.OBB option no.
File used by some Android applications sold on the Google Play online store; contains additional application data that is not stored in the main application package (.APK file), such as graphics, media files, or other large software assets; uses an encrypted format. More information
Since Google Play only allows APK files to be 50MB or less in file size, app developers must use different files to store additional app assets. Developers can use any format they choose, such as .ZIP or .MP4, but they can also use the JOBB tool that comes with the Android SDK to bundle and encrypt assets together in an OBB file. These additional assets can be downloaded via an APK file using the Google Play Developer Console, and users who download the app will receive an APK file and additional asset files.
NOTE. Any additional asset provided outside of the APK file is called an APK extension file.
Programs that open OBB files
Hi all. We are studying Android and everything inside it, and as we already know, there may be incomprehensible programs, incomprehensible folders... Today we will find out about such a folder as obb, we will find out what it is for. Well guys, I went to the Internet. And here’s what I found out: the obb folder is used to store cache files, which also have the .obb extension, and this folder is usually located in this path: sdcard/Android/obb. I also read that this folder may be missing, and as a result there may be problems when installing applications that need a cache. And I read that in this case you need to create it manually (maybe you should use some kind of file manager for this), because most programs for cache files use the obb folder. Well, that is, the obb folder turns out to be a program cache =)
sdcard/Android/obb/com.NameApp/com.NameApp.obb
Where NameApp is the name of the application or game. And by the way, this cache can be opened using WinRAR. But I also read that if the program cache is very large, then it comes in compressed form and when unpacked, it extracts the files into this folder:
sdcard/Android/data/com.NameApp
Wow, I’m reading this here, in short, this cache may have another purpose - license checking. And the joke is this: for example, you launch the game and it cannot find the cache in the desired folder, while the cache itself can only be downloaded from Google Play (I’ve never even heard of this), what’s the result? The game's protection may work because you didn't buy it if the cache is not in the right folder! In short, guys, something like this, excuse me if something is wrong, it’s hard for me to understand this whole thing.
Well, here are two pictures for you to say on topic:
By the way, about what a cache is, I found the following information:
In general, guys, to the question what kind of obb folder is there, there is only one answer - it’s a cache for applications, including games. Applications in the obb folder have their own folders in which the cache is located, which seems to come in the form of one file with the extension .obb =)
That's all, otherwise I'm already a little confused here. Good luck and be happy!!
Today's article on Android will be useful for those who like to play paid games for smartphones and tablets for free. When installing paid content, certain difficulties may arise, for example, there is no config, driver, required codec, or simply root rights or simply the required directory or folder. To install games with cache, you need the obb folder in Android. Let's talk about her.
How to properly unpack the cache?
Select the archive by long pressing → “ Unpack”
in" and select the directory /
Android
/obb (sometimes this is /sdcard/
Android
/obb). The same can be done in another way if you use an alternative file manager: unpack the archive in the folder where it is located; com folder

The obb folder (sdcard/Android/obb) on Android, what is it for?
A little theory to get started so you can show off in front of your friends. This directory in the system is used to store files with the extension “.obb”. Usually a cache of various applications or games is stored there. There are two main ways to install new software on a phone or tablet:
- Installation directly from Google Play. The only thing you need is a Google account
- Downloading APK and all necessary files to the device and subsequent installation directly from the smartphone;
There are no difficulties with the first method; with the second, things are somewhat different. There are paid games and apps that we want to play and try for free. They often contain cache data, for example, to install GTA San Andreas on your phone, you need to download along with the APK the folder with the game cache, which is installed in the obb folder. When purchasing and subsequently installing the official application, the obb folder is created itself. When downloading a pirated version of the phone, the obb folder is initially missing, into which you need to throw the cache for games.
Installing DATA caches on Android 11 and higher
To gain access to the data folder, you will need another application called Files. It works great on a lot of smartphones, but there are exceptions everywhere. This does not guarantee access to the data folder. If suddenly access to the data folder is limited, try performing all the steps as with the X-plore
.
From these instructions you can understand that installing caches on your phone is not so easy if you have Android version 11. But there are working solutions. Keep in mind that this may not work on some devices, and installed caches will still prevent the game from running. This is real “dancing with tambourines.” So cross your fingers and hope for the best 
What to do if there is no directory, sdcard/Android/obb folder?
As the inquisitive reader guessed, this folder just needs to be created. We recommend creating it in the smartphone’s memory, because... By default, all games and programs are installed there. If you install utilities on an SD card, create them on a flash drive. The first option is to create a folder directly from your smartphone:
- Open any file manager (every device has a built-in one).
“Android” is a system folder, so it can be hidden. If it is not visible, click on the context menu button and select “Show hidden files and folders”; Show hidden files or folders - Go to the “.android” folder, click the “new folder” icon and write the name “obb”;
How to create obb folder
The second option is to pick up a USB cable and connect to the computer. We follow the same path - open the desired disk, go to the android folder, create the obb folder. Now, after installation, we throw the cache files there and enjoy our favorite games.
Attention! Do not launch the game until you have copied all the necessary cache files, otherwise you will have to repeat the installation process again.
In relation to the Android operating system, files in the obb act as a container for resources necessary for the launch and correct operation of some programs and game projects. Such files are installed in the appropriate directory and used as needed. As you know, there are two ways to install content on an Android device - using the Google Play service, which requires a Google account, or from third-party resources - in this case, the user has to independently send the downloaded cache to the appropriate folder in the device’s file system.
In the first case, all processes occur automatically - the necessary folder is created where the cache is transferred. Things are much more complicated when the user installs the software independently. For example, wanting to install the game Assassin's Creed: Rebellion on your device, a gamer needs to download a package consisting of an installation APK file and a cache, the latter should take its place in the obb folder. But sometimes such a folder simply does not exist in the file system, so you need to create it yourself.
Creating the obb folder directly from your mobile device:
- We use any File Manager (you can use pre-installed software).
- We are looking for the “Android” system folder, which can sometimes be hidden, so we will use the “Show hidden files and folders” option.
- Go to the “.android” folder, tap the “new folder” icon and call it “obb”.
Creating the obb folder using a personal computer:
- We connect the mobile device to the PC using a USB cable.
- We go to the required drive, look for the android folder and create a new folder there, “calling” it obb.
Now, having installed the game, we send the downloaded cache to the created obb folder (after unzipping it) and enjoy the exciting gameplay. Remember, after installing the game, you cannot launch it until the cache is placed in its “rightful” place!
The table below provides useful information about the .obb file extension. It answers questions such as:
- What is an .obb file?
- What software do I need to open the .obb file?
- How can a .obb file be opened, edited or printed?
- How to convert .obb files to another format?

Is it possible to transfer game cache from Android phone memory to an external drive?
If you need to transfer buffer data from internal storage to a memory card, then you need to do the following:
- Get root rights. However, it is not recommended for users who do not understand the device to do this.
- Download the FolderMount app.
- Launch the utility. Click on the “+” in the upper right corner of the screen.
- A window will open with three input fields. Where it says “Name” you must enter the name of the game. In the “Source” field, you need to select the directory where the cache is installed on the internal memory. The last line is “Destination”. In it you need to enter where to transfer the buffer data (to SD).
- When all the information is filled in, you need to click on the checkmark at the top, then on the pin next to the list item.
Program interface for transferring cache to a flash drive
Important! If you install root rights incorrectly, there is a risk of damaging the device or voiding the warranty on the gadget. Therefore, you need to be careful; you should also not download special utilities from unknown platforms or forums.
Some games do not work without cache, so you need to download it separately. However, simply uploading a file is not enough. You need to know how to unpack folders and where to put them. The instructions described above will help you solve this. The main thing is to first look at all the information on the website with the file.
