Extracting *.my file type on N2000 MiB file series.

I use Zabbix for SNMP monitoring and I'm trying to create a Template for N2142 switch monitoring. I found N2000 MiB inside of a firmware file:

    But when I tried to extract all of MiB files, I realised that they are *.my extension (I've never seen this before). So, when I try to extract this file, windows return an unexpected error called: "Error 0x80004005: Unspecified error".

    Does anyone know this *.my file extension for MIB? Is there any especific Zip program to extract this kind of file?

I've read all possivel README file to find out an answer.

Thank you.
