Open OBB File

OBB (Opaque Binary Blob) files are files added to the APK used in the Android application installation process.

APK files store the basic components of an app, while OBB files store all the additional information and data necessary for it to function properly.

They were introduced in Android from version 2.3 Gingerbread of the operating system.

In principle, the OBB files are invisible or unnoticed by the user and are downloaded to the device once the app has been installed.

However, you might find applications that are distributed including OBB files, the so-called XAPK files, and it is even possible to download these OBB files independently.

OBB files can be cached data, explored maps, achieved levels, defeated enemies, special abilities, all this in the case of Android video games.

They are not an app as such, but extra data associated with it.

The OBB files of an app are accessible within an Android device using a file explorer.

In this way it is possible to work with them, copying and pasting them where we need them at any time.

Among the system folders you will find those dedicated to each of the apps you have installed and inside you will find the OBB data in a folder with that name.

You must be careful when handling these types of files, since you could corrupt the installation of your apps and games causing them not to open correctly if you treat them with care.

To manipulate the OBB files you must do it under the Android operating system:
