What are AVA files and how to open them

Are you having problems opening an AVA file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your AVA files.

What is an AVA file?

An .AVA file is an AvaaBook E-book file.

AvaaBook e-book is a proprietary digital book format made for use with the AvaaPlayer reading application. It serves as a container for distributing Chinese-or Persian-localized e-books over devices supported by AvaaPlayer; publishers use it to package complete books for readers with support for text, images, and sometimes multimedia features.

Production of this format is managed via AvaaBook's publishing services and digital book-store workflows. Once an e-book content (text, layout, images) is prepared by a publisher, it is compiled into the AvaaBook e-book format so that AvaaPlayer can load, present, and optionally synchronize it across devices using AvaaBook's online services. Reading software supports the format on Windows and Android; the content is generally encoded in binary rather than in plain text.

Files in this format begin with the ASCII signature "AVAABOOK" at the very start of the file (that is, offset zero) to identify them.
