Where Does Xournal++ Store Settings?
Xournal++ settings file on Linux and Windows with toolbar layout and plugin state.
Last updated
Xournal++ keeps preferences, toolbar layout and plugin settings in a settings.xml file under its per-platform config folder. Notebooks themselves are .xopp files saved wherever you put them.
Deleting settings.xml resets the UI without touching a single note. Back up the config folder and your pens, shortcuts and plugins survive a reinstall.
Where Xournal++ stores this, by platform
~/.config/xournalpp/settings.xml
Main preferences file with toolbar and plugin state nearby. Notebooks live wherever you save them, independent of this config. Copy the xournalpp folder with the app closed.
%APPDATA%\xournalpp\settings.xml
Same settings role as Linux. Confirm the folder name on your install before scripting backups, since packaging can vary.
