.DNL File Extension
What is a DNL file?
eBook file created and used by DNAML desktop publishing software; contains raw text, image, and navigation data stored in a compact format for efficiency; protected using digital rights management (DRM); used by publishers and authors to distribute secure eBooks.
While DNL files are primarily used for eBooks, they may also be used for eCatalogs, ePresentations, eCards, eBrochures, and photo albums.
DNL files may be packaged as standalone executable (.EXE) files, which each include the DNL Reader.
NOTE: DNL Reader and DeskTop Author are discontinued.
