How to open DNF file?
The most common problem when using Duke Nukem Forever Map Format is that a specific DNF is not associated with the program. This is manifested by the fact that DNF files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the DNF file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Duke Nukem Forever

Programs to open DNF file
Remember to download programs supporting DNF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Duke Nukem Forever with DNF files
If, despite the installed application, the DNF file does not start in the Duke Nukem Forever application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the DNF file with the Duke Nukem Forever program.
Step 3. Update Duke Nukem Forever to the latest version
The fault may also lie with the Duke Nukem Forever program, it is possible that Duke Nukem Forever Map Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the 3D Realms/Apogee Software Ltd. page and install.
Step 4. Check for the following problems with the DNF file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the DNF file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our DNF file. However, remember that not every infected DNF file can be recovered, so it is important to take care of regular backups.
Older version of DNF file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged DNF files. The easiest way is to restore the file from a backup, if there is one, or contact 3D Realms
The program can also signal the fact of encryption. The encrypted file DNF except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the DNF file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the DNF file while scanning. If the problem persists, restart the machine.
