'\x00\x00\x00\x00\x00\x00\x00\x00' might possibly be a File Signature.

File signatures are data used to identify or verify the content of a file. Such signatures are also known as 'magic numbers'.

Example: ico 00 00 01 00
Example: jpg FFD8
Example: pdf \x25\x50\x44\x46


It is possible that the extension is .mobi but it is not at all a real .mobi file.

What I suggest is to open the binary ebook file with a text editor (e.g. Notepad), and inspect the first line for an indication of what the file type really is.

A few examples from one of my libraries:

epub: mimetypeapplication/epub+zip PK

mobi: BOOKMOBI

pdf: pdf

cbz: PK


Based on what you find, try renaming the file extension to what it seems to really be, and opening it with an application that can open that file type.
