Notes about the EPUB file extension:



Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

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.
