Hello! My colleague sent me his aticle but I can't open it. Could someone help me? I expect it to be a Word document because he always sends me documents created in Microsoft Word. And what is the file he sent me now… I can't get it. He said he sent me a document. From the extension (I see docx) I understand it should be a Word document. I renamed it to doc to open it in Word. I guess he renamed the file to avoid problems with the mail client, or spam filters or something. They created so many barriers for making communications the way we did it before... But I can't open it. Maybe I do something wrong? I can't contact him right now but I need this file today. Could somebody please help me?
