Ok, I understand now. You are correct the typical file types used won’t be known extensions. Is there a reason for the redundancy of showing the extension in the file name and having it shown in the column directly to the right of it? When the file format is changed it automatically changes the extension in the file name cell, but if you change the extension in the file name it doesn’t choose the correct file format even if it is a valid file format. Reading left to right I change the file name first and then choose the file format second.
