Cool notepad trick

Text becomes unreadable
Open Notepad and then On the
very first line, type in
dont eat the donut
(without quotes) then save and
close the file.
Note: the file should have
only one line of the text
above.
Now, open the same file. You'll
notice the text becomes
unreadable squares. (try this
with different text with the
same format and length).
Create a log
Open Notepad On the very first
line, type in
.LOG
(without quotes) then press
Enter for a new line. Now you
can type in some text if you
want, then save the file.
Next time when you open the
file, notice its contents.
Notepad automatically adds a
time/date log everytime you
open the file Cool huh?
