Rescan library

What is checked

• Each book’s files — on the device and in iCloud Drive. A book offloaded to iCloud does not count as missing.
• A book with not a single file found, either on the device or in iCloud, gets the “Files not found” mark on its card. If the files come back, the mark is removed. If only some of the files are missing, there is no such mark, but the book is counted in the check’s result.
• The length is worked out for files that lack it.
• Text books — epub, fb2, pdf — get a cover search if they have none. Rescanning does not look for covers for audiobooks.
• The search in the app and the phone’s search are rebuilt.
• Genres from tags that are spelled the same as the app’s genres are merged with them. Books do not lose their genre.

What does not change

• Books, files, progress and bookmarks: nothing is deleted.
• No new books appear: new files are picked up by import.
• Books in the trash are not checked.

Result

Before it starts, the app asks “Rescan the library?”. The result appears as a line under the “Maintenance” section: how many books were checked, how many have at least one file missing, how many lengths were fixed and, if any turned up, how many covers were found. On a large library the check takes up to a minute.

Tip

If a single book won’t play and its card shows “Files not found”, start with it: “Check again” checks only that book. Rescanning is for when a lot has drifted apart — for example, after moving files or restoring the catalog from a backup.
