An .obb file is an expansion file used by some Android apps distributed using the Google Play store. It contains data not stored in the application’s main package (. APK file), such as graphics, media files, and other large program assets. For example, a game such as Free Fire has a 20 MB .apk file but it may install additional data ranging from a few hundred MBs to a GB or more in an .obb file after it launches.
How to install apk file with OBB:
If you’ve downloaded an APK or a game that requires OBB files, you’ll need to install them manually. The first step is to download ES File Explorer to your phone. Once the app is installed, double-click the file, then open it. Look for the OBB Archive, then click it. After the file has been installed, you’ll need to copy the OBB file into the same folder as the APK.
Next, you’ll need to create an OBB subfolder. In Android, this is usually located in the Android folder in your phone’s SD card. To create this folder, go to your phone’s Settings and select “Unknown Sources.” When prompted, tap the clipboard button, then choose “Paste” to paste the file into your Android device. Once you’ve done that, you can now install the game.
After you’ve copied the OBB file to your phone, make sure to rename the folder. Then, you’ll need to locate the package name of the app. You can find this by referencing its url in the play store. Then, copy the OBB file to the Android/Obb folder in the external memory. You can now install the game. It’s that easy!
