These options can allow you to copy a file to a floppy disk, drop it on a printer or load it into a favourite application, all of which are listed under the SendTo menu.

MA194Using WindowsNT11 Adding to the SendTo menu Look in your account’s home directory and find the SendTo folder. Dragging icons of programs (shortcuts) into this area will automatically add them to the SendTo menu. By default, you should see entries for your briefcase, the floppy drive and perhaps a printer. Add a program, such as Netscape.
