APK OBB Download Guide: How to Install APK with OBB Data Files (2026)

Large Android games—think Genshin Impact, Call of Duty Mobile, Asphalt, or FIFA—don't come in a single APK file. They're split into two parts: the APK (the app itself) and one or more OBB files (the game assets: graphics, audio, maps, and data).

If you're sideloading a game, installing the APK alone won't work. You need to place the OBB files in the correct folder. This guide covers everything about APK + OBB downloads and installation in 2026.

What Is an OBB File?

OBB stands for Opaque Binary Blob. It's a file format Android uses to store large game assets separately from the main APK. This split serves two purposes:

APK size limits: Google Play Store has a 200 MB limit for APK files. Games can be 2–10 GB, so the extra data goes into OBB files
Flexible updates: Developers can update the APK without requiring users to re-download gigs of game data

OBB files are typically named with a specific pattern: main.<version>.<package-name>.obb (required) and patch.<version>.<package-name>.obb (optional).

How to Download APK + OBB Files

Step 1: Find a Reliable Source

Not all APK download sites include OBB files. When downloading large games, look for sources that explicitly mention "APK + OBB" or "APK + Data."

Using a Google Play APK downloader like gptoapk.com gives you the authentic APK, but for OBB files specifically, you may need a site that also archives game data files. Some popular sources in 2026 include:

APKMirror — Good for original APKs, but doesn't always host OBB files
APKPure — Includes OBB files for many games
Revan Online — Specializes in game data files

Step 2: Download Both Files

You'll typically download:

The APK file (usually 50–200 MB)
One or more OBB files (can be 500 MB to 5+ GB)

Make sure you get the correct version—the APK and OBB versions must match exactly, or the game won't launch.

Step 3: Transfer to Your Device

If downloading on your phone, both files should already be in your Downloads folder. If downloading on a PC, transfer them to your Android device via USB cable, WiFi transfer, or cloud storage.

How to Install APK with OBB Files

Method 1: Manual Placement (Most Reliable)

Install the APK first — Tap the APK file to install it. Don't launch the app yet
Create the OBB folder — Using a file manager, navigate to Android/obb/ on your device's internal storage
Find the package name — Look for a folder named after the game's package name (e.g., com.gameloft.game). If it doesn't exist, create it
Move the OBB file — Copy the .obb file into Android/obb/<package-name>/

The final path should look like:

Internal Storage → Android → obb → com.example.game → main.100.com.example.game.obb

Package Name	OBB Folder Path
com.supercell.clashofclans	Android/obb/com.supercell.clashofclans/
com.miHoYo.GenshinImpact	Android/obb/com.miHoYo.GenshinImpact/

Launch the game — If everything's in the right place, the game should detect the OBB data and load normally

Method 2: Using an APK + OBB Installer App

Apps like APK Installer or SAI (Split APKs Installer) can automate OBB placement. Some file managers (like Solid Explorer or FX File Explorer) also handle OBB installation automatically.

Download both the APK and OBB files to your phone
Open the file manager
Tap the APK file
The app may prompt you to locate the OBB file—navigate and select it
Wait for the installation to complete

Common OBB Issues and Fixes

Issue	Cause	Fix
Game loads but has missing textures	Wrong OBB version	Match APK and OBB version numbers
OBB file won't copy	Insufficient storage	Free up space on internal storage
Game doesn't show up after install	Package name mismatch	Check folder name matches exactly
"App not installed" error	Incompatible architecture	Download correct ARM/x86 variant

Internal Storage vs SD Card

Most OBB files must be placed on internal storage, not an SD card. Android's default OBB path (Android/obb/) is always on internal storage. If your device supports "adoptable storage," the SD card may be merged, but for OBB files, always use the internal storage path.

Some devices running Android 11+ allow folder mounting tricks, but for the vast majority of users, internal storage is the only option.

Do You Need OBB Files for All Games?

No. Many modern games download their data files on first launch directly from the Play Store or the developer's servers. You only need manual OBB files when:

You're sideloading a game (not using Play Store)
You want to skip the in-game download (saves time and data)
The game is no longer available on the Play Store
You're installing a modded APK that requires specific data files

FAQ

Can I delete OBB files after installing a game?

No. The game needs the OBB files every time it runs. Deleting them is like removing a PC game's installation folder—the app itself may still be installed, but it won't have any assets to load.

Why do some games use multiple OBB files?

Some games split their assets across multiple OBB files for organization or update purposes. A typical setup is main.obb (core content) and patch.obb (updates or DLC). Both need to be in the same folder.

How do I find the package name for the OBB folder?

After installing the APK (but before launching), check the folder names inside Android/obb/. The new folder will match the app's package name. Alternatively, look up the app on Google Play—the package name is in the URL: play.google.com/store/apps/details?id=<package-name>.

Final Thoughts

Installing APK + OBB files is straightforward once you understand the folder structure. The most common mistake is placing the OBB file in the wrong location. Always double-check the Android/obb/<package-name>/ path, ensure the OBB filename matches exactly, and you'll have your game running in minutes.
