High Quality Content by WIKIPEDIA articles! Windows Journal is a notetaking application, created by Microsoft and included in Windows XP Tablet PC Edition as well as Home Premium or superior editions of Windows Vista and Windows 7. It allows the user to create and organize handwritten notes and drawings and to save them in a JNT-File. It is also able to simply use an ordinary computer mouse to compose a handwritten note, as well as a graphics tablet or a Tablet PC. Since the documentation for the JNT format is not available you have to rely on Microsoft providing a software to read the files.
