What is an FB2 file?
An FB2 file is a FictionBook 2.0 file saved in an eBook format developed in Russia. It contains XML that describes each element of the book and is designed primarily for fictional literature. FB2 files can be viewed by various eBook readers for Windows, Unix, and Pocket PC.
The FB2 file format specifies the structure of the eBook instead of the appearance. This makes it useful for converting into other formats. The format features simple semantic markup, metadata embedding, unicode, and inline formatting.
