Personal Diary with Notepad

This is a simple and yet useful (hidden) feature in Notepad that I learned recently. 

1. Create a new text file, with any name. 
2. Type ".LOG" (all uppercase ) at the first line.
3. Save (and close) as regular text file.
4. Every time we double-click to open the file, it will show the date/time, and we can just write any text below it. (good for keeping as forensic logbook)
