The questions people ask when setting up Foldbook. Something else? Write to hello@believemy.com with your device, iOS or Android version and source (NAS, WebDAV, iCloud, OPDS). We reply within two business days.
Which sources can I add?
A NAS folder over SMB (Synology, QNAP, or a Mac or PC sharing a folder), a WebDAV server (Nextcloud, Synology), a folder from iCloud Drive or the Files app, an OPDS catalog (Komga, Kavita, Calibre-Web) and the files on your device. Tap “+” in the library to add one.
Which formats can it read?
CBZ, CBR (RAR4 and RAR5), CB7, PDF and EPUB.
My NAS doesn't show up or refuses to connect.
Check that your device and NAS are on the same network and that SMB sharing is on. On iPhone and iPad, Foldbook also needs access to the local network (Settings › Privacy & Security › Local Network). Away from home, use WebDAV, a VPN, or Foldbook Server.
Do I need an account?
No. Without one, your progress goes into a small file, .folio-progression.json, at the root of the share of your first NAS library, and every device reading that share finds it there. The optional account keeps your setup, progress and notes for all your devices.
How do I delete my account?
In Foldbook, Settings › Account › Delete my account. Everything the account keeps is erased right away.
My manga reads the wrong way.
Foldbook guesses the reading direction from the file. If it gets it wrong, tap the direction button in the reader: your choice is kept for the whole series.
What is panel-by-panel reading?
On an iPad in landscape, the “Panels” button shows the panel large on one side and the whole page on the other, with the current panel outlined. Tap the edge to move to the next one.
How do I share my library?
Install Foldbook Server on your NAS, link it to your account, then invite people from Settings › Shared library. The install guide is on the Foldbook Server page.
A book is locked. How do I open it?
The lock asks for Face ID, Touch ID or your device passcode. To remove it, open the book or series menu and tap “Unlock”.
