notepad myfile.txtYou would now have a normal text file. But if you want to hide some text within that text file, you can actually create a (hidden) file, within the visible file. How? you ask .. well, comin' right up. Simple open up a command prompt, by going to start / run... and type cmd. Then type the following:
notepad visiblefile.txt:hiddenfile.txtThis will open up the file that is hidden within visiblefile.txt. hiddenfile.txt will not show up if you browse to the directory, or look at it in explorer, it's embedded within the visible file. So now if you want to edit visiblefile.txt, you simple double click on it within explorer, and if you want to edit the hidden file you created, you just type the same command line above to open it. Note, that if you delete the visiblefile.txt file, your hiddenfile.txt will also be deleted with it.
