Importing Books
Cadmus scans your device’s storage and adds books to its database automatically. This process is called importing.
Automatic import on startup
Cadmus automatically imports books every time it starts. The import is incremental: files whose modification time and file size haven’t changed since the last import are skipped, avoiding unnecessary re-fingerprinting. Only new or modified files are processed, significantly improving startup performance for large libraries.
Copy files to your device, restart the app, and they’ll appear in your library right away.
Force full import
If you suspect the import cache is stale or corrupted, you can force a full re-import:
- Open Settings.
- Navigate to the Import section.
- Tap Force Full Import.
- Confirm when prompted.
This bypasses the incremental import cache and re-fingerprints all files in your library directories. Be aware that this can take time and drain the battery for large libraries, so keep your device plugged in while it runs.
