I don’t understand why… I cannot symlink registrymodifications.xcu from a folder to /home/.config/etc etc.
So I have created two bash scripts to copy from and to that folder (when writer start and when close).
But it’s not the better solution.
SO: Kubuntu 18.04
@ajlittoz thank you for your answer, but I try to symlink from a my folder to my home folder, and I cannot symlink: I symlink correctly with Dolphin, but when I open LO the file in other folder is copied in home folder.
