Convert TAR Files to EPUB in Java

What is TAR file format?

A TAR (tape archive) file serves as a versatile archive format, primarily utilized on Unix and Linux systems, housing multiple files alongside their associated metadata. This metadata comprises essential information like filenames, permissions, ownership details, file sizes, and other file system requirements. TAR files have gained widespread adoption as a means of storing and transferring files, particularly over the internet.

Creating a TAR file involves amalgamating multiple files into a single archive and subsequently compressing it using compression programs like gzip or bzip2. This compression process significantly reduces the file size, facilitating easier storage and transfer. Extracting files from a TAR archive is accomplished using the TAR program, enabling the recreation of the original files.

TAR files have become a fundamental part of the Linux and Unix ecosystem and are also supported by other operating systems that recognize the TAR format. Their usage extends beyond file management, as software developers frequently employ TAR files to package and distribute their software applications. By bundling all the necessary files and metadata, TAR files streamline the distribution process, ensuring that all components are packaged together for easy installation.

Moreover, TAR files find their place in the realm of data backup. Backup software often employs TAR files to store system backups, capturing all relevant files and metadata required to restore a system to a previous state. The TAR format provides a reliable and efficient method for creating comprehensive backups, safeguarding critical data against loss or corruption.

What is EPUB file format?

The EPUB file format is a free and open standard for digital books and other digital documents. It was developed by the International Digital Publishing Forum (IDPF) to provide a consistent format that can be used across all digital reading devices. EPUB files are based on the Open Packaging Format (OPF) and use a folder structure to contain components such as HTML, attached files, and other resources. EPUB also includes Digital Rights Management (DRM) to protect the files from unauthorized access. EPUB files are designed to be lightweight, compressed and to be reflowable; that is, the text can be adjusted to adjust to the size of a device’s screen. This makes them ideal for mobile devices such as tablets and phones. Furthermore, EPUB files can be read on many popular software e-readers and on most platforms such as Windows, macOS, iOS, Android and Linux. EPUB files contain rich, dynamic interactions and can include tables and diagrams, embedded media, footnotes, and more. They are also highly accessible, allowing people with vision impairments to access the text. Overall, the EPUB file format is a convenient, versatile and accessible way to read digital books and documents, making it an ideal choice for digital publishers.
