OK, so the other day I was surfing around and came across this old chestnut at Download Squad: if you open Notepad and type .LOG at the very beginning of a new text document, then save the file, Notepad will automatically append the time and date to the file every time you open it. How is this useful? Well, I’m not entirely sure. Perhaps you’re a contractor and need to keep track of the time spent at a client’s site. Just open the file and type “Began work” underneath Notepad’s time stamp and you can use it as a log. Maybe you’ve got a noisy neighbor and you need to keep track of the racket they make. I dunno. The only thing you need to remember is that the .LOG bit is case-sensitive, so .Log or .log won’t work.
If you’d like to add the time and date to a Notepad file manually, just press the F5 key.
