Can anybody explain how to change file extension associations with applications to open them with in Fedora/KDE ? E.g. my PDFs open with Okular and I would like to change the default to Adobe.

There are a few things you can set under System Settings (Workspace Appearance and Behaviour) -> Default Applications, such as the terminal and browser app to use.

With regard to things opened from the KDE file manager, Dolphin, I believe those are contolled from System Settings (Common Appearance and Behaviour) -> File Associations. While I do use fedora+kde, I don't actually use dolphin, so I can't say for sure which is the right one WRT, eg, pdfs, but application->pdf looks promising (there's a search there too).

You will probably also be interested in this dolphin feature.

Actually, while I do have Dolphin installed, I prefer using Thunar. Do you know if it is possible to set it at a global and not just FS browser level so that it works regardless from which FS browser you open it from? – amphibient Mar 6 '13 at 21:56
@foampile By incorporating it into the "Systems Settings", KDE is maybe making the attempt, but doing that at the DE level is pointless: by that logic all file browsers would then have to implement umpteen DE methodologies. The "freedesktop.org" group who have to a significant degree instituted some pan-linux or posix standards of this sort would seem the most appropriate organization to try such a thing. I think the great majority of users use one file browser or another and won't consider setting this a big hassle anyway ;) – goldilocks Mar 7 '13 at 1:10
in fact, when i followed your instructions, Adobe is indeed on top and Okular is 2nd but Thunar still opens it with Okular – amphibient Mar 7 '13 at 1:18
@foampile Right, because nothing other than a KDE specific app is going to implement and check for a KDE specific configuration method. I suppose the KDE people could create something which automagicly hacked the configuration of whatever (popular) installed detected filebrowsers, but that would be quite the mess. So short of a common standard, there you are. – goldilocks Mar 7 '13 at 1:32
