## What it is
A graphical desktop tool for inspecting Unreal Engine 4 pak and ucas archive files. It shows file trees, size breakdowns, compression details, and internal uasset serialization data, with support for AES-encrypted paks and AssetRegistry.bin loading.

## Use cases
- inspect contents of a UE4 pak file
- analyze which assets take up the most space in a pak
- view uasset import and export tables
- open an encrypted pak with an AES key
- browse cooked game files without the editor
- check compression methods used in a pak archive

## When to choose
- you need a GUI to explore UE4 pak/ucas archives
- you want per-asset size and dependency analysis of cooked content
- you need to inspect encrypted paks with a known AES key

## When to avoid
- you need to create or modify pak files rather than view them
- you work with Unreal Engine 5 pak formats not covered by UE4 support
- you need automated command-line pak processing

## Facets
- artifact type: application
- maturity: active
- function: gui, file-system, compression, developer-tools, parser
- domain: developer-tools, files
- platform: windows, cross-platform, cpp
- tags: unreal-engine, pak-files, uasset-inspection, game-assets, aes-decryption, game-development
