If you’re downloading apps or games from namoapk.com, you’ve likely come across different file types like:

  • .apk
  • .xapk
  • .apks
  • .obb

But what do they all mean? And how do you install each of them?

In this ultimate 2025 guide, we’ll break down the differences, use cases, and installation methods for each Android file type — so you can install any MOD or premium game like a pro.

1. What Is an APK File?

APK stands for Android Package Kit. It’s the most common file type for installing Android apps.

🔍 Key Features:

  • Single file format (appname.apk)
  • Contains code, resources, manifest, and assets
  • Can be installed by simply tapping it
  • Used for both MOD and official apps

Best For:

  • Simple apps
  • Lightweight MODs
  • Manual installs on Android 6.0 – Android 14+

2. What Is an XAPK File?

XAPK is a compressed package that includes:

  • The main APK file
  • One or more OBB (game data) files

XAPK = APK + OBB in one installable ZIP format.

XAPK files can’t be installed directly. You need a dedicated installer like XAPK Installer, APKPure App, or ZArchiver.

🧱 Example File Structure: com.pubg.global.xapk
├── com.pubg.global.apk
└── Android/obb/com.pubg.global/main.obb

Best For:

  • Large games (1GB+ size)
  • Apps with extra assets or game data
  • MOD APKs with built-in data

3. What Is an APKS File?

APKS stands for Android App Bundle Split APKs.

When developers upload AAB files to Google Play, it’s split into:

  • base.apk
  • config.architecture.apk
  • config.language.apk
  • resources.apk, etc.

The .apks file bundles all of these into one.

You can’t install .apks by tapping it. Use SAI (Split APKs Installer).

Fun Fact:

Google Play now installs apps as Split APKs, which is why you need .apks for many newer apps.

Best For:

  • Newer Android apps (especially post-2022)
  • Multi-language or architecture-specific apps
  • Complex MODs with full feature sets

4. What Is an OBB File?

OBB = Opaque Binary Blob – basically, extra game data.

It’s not an app but used by large apps/games to store:

  • Graphics
  • Maps
  • Audio
  • Levels

You usually see OBB paired with an APK or XAPK file.

Install Path:

Move OBB files to: Android/obb/com.app.package.name/

Example: Android/obb/com.rockstargames.gtasa/main.obb

Best For:

  • 3D games
  • Offline games with HD graphics
  • MOD APKs that require large data files
