KDE is known to have a 1001 settings which can be changed to suit the users wishes. This can take a long time. When you re-install a distro, or perhaps jump to another, you've got to do it all again. I have a few questions about this: 1) Is it possible (sure it is) to place each and every KDE config file (for each and every program and part of Plasma, etc) in one directory, now they are everywhere. Making a backup would be so much easier to do. 2) Can you create a backup program to backup the settings, just as you did in Kontact where it is now very easy to create a backup of all your mail from within the program, instead of trying to find all the akonadi files which are scattered around. Kudos for that. For a modern DE, and I considder KDE to be THE DE this is almost mandatory to have. So if somebody can have a look at this, I and I'm sure many with me, will be very happy Setting up a new installation will then be peanuts compared to what it is now. Thank you very much.
Under ~/.local/share/ I see many folders for KDE apps like Dolphin, kate, kmail, etc. Would it not suffice to copy this folder as into your backups? But as for #2, I think that's a great idea to have a program that can backup the settings for common KDE apps. It would be a pretty huge undertaking so there would need to be some dedicated people working on this project. I'd be very happy to help but my knowledge of QT and C++ is limited.

In the future, please use one ticket for one issue. 1) All KDE applications should use the XDG standard ~/.config/ folder. If not, please report a ticket for the application in question separately. Note that ~/.config/ is different from ~/.local/share/ The former is used for configuration files, the latter is used for application data. Think "UI colors" and "address book entries" to understand the difference. 2) Marked as duplicate.
As I see it, and I am only a computer user no somebody who can dive deep into things, placing all files belonging to KDE app in 1 folder would make backing them up very easy: all you need to do is copy that 1 folder and you are sure you have everything. Doesn't have to be so complicated.
