Hello there. Newt\'s files aren\'t automatically saved in a particular location. Just as with Notepad, for example, you\'re prompted to where you want to save your file. If you\'ve never changed the default save path, you\'ve probably been saving to where Newt is installed. To find out where that is, simply choose File/Open and if you see your files at that point, you should also see a path and be able to get to that path in Windows Explorer.
If they were saved somewhere else on the drive, you could always do a search for anything ending in *.mrf, as this is the extension we currently use.
