Initially developed in Russia for easy parsing and conversion across different eBook readers, it preserves metadata and structure effectively. FB2 is mainly used for fictional literature, allowing detailed descriptions of text formatting, titles, and subtitles, which enhances the user reading experience. Its open-standard nature ensures broad compatibility and ease of modification, making it a preferred choice in digital publishing.

A 2 file extension refers to a Unix manual page (man page) that documents a specific system call. These files are part of the Section 2 of the Unix manual, which is dedicated to system calls. Each 2 file is named after the system call it describes, such as "link.2" for the "link" system call. These files are intended to be viewed using the "man" utility in Unix-based systems. Historically, they have been a fundamental part of Unix documentation, providing detailed information on how to use system calls, their return values, possible errors, and related manual pages.
