Storage & Cleanup
See how much disk space your library uses and free up space.
1. Storage Overview
Settings -> Storage & Data shows how much space each kind of file uses: raw scans, cleaned pages, translated pages, OCR previews, book covers, page thumbnails, the database and the translation cache. Click Refresh to measure again.
Your files are in the data folder described in Your Data & Updates.
2. Freeing Space
- Clear Thumbnail Caches: deletes thumbnails, cover previews and the translation cache. They are rebuilt when needed.
- Purge Orphaned Files: finds and deletes files that no page or book refers to any more, for example after an interrupted upload.
- Clear All Data: deletes your whole library and settings. This cannot be undone.
For a single book, open the book menu -> Storage & Files to see its size and clear its thumbnails.
Deleting a book, chapter or page also deletes its image files from disk.
