NoteBook allows you to store multiple documents (pages) in one file. There is a full Rich Text Editor, which allows you to choose fonts and and text formatting options (e.g. bold, italic etc.). Types of pages that can be stored include Rich Text Format, plain text, HTML, pictures (.GIF, .JPEG, .PNG, and .BMP), images from your scanner/webcam via TWAIN, sound (MP3, MIDI, WAV, and WMA), and any other file, which can be launched from within NoteBook.
All of these are stored in one file, which can be password protected. If you have files of one particular topic that you want to keep together, this program is ideal. You could also use this program as a way of archiving e-mails or other documents.
