Get file association updated to include MMB extension?

[Confused]

This is the only program that I have ever encountered that I could not open in Windows by just clicking on a file extension in this case MMB. Why is this so & ask if it's possible to get this 'file association' file list updated to get it to work like all other programs?

I cannot quite understand the excitement.
The parameter file has the extension .db3, if it does, this file would have to be linked to MMEX. But this would not work with the portable version.
The extension .mmb is a database and cannot be used to start MMEX.

That working for me.

By default after installing MMEX neither .db3 nor .mmb is linked to MMEX.exe.
But this can be adjusted manually via "Properties/open with/select app".
If the linking of the files .db3 / .mmb with MMEX is useful and can not lead to problems is difficult to judge, because this extension is also used by other programs.
