I have a bunch of .RDP files I have saved for the Remote Desktop Client that was recently released. They are standard XML files with an RDP extension. I opened one up in TextEdit and modified some of the settings in the XML file. I did not change the extension. Now, though, when I double click the file, instead of launching Remote Desktop Client, it launches the file in TextEdit again! How do I make it open with Remote Desktop or have TextEdit not modify it's file type when I save it?
