Your Trilium data is stored in a SQLite database which contains all notes, tree structure, metadata, and most of the configuration. The database file is named document.db and is stored in the application’s default data directory.
When you run Trilium for the first time, it will generate a new database containing demo notes. These notes showcase its many features, such as:
There are some cases in which you may want to restore the original demo notes. For example, if you experimented with some of the more advanced features and want to see the original reference, or if you simply want to explore the latest version of the demo notes, which might showcase new features.
You can easily restore the demo notes by using Trilium’s built-in import feature by importing them:
Trilium provides a lot of flexibility, and with it, opportunities for advanced users to tweak it. If you need to explore or modify the database directly, you can use a tool such as SQLite Browser to work directly on the database file.
If you are doing any advanced development or troubleshooting where you manually modify the database, you might want to consider creating backups of your document.db file.
If you are experimenting with Trilium and want to return it to its original state, you can do that by deleting the current database. When you restart the application, it will generate a new database containing the original demo notes.
To delete the database, simply go to the data directory and delete the document.db file (and any other files starting with document.db).
If you do not need to preserve any configurations that might be stored in the config.ini file, you can just delete all of the data directory’s contents to fully restore the application to its original state.
