I would like to know whether it is possible to change the content of file types listed in that column. For some the amount of wording is too much eg for a Microsoft Word document:
Or is this controlled by the operating system?
Help with this would be gratefully received
You should be able to edit it via Settings -> File Types.
The names are stored in the registry, so some software/updates may change them back, of course.
The extension column is sometimes a better alternative to the type one, if you want something shorter.
Thank you very much for the information.
