Software supporting ONM files

If our ONM Viewer Online did not help you, you have a few more options. One of them is to use software that works with the ONM file. Here are some sample programs that can help you. By choosing the option to install dedicated software, you will also be able to e.g. edit the ONM file and sometimes even convert the ONM file.

Advantages and disadvantages of dedicated software

Note, however, that this solution requires you to download and install the software dedicated to handling the ONM file on your device. In this situation, unfortunately, you cannot see the ONM file online. This method is more complicated, but it offers more possibilities for working with the ONM file.

Other ways to view the ONM file

If you still cannot see the contents of the ONM file, but also don't see the need to install dedicated software, then there are other solutions. Many file types are simply text files or data archives. In this case, you can try to open your ONM file with the simplest text editor, for example with "Notepad". This solution does not guarantee that the problem will be solved, but it will often allow you to view the data in the ONM file to some extent.

The second way is to use a data archiving program. Check if you can open your file with eg Winrar. If the file is a data archive, you should see what individual files it consists of. Go to the information page about the ONM file extension. to see what kind of data it contains.
