Hi everybody! Well, I have a question. Actually, I guess that this question must have been asked (many times) before, but having searched on Google for almost an hour, I couldn't find anything helpful. :-( Now, the issue is this: Let's assume I have an HTML file (.html) on my system. I locate it in Nautilus and right-click on it in order to see its properties. In the properties dialog that pops up now, I see that the file is of "Type: HTML page" and of "MIME-type: text/html". Additionally, it has a nice icon suggesting that it is a HTML page. So far, so good. But now let's assume I have a file of a type GNOME does not know (imaginary estension: .foo). I can now, in the preferences, select that GNONE should open this type of file using a certain application. But what I couldn't figure out is how to let GNOME know the type of this file. In my Google search, I found several articles about setting up a MIME-type for unknown files. But actually, in the file properties as shown in Nautilus, there is not only a MIME-type being shown, but also something I'd like to call "file type description". This is listed in the properties as "Type:" (in contrast to "MIME-type:). In case of the HTML document, this was "HTML page". So, how do I assign such a "file type description" to a file GNOME doesn't know? In my example, I'd probably like my .foo file to be shown as being a "Foo Test File". Any ideas how to do that? Greetings, Nils
