Getting Error message when I try to import "" file created in another server

I am getting below error message, when I try to import file "" into my local server.

Note: I stored the file in my documents and just gave the location in path.

My purpose here is, some of the methods and item types created in another server, I would like to export and import into my local server. So one of my colleagues sent me this "imports.imf" file which I am trying now to import using Import utility but getting below error message.

Please help and provide solution.
