What is a BCBK file?
A BCBK file is a data file created by Book Catalogue, a book organizing app developed by Evan Leybourn for Android. It stores a backup of a user's book collection, including information about the books they have entered, such as titles, authors, series, and other details. BCBK files make it possible for a user to restore the collection later if they reinstall the app or move to a new device.
More Information
The Book Catalogue app is an open-source tool that helps readers, collectors, or anyone who wants to track and maintain a personal book collection on their Android device organize their personal libraries. It allows people to add books by scanning barcodes, entering ISBNs, or filling in details manually. To protect their data, the app gives users the option to back up their catalog in different formats. While .CSV exports are designed for sharing or editing in spreadsheets, BCBK files serve as the app's dedicated backup format, intended for restoring collections directly inside Book Catalogue.
Common BCBK Filenames
BookCatalogue-YYYY-MM-DD.bcbk - File naming convention for BCBK files. For example, a file exported on June 24, 2025 is named BookCatalogue-2025-06-24.bcbk.
How to open a BCBK file
You can open BCBK files with Book Catalogue on an Android device. You can open a BCBK file by selecting Import from Archive in the Book Catalogue app.
