What is a FB2 file?

Fb2 file extension has FictionBook 2.0 file type, developed by FictionBook, which is associated with the "ebook files" category.

These are files in an eBook format, which was developed by Russian enthusiasts. This format was designed for fictional literature in the first place. A typical FB2 file includes XML that describes all elements of the book. You can use various eBook reading applications (Windows, Linux, and macOS) to open an FB2 file. The FB2 format is adapted for Unicode, metadata embedding, semantic markup, and inline formatting. Due to this amount of features FB2 files can be rather big, especially if they contain embedded images.

Zipped FB2 files can have two types of extensions: ".zip" or ".fb2.zip" extension.
