Many users of the Android operating system are faced with the need to find the installation file of an application that is already running on their device. This may be required to create a backup copy, transfer the app to another gadget without access to the Internet, or to analyze malicious code. However, the standard file manager often hides system directories, and the data storage architecture in Android itself has undergone significant changes in recent versions.
The question of where they are physically located APK filesdoes not have a clear answer for all devices. The location depends on how the application was installed - from the official store, through a third-party site, or whether it was part of the firmware. In addition, access rights to some sections of the file system are limited, which requires the use of special tools or obtain root access. In this article we will analyze in detail all possible locations and methods for extracting installers.
Understanding the structure of the file system Android is critical for a correct search. You should not look for files in the “Downloads” folder if the app was downloaded from Google Play —only those files that you downloaded manually through the browser are stored there. System data is distributed over special service partitions, access to which is regulated by the operating system kernel.
Main directories for storing system applications
Initially, in early versions of Android, all applications were installed in one common folder. Today, the system differentiates between user and system apps to ensure security and stability. If you are looking for where pre-installed app files such as phone, messages or settings are stored, you need to look at /system.
There are several key subfolders within this directory. The folder /system/app contains basic applications that are part of the operating system and cannot be removed by standard means. Here are APK files of a calculator, calendar, clock and other utilities built in by the manufacturer.
For apps that were preinstalled by the smartphone manufacturer, but theoretically can be deleted by the user, a different directory is allocated. This is the folder /system/priv-app. It houses critical services such as system settings, application store and services Google Play Services. Access to these files is only possible with superuser rights.
⚠️ Attention: Any attempts to manually delete or change files in the folder
/systemmay result in the device not working (bootloop). Do not manipulate these directories without creating a full backup.
It is important to note that in modern versions of Android the structure can be more complicated. Inside the app i priv-app folders, subdirectories are often created with the names of specific packages, where the APK file itself, as well as the libraries and resources associated with it, is located. Simply copying the file from here may not be enough to install on another device, since dependencies may be missing.
Custom application location
When you download and install a app from the store Google Play or other source, it ends up in the user section of memory. The main storage for such applications is located along the path /data/app. This is the main directory where the system places APK files of all third-party apps.
Starting with Android 6.0 and higher, the structure of this folder has changed. Now, for each application, a unique subfolder is created with the name type com.example.app-Base64String. Inside this folder there is a file base.apk, which is the installation package. Previously, files could be located directly in the root of the directory /data/app with the extension .apk.
In addition to the main file, optimized versions of the code (.odex or .vdex files) and native libraries (.so) necessary for the app to run on a specific processor. This is designed to speed up the launch of applications, but complicates the process of simply extracting a clean APK. oat And lib optimized versions of the code (.odex or .vdex files) and native libraries (.so) necessary for the app to run on a specific processor are stored. This is designed to speed up the launch of applications, but complicates the process of simply extracting a clean APK.
It is worth remembering that the folder /data is by default hidden from viewing by regular file managers. To see its contents, you will need a file manager with root access support, for example Root Explorer or Solid Explorer with privileges enabled. Without these rights, you will not even be able to open this directory.
Temporary files and installer cache
In addition to the main system partitions, there are temporary storages where APK files can be located during the installation or update process. When you download an application through a browser or instant messenger, the file is first saved to a public memory area, usually in a folder /sdcard/Download or /sdcard/Android/data/....
The system batch installer also has its own temporary directory. The path /data/app-staging is used by the system to prepare the application for installation. The files are located here for a short time until the signature is verified and the process of copying to the main directory is completed /data/app.
Sometimes users find the remains of APK files in the cache of application stores. For example, in older versions Google Play you could find the cache in the folder /sdcard/Android/data/com.android.vending/cache. However, now these files are often encrypted or have complex names, which makes them unsuitable for direct use without additional processing.
Why are cached files not suitable for installation?
Cache files are often not full APKs, but parts of them (split APKs) or encrypted data that the system collects together only at the time of installation. Trying to install such a file manually will result in a package parsing error.
If you are looking for a file that you downloaded but did not install, check your standard downloads folder. If the installation was successful, the original downloaded file may have been automatically deleted by the system to save space, especially if the browser's built-in downloader was used.
How to extract an APK using the ADB command line
For advanced users who do not want to root their device, there is a reliable way to find the path to the APK file and extract it using the tool Android Debug Bridge (ADB). This method works on any device with USB debugging enabled.
First you need to find out the full path to the file of the application you are interested in. To do this, use the command pm path, which displays the location of the package. By executing the command in the terminal of a computer connected to the smartphone, you will receive a response like package:/data/app/com.example.app-xyz/base.apk.
adb shell pm path com.example.package.nameAfter receiving the path, you can copy the file from the device to the computer using the command adb pull. This will create an exact copy of the installed APK file on your hard drive. This method is the cleanest, since you get exactly the file that is currently being executed by the system.
adb pull /data/app/com.example.app-xyz/base.apk C:\backup\app.apk☑️ Preparing for extraction via ADB
The advantage of this method is that it does not require violating the device warranty or unlocking the bootloader. You work with the file system at the shell user level, which is allowed to read most open application files.
Using third-party applications for backup
If working with the command line seems too complicated for you, there are specialized applications that automate the process of finding and extracting APKs. apps like APK Extractor or Swift Backup scan installed packages and allow you to save their installation files to internal memory or the cloud.
These utilities can work with both regular APKs and modern packages Split APKs (XAPK, APKS). They correctly collect all the necessary parts of the application into one archive or file, ready for installation. This is especially true for modern applications that use resource division by screen density and language.
| Utility name | Root required | Split APK support | Export to the cloud |
|---|---|---|---|
| APK Extractor | No | Partially | No |
| Swift Backup | Yes (full functionality) | Yes | Yes |
| Send Anywhere | No | Yes | Via P2P |
| App Backup & Restore | No | No | Yes |
When using such apps, it is important to pay attention to the permissions they request. To work correctly, they need access to the list of installed applications and the right to write to the internal memory. Some features, such as saving app data along with the APK, will only be available on rooted devices.
When extracting Split APKs, make sure you copy all parts (.apk, .xapk), otherwise you will get an "App not installed" error when installing on another device.
Storage features in Android 10 and later
With the release of Android 10 and subsequent versions, Google has tightened its file system access policy by introducing the concept of Scoped Storage. This means that applications no longer have free access to the entire file system, but only operate in their own isolated sandboxes.
This change indirectly affected APK storage. Although system paths /data/app remain the same, access to them for third-party file managers without root access has become almost impossible through the standard API. Now even advanced file managers may not display the contents of system folders.
In addition, many modern applications are distributed in the format Android App Bundle (.aab). Such files are not installation files in themselves and are not stored on the device in finished form. The store Google Play generates an optimized APK from the .bundle directly upon download, and this generated file is then placed in /data/app.
⚠️ Attention: Interfaces and access paths may change with firmware updates from manufacturers (Samsung, Xiaomi, Pixel). If you cannot find the file in the specified path, check the current structure in the documentation for your specific model or version of Android.
Users who want to save a copy of such an application are recommended to use extraction methods via ADB or specialized backup utilities that can reconstruct the package from installed components, since it is impossible to find the original .aab file on the device.
On modern versions of Android without root access, the only reliable way to get the APK of an installed application is to use the ADB command "pm path" and then copy it.
Frequently asked questions (FAQ)
Can I find the APK file in the Download folder after installing from Google Play?
No, this is impossible. When installing from the Google Play Store, the file is downloaded to a temporary system cache, installed, and then the original downloaded file is deleted to save space. Only those APKs that you downloaded manually through the browser remain in the “Downloads” folder.
Why don’t I see the /data folder on my phone?
The folder /data is system and hidden. Access to it is closed to regular applications for security reasons. To see its contents, you need a file manager with support for root access (superuser rights) or a connection to your computer via ADB.
What is the difference between the files in /system/app and /data/app?
The folder /system/app stores pre-installed system applications that are part of the firmware. The folder /data/app contains all the apps that the user installed independently while using the device.
Is it possible to simply transfer an APK from /data/app to another phone?
Yes, in most cases this will work for regular APKs. However, if the application uses Split APKs or depends on your processor's specific libraries, a simple copy of the main file may not run. It is better to use the “Share” function or export via special. utilities.
Where is application data stored, and not the installation files themselves?
Application data (settings, cache, databases) is stored in the directory /data/data/[package_name]. This folder is strictly protected, and only the application itself and a user with root access can access it. These files cannot be viewed using conventional means.
