how to import .mi file (cocreate ME10)?

hello,

I found in creo parametric the config.pro option

intf2d_in_mi_mapping_file

viewing this option, I should meen that is possible to import a .mi file??

1) in creo P. file/open menu, .mi is not present.

2) how to create the mapping file managed by this option?

3) is there an hidden option to be able to open cocreate me10 native files?

thanks,

Ron
