Paper: Understanding the Windows Phone XAP Archive Format and Its Full Extraction

Abstract

This paper explains the structure, purpose, and extraction of Windows Phone XAP archives, focusing on how a "full" XAP (including all dependencies, native libraries, and metadata) is organized and unpacked. It covers technical internals, tools and methods for extraction, use cases (debugging, migration, security analysis), limitations, and best practices for handling XAP files.

Key components of a XAP file

• Windows Phone 7 (WP7)
• Windows Phone 8 (WP8)
• Windows Phone 8.1

• Nokia Here Drive+ – Offline navigation that still works in 2025 (GPS satellites don't expire). The XAP contains map data from 2016.
• 6tag (by Rudy Huyn) – The definitive Instagram client, superior to the official app.
• MetroTube – A YouTube client with a better UI than Google's modern app.
• MoliPlayer Pro – The only video player that handled MKV and AC3 audio.
• Adobe Reader (Nokia Edition) – Incredibly fast PDF rendering.
• The "Extras & Info" – The hidden diagnostic XAPs that let you run LTE-only mode or test vibration motors.
