How to deal with hidden file extensions

Here's a piece of code:

if (fbFolderBrowser.ShowDialog() == DialogResult.OK)
{
   originalFiles = Directory.GetFiles(fbFolderBrowser.SelectedPath);
   supportedFiles = originalFiles.Where(s => s.EndsWith(".jpg") || s.EndsWith(".bmp") || s.EndsWith(".tiff") || s.EndsWith(".jpeg") || s.EndsWith(".gif")).ToArray();
}

What if in the directory selected, the files' extensions are hidden? Does it mean I won't be able to use "EndsWith?"

What would be the correct way to KNOW the file extensions?

You will still see the extension if you access the directory from code. The "hidden" extension only hides it when browsing to files through the UI.

Hiding file extensions is a behavior of the UI run by the Windows shell.

It has no effect on your code; all actual filepaths will still have extensions.

Bonus: Look at the Path.GetExtension() method.
