To edit 12M file, we strongly recommend installing software that works with 12M files. Using tools such as 12M Online Editors gives less editing possibilities than software adapted to work with the 12M file format.
Please note that not every program that supports 12M will allow you to edit the file. If you want, you can learn more about the 12M file extension.
This is the best way. Try to open the 12M file with one of the programs and it will see if you can edit the 12M file. You will avoid the danger of virus installation if you download the software from the software developer 's website. Links to the websites of software producers can be found on the software subpages. List of sample programs supporting the 12M file below.

Some file formats are just plain text files that you can open with Notepad. But beware - making manual changes to the 12M file or another may result in its damage. If you make inappropriate changes and save the file, it may happen that you do not reopen the 12M file.. By far the safest way is to use file editing programs that works with the 12M extension.
It is actually certain that one of the applications working with files in the 12M format will be able to edit the file. Use other options if you still haven't found a way to edit 12M. Verified websites with the option to edit the file in the 12M format below.
