What is an FB2 file

FB2 files mostly belong to FBReader by FBReader. An FB2 file is an e-book saved in FictionBook format. It is actually a ZIP-compressed archive containing a single XML document which describes individual elements of an e-book using tags. Markup saved in this XML file specifies the structure (paragraphs, verses, quotes, footnotes, tables, subtitles, and epigraphs), not the appearance of a book. Unlike most e-book formats, FB2 saves images as Base64-encoded data within the XML file. It does not support any kind of digital rights management. E-book readers such as FBReader, Calibre, and CoolReader support FB2 format. FictionBook e-books can also be stored as FB2.ZIP or FBZ files.

How can I open an FB2 file?

You need a suitable software like FBReader to open an FB2 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FB2 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FB2 file directly in the browser:. Just drag the file onto this browser window and drop it.

FB2 file format:

The file format determines how the data is stored in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program.

As a file extension, FB2 isn't very common and mainly uses a special format. But the following two file formats are common:

• 85% of all FB2 files are FictionBook 2 files, which are based on the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. A typical file size is 910 KB. The file type is old but is used even today. Certain words are almost always found in the files, such as genre, <?xml version="1.0" encoding="UTF-8"?>, <description>, <title-info> and <FictionBook xmlns="http://www.gribuser.ru/xml/fictionbook/2.0" xmlns:l="http://www.w3.org/1999/xlink">. These files are attributed to epdf, handmaids, deltora, engines, litmir, mortal and tale, and often consist of personal data.
• 10% of all FB2 files are based on the zip format, so several files are compressed and saved in one FB2 file. Primarily one file is included. If you'd like to see the images and files included, just rename the file extension to .zip and double-click. Most of these files are 120 KB to 600 KB in size. Such FB2 files store data about person-related data.

All other FB2 files (5%) have no uniform format, frequently e.g. XML. Often described as handbook, pdfdrive or woman. If you want to find out which format your FB2 file belongs to, just click on the button "Choose your .fb2 file to view".
