NTM file format details:

If you know the file format, you can also find out how to open or edit the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the NTM files is as follows:
