In daily life Notepad is a very small app comes along with each Windows Version.
This is real cool tip for people who use notepad to write down any info on a day to day basis...
In Notepad

* Create a blank text file with .LOG (CASE SENSITIVE) as the first line of the file, followed by a carriage return. [ Enter ]

* Save and close the file .

* Double-click the file to open it and notice that Notepad appends the current date and time to the end of the file and places the cursor on the next line.

* Type your notes and then save and close the file.


Each time you open the file, Notepad repeats the process, appending the time and date to the end of the file and placing the cursor below it
It simply serves as a virtual diary !
