Some Android MOD APKs come with an extra file called an OBB. If you just install the APK without this data file, the app may crash, freeze, or not open at all.
In this quick tutorial, we’ll explain:
- What OBB files are
- Why they matter
- How to properly install them alongside a MOD APK
Let’s go step by step.
What Is an OBB File?
OBB stands for Opaque Binary Blob. It’s a file format used by Android apps (mostly games) to store large amounts of data like:
- Graphics & 3D assets
- Music & voice files
- Cutscenes & videos
- Maps or game levels
An OBB file is always used along with an APK — it won’t work on its own.
Where Are OBB Files Stored?
On most Android phones, OBB files are stored here:
/Android/obb/[package-name]/
Example for PUBG Mobile:
/Android/obb/com.tencent.ig/
The OBB must go into a folder named exactly like the package name of the APK.
How to Install MOD APK + OBB Correctly (No Root)
Step-by-Step:
- Download the MOD APK + OBB ZIP File
- From a trusted site like namoapk.com
- Extract the ZIP File
- Use a file manager like ZArchiver or RAR
- You’ll get:
- One
.apkfile - One
Android/obb/folder
- One
- Move the OBB Folder
- Copy the OBB folder to your phone’s internal storage:
>/Android/obb/[package-name]/
- Install the MOD APK
- Tap the
.apkfile and install normally - If it says “App Not Installed,” check our fix guide
- Open the App
- If the OBB is in the right place, it will work perfectly!
