|The editor can produce 2 basic types of books. Each book produced can be a stand-alone EXE application or a DNL data file.
Package EXE - Creates EXE books. Each stand-alone book is a single plain executable file which does not require any other programs to view it. However these files are vulnerable to infection by viruses. It is for this reason that they may be blocked from e-mail delivery by firewalls. If you experience problems distributing your .EXE file via e-mail try zipping up the file or alternatively use the .DNL format.
The best way to avoid email virus warnings is to upload the file to a web site where the end user can download it.
Package DNL - Creates a DNL file. A DNL file is a data only file (therefore resistant to computer viruses) but requires the end user to have a DNL reader to view it. It is also a slightly smaller download than an EXE file because it does not have the reader built in. Anybody can download the reader for free at: http://www.digitalwebbooks.com/reader/
Package DRM: Creates a DNL file with digital rights management protection (DRM). It has the same file properties as a DNL file with security added. For further information on how DRM works please refer to the ‘Employing DRM in Digital Web Books’ Chapter.
Package EXE DNL DRM: This creates a DNL DigitalWebBook with Digital Rights Management (DRM) Protection with DNL reader installer.
Package SCR: This creates a SCR Windows screensaver file so you can use your books as screensavers.
