Notes about the EPUB file extension:

Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The EPUB file type is primarily associated with 'Open Publication Structure' by International Digital Publishing Forum (IDPF). .EPUB is the file extension which refers to two open standards, the Open Publication Structure (OPS) and Open Container Format (OCF), produced by the IDPF. .EPUB allows publishers to produce and send a single file through distribution and offers consumers interoperability between software/hardware for unencrypted reflowable digital books. OEB, originally produced in 1999, is the precursor to OPS. .EPUB files are a ZIP file with XML/HTML eBook content along with a XML file describing the contents. You can use the Adobe Digital Editions program to read these files.
