Further, DOS for Dummies remains an entertaining book and if you use DOS, it's the book you want to assist you. The basic idea of this book is that you can identify a problem you're having with your computer, ranging from how to turn the thing on to how to back up only the files that have changed since the last backup.

Later chapters deal with troubleshooting.
The newest material in this release of DOS for Dummies deals with DOS 6.22 and the DOS-like shell that you can use under Windows 95 and Windows 98. For users of the latest versions of Windows, Gookin demonstrates some relevant procedures. DOS for Dummies is funny, too, in a wry sort of way. The author manages to infuse practically every passage with humor. Other computer books should make an effort to take themselves less seriously.
