOpenOptions where SuggestedStartLocation has been fed an IStorageFolder provided by TryGetFolderFromPathAsync(), everything works fine as long as the folder path contains no spaces. However, when the folder path contains spaces, the file picker falls back to default behavior of opening in the last location a file picker was open to.

If it matters, I'm running this on macOS.

Reproduction

Make 2 folders on your Desktop:

• one called "TargetFolder"
• the other named "Target Folder" (as in "Target[SPACE]Folder")

And then run the following code:

    private async void Button_OnClick_WithoutSpaces(object? sender, RoutedEventArgs e)
    {
      await TryToOpenFolderOnDesktopWithName("TargetFolder");
    }


    private async void Button_OnClick_WithSpaces(object? sender, RoutedEventArgs e)
    {
        await TryToOpenFolderOnDesktopWithName("Target Folder");
    }
   
    
    private async Task TryToOpenFolderOnDesktopWithName(string folderName)
    {
        var basePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        var targetPathWithSpaces = Path.Combine(basePath, folderName);
        Console.WriteLine($"Trying '{targetPathWithSpaces}'");
        var result = await DoOpenFilePickerAsync(targetPathWithSpaces);
    }
    
    private async Task<List<IStorageFile>?> DoOpenFilePickerAsync(String? providedPath)
    {
        if (Application.Current?.ApplicationLifetime is not IClassicDesktopStyleApplicationLifetime desktop ||
            desktop.MainWindow?.StorageProvider is not { } provider)
            throw new NullReferenceException("Missing StorageProvider instance.");
        
        // Setup the starting folder
        IStorageFolder? startingLocation = null;
        if (providedPath != null)
        {
            startingLocation = await provider.TryGetFolderFromPathAsync(providedPath);
        }

        if (startingLocation != null)
        {
            Console.WriteLine($"-- Good starting location found - {startingLocation?.Path.AbsolutePath}");
        }
        else
        {
            Console.WriteLine($"-- startingLocation is null");

        }
        
        // TODO: BUG? if the path for startingFolder contains spaces, it will default to wherever it last opened.
        var files = await provider.OpenFilePickerAsync(new FilePickerOpenOptions()
        {
            SuggestedStartLocation = startingLocation,
        });

        return files.ToList();//?.Count >= 1 ? files[0] : null;
    }

The Console output (for me) is:

Trying '/Users/jramsey/Desktop/TargetFolder'
-- Good starting location found - /Users/jramsey/Desktop/TargetFolder/
Trying '/Users/jramsey/Desktop/Target Folder'
-- Good starting location found - /Users/jramsey/Desktop/Target%20Folder/

When the Button_OnClick_WithoutSpaces() button is clicked, a file picker appears that starts out pointing to the "TargetFolder" folder on the Desktop. However, when the Button_OnClick_WithoutSpaces() button is clicked, a file picker appears that is still pointed at the "TargetFolder" button, as that was the last folder that a file picker was pointed to.

I can click the WithoutSpaces button and navigate somewhere else. When I click the WithSpaces button, I go to the last location the other button was viewing.

I've got to be doing something wrong... Anybody?

It was fixed in latest builds #17594

Outstanding! Thanks for the quick response.
