Opening DNL files

Did your computer fail to open a DNL file? We explain what DNL files are and recommend software that we know can open or convert your DNL files.

What is a DNL file?

Files with the .dnl file extension are most commonly associated with eBook files created by the DNAML desktop publishing application. The DNL files contain the navigation information, raw text and images of an eBook created with the software. The DNL file format uses DRM protection to prevent a user from accessing the eBook on unauthorized devices.

The .dnl file extension is also used for Concordance database files and netMod modem firmware upgrade files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
