Long Filenames and DOS Applications

DOS applications don't understand the longer filenames commonly used under Windows. So when saving your files, you'll need to restrict yourself to using only eight characters, plus a three-character extension, like this: CARSALES.WKS.

You don't have to worry about forgetting this requirement; the program won't let you use more characters in your filenames. But if you need to export a file from some other program and then use it in your DOS program, you'll need to remember the eight plus three restriction.
