I cannot open CoCreate PE/ME30 File

Hello , 

I have a file wihout extension, but according to my researches it is ME10 file with (.mi) extension. Firstly I tried to open it by changing name and extension. As a result I wrote (.mi) and opened it on "Creo Elements/Direct Modelling Express 8.0". So it is succesfull method to open 2d ME10 file.

Also I have an another file that it is without extension too. But this file is not working with (.mi) extension on "Creo Elements/Direct Modelling Express 8.0". The reason of this problem that probably this file was created by ME30. It is 3d model. I tried a lot of extension to open it on the program but failed. 

I cannot drop this file here because of company's policies.

Years ago, files as these files without extension created on HP-UX OS. By years by as technology changes, ME30 became Creo Elements/Direct Modelling. I made a deep research in internet and found this kind of knowledges.

Can anybody help me to open this "ME30 file" ? Thanks for reading my text. Regards...
