We should all know how to save a text file like so:
richTextBox1.SaveFile(@"C:\hello.txt", RichTextBoxStreamType.PlainText);
But I want to save it to an external drive. So I would try:
richTextBox1.SaveFile(@"F:\hello.txt", RichTextBoxStreamType.PlainText);
BUT, F: can change to G: or E:, etc... F: usually has a name such as 'SD Card', though.
So how do I save to the Removable Disk 'SD Card' based on it's name?
