XFF - MajickTek/XFF-SPEC GitHub Wiki

The actual eXtensible File Forma itself is an empty binary file, and is the simplest file to create.

The file structure is like this:

HEADER
{
  signature U24
  version U8
}

FILE
{
  header HEADER
}

This is the base structure of all the other files in this wiki. this file will be extended in all directions, hence the name "extensible file format".
