You can import notes that were exported from RemNote (as backups stored in a .rem file, or as a knowledge base stored in a .db file), or from many other note-taking and flashcard apps, by clicking on your username in the upper-left corner of RemNote and choosing Import.
Clicking on an import type will show instructions on importing from that app.
Importing duplicate content
If you import content that is already in your knowledge base, RemNote applies some rules on a per-Rem basis to decide what to import:
If the document being imported has a Rem that doesn’t exist in your knowledge base at the location it’s found in the document being imported, the new Rem is added to your knowledge base. (Notice that if you have an identical Rem in a different document, this is a different Rem to RemNote, so you will end up with a copy in both locations.)
If the document being imported has a Rem that exists in your knowledge base and is exactly the same (in the same place, with the same content), the incoming Rem is skipped and your knowledge base remains unchanged.
If the document being imported has a Rem that exists in your knowledge base but has been changed, RemNote isn’t sure which version you want, so it imports the new Rem and keeps the old one right next to it. You can manually delete the version you do not want.
