Your teacher needs a teacher.
notepad word wrap can be turned OFF before you open any document.
Open notepad
format, uncheck wordwrap.
then use file OPEN to open your file.
Notepad will not insert extra characters if you turn off the wrapping.
You can also add to your SEND TO function when you right click...
Ex, if you contantly place a copy of your documents on another drive (on a network, we are constantly sending to our temporary folder on the server for transfer to other computers) you can have that location put on the list of send to (like A: , etc)
If you want to learn how to do that, let me know.
