NIS Elements, MetaMorph and a host of other programs rely on XML files to save settings that are user-adjusted inside the program. XML files are like mini databases that can be easily set up, modified and read by a host of programs. The tough part comes when you may need to manually edit one of these files. Viewing an XL file is difficult in IE, and editing it is even more difficult using wordpad or notepad! So Microsoft came up with a handy editor, which can be downloaded here – XML Notepad. I highly recommend keeping this tool handy!
