Line 82:

A basic package contains an XML file called ''[Content_Types].xml'' at the root, along with three directories: ''_rels'', ''docProps'', and a directory specific for the document type (for example, in a .docx word processing package, there would be a ''word'' directory). The ''word'' directory contains the ''document.xml'' file which is the core content of the document.

; [Content_Types].xml: This file provided MIME type information for parts of the package, using defaults for certain file extensions and overrides for parts specificiedspecified by [[Internationalized Resource Identifier|IRI]].

; _rels: This directory contains relationships for the files within the package. To find the relationships for a specific file, look for the ''_rels'' directory that is a sibling of the file, and then for a file that has the original file name with a ''.rels'' appended to it. For example, if the content types file had any relationships, there would be a file called ''[Content_Types].xml.rels'' inside the ''_rels'' directory.

; _rels/.rels: This file is where the package relationships are located. Applications look here first. Viewing in a text editor, one will see it outlines each relationship for that section. In a minimal document containing only the basic ''document.xml'' file, the relationships detailed are [[metadata]] and ''document.xml''.
