What is NMF file?

The NMF file has been categorized as GIS Files. It was designed by ESRI. GIS Files consists of 255 similar files. ArcGIS Explorer Map Format is supported by 2 operating systems. These systems consist of Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use Mozilla Firefox to handle this file. This is a program created by Mozilla. Alternatively, you can use 3 other programs. ArcGIS Desktop, ArcGIS Explorer will apply when it is not possible to use Mozilla Firefox.

How to open NMF file?

The main problem with ArcGIS Explorer Map Format is that the NMF file is incorrectly associated with programs. Thus, when you open NMF, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the NMF 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 Mozilla Firefox

The first step is to check if the computer has the Mozilla Firefox program installed. This can be achieved by typing Mozilla Firefox into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file NMF with Mozilla Firefox. Later in this article you will find a list of programs that can open NMF files.

Step 2. Create association of Mozilla Firefox with NMF files

If, despite the installed application, the NMF file does not start in the Mozilla Firefox 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. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the NMF file with the Mozilla Firefox application.

Step 3. Update Mozilla Firefox to the latest version

If, despite the association of the Mozilla Firefox program with the ArcGIS Explorer Map Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Mozilla website or update the program from the application.

Step 4. Check for the following problems with the NMF file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the NMF file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our NMF file. However, remember that not every infected NMF file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the NMF files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular NMF file corruption. The easiest way is to restore the file from a backup, if there is one, or contact ESRI
The program indicates that the file is encrypted or corrupted. The encrypted file NMF 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the NMF file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
