In most applications, you can choose "File" from the toolbar along the top of the screen. Click "Save As" in the menu that appears and a new window will open. Then you would specify the 3-1/2" Floppy (A:) by using the drop down menu labeled "Save In"/ Next you will need to name the file in the "File Name" space. Click the "Save" button when you are finished. The file is now saved to your floppy disk.
