Owners of modern smartphones often face a critical shortage of internal storage, especially if the device is initially equipped with a small amount of memory. Installing heavy gaming projects like PUBG Mobile or Genshin Impact instantly fills up the available space, causing the system to slow down and make it impossible to update other apps. Moving data to an external drive becomes the only logical solution for extending the life of a gadget without buying a new one.
The procedure for transferring games to a memory card has changed dramatically over the last years of the evolution of the operating system. If in early versions of Android this was done in a couple of clicks through the standard menu, then modern shells require deeper intervention or the use of special modes for working with drives. Understanding these mechanisms will allow you to effectively manage the file system and free up precious gigabytes.
In this material we will analyze in detail all the available methods for migrating applications, from standard settings to advanced methods using superuser rights. You'll learn why some apps refuse to move, how to properly prepare your SD card, and what risks are hidden behind the memory pooling feature. Get ready to turn your smartphone into a powerful gaming station with no restrictions on volume.
Diagnostics and preparation of an external drive
Before you begin manipulating the file system, you need to make sure that your equipment is technically ready to work with large volumes of data. Not every memory card is suitable for installing modern games, since the read and write speed directly affects the loading time of levels and the absence of freezes during gameplay. Using outdated C4 or C6 class media will result in the game being unstable, even if it is successfully moved.
Pay attention to the labeling of your card: for comfortable work with heavy applications, you need a standard UHS-I or UHS-II with a speed class of at least U3. It is also desirable to have A1 or A2marking, which guarantees high performance when working with many small files, which is typical for application caches. Insert the card into the slot and wait for the system to notify you that the mount has been successful.
The next critical step is to create a backup copy of all data on the card. The process of preparing storage for use with applications often requires a complete formatting, which will permanently delete all photos, music and documents. Copy important information to your computer or cloud storage to avoid losing valuable memories.
⚠️ Attention: If you plan to use the Adoptable Storage feature, the card will be encrypted and linked exclusively to your smartphone. Inserting it into another phone or card reader without formatting will not work - the data will be inaccessible.
Check the functionality of the memory card slot. Sometimes oxidation of contacts or mechanical damage to the slot leads to the system seeing the drive as unstable. In such cases, transferring applications is not possible, since if the connection with the card is lost, all transferred apps will stop running.
Use memory cards with a capacity of 64 GB or higher to install games. A smaller volume will quickly fill up with the cache, and you will again encounter the problem of running out of space.
Standard transfer method through Android settings
The safest and easiest way, available to most users without the need for root access, is to use the built-in application menu. However, it is worth immediately noting that game developers themselves decide whether to allow the transfer of their product to external media. Many online projects block this opportunity to prevent cheating and ensure stability.
To start the procedure, go to the Settings section of your device and find the item Applications or Application Manager. From the list of installed apps, select the game you want to move. If the developer has allowed the migration, you will see an active button Edit or Move to SD card.
Click on the appropriate button and confirm the action. The system will automatically copy the main application files (APK) and part of the data to an external drive, leaving the minimum required set of files in the internal memory for correct operation. The process time depends on the size of the game and the speed of your memory card.
- 📱 Open the settings and select the “Applications” section.
- 💾 Find the game you want in the list and tap on it.
- 🔄 Press the “Storage” button and select “Change.”
- ✅ Confirm the transfer to the memory card in the window that appears.
If the move button is inactive (gray), it means that the developer has strictly limited the installation to internal memory only. In this case, it will not be possible to solve the problem using standard system means, and you will have to resort to more complex methods, which we will talk about below.
Using Adoptable Storage mode
Starting with Android 6.0, Google has introduced a feature that allows you to treat the memory card as an extension of the device's internal memory. This mode, known as Adoptable Storageformats the external drive to the ext4 file system and encrypts it, making it indistinguishable to the system from the built-in memory chip.
Activation of this function usually occurs when the card is first installed. The system will offer two options for use: “Portable storage” (for photos and files) and “Internal memory” (for applications). Select the second option to be able to install any games directly onto the card, ignoring developer restrictions.
If the smartphone already uses the card as portable storage, it will have to be formatted again. Go to Settings → Storage, select your SD card, open the menu (three dots) and click Storage settings. Then select Internal memory and follow the instructions of the setup wizard.
| Characteristics | Portable storage | Internal memory (Adoptable) |
|---|---|---|
| File system | FAT32 / exFAT | ext4 (encrypted) |
| Access from PC | Yes, through a card reader | No, only on this phone |
| Installing applications | Only with the permission of the developer | Any applications and games |
| Performance | Depends on the speed of the card | High, integrated into the system |
After activating the mode, the system may offer to transfer existing data. Agree if the card size is large enough. Now, when installing new games from Google Play, they will be loaded onto the combined drive by default, saving space on the internal chip.
Why do manufacturers disable this feature?
Many brands (Samsung, Xiaomi, LG) programmatically block the ability to format the card as internal memory. They argue that cheap memory cards have low speed and reliability, which can lead to data loss and system crashes.
Advanced transfer via ADB and computer
For users who do not want to format the card or whose smartphones do not support Adoptable Storage out of the box, there is a method using USB debugging. This method allows you to force change the default installation location, bypassing interface restrictions, but requires a computer and minimal technical skills.
You need to activate developer mode on your phone. Go to Settings → About phone and click 7 times on the item Build number. After the message “You have become a developer” appears, return to the main settings menu and find the new section For developers. Enable the option there USB debugging.
Connect your smartphone to computer with a cable and install the ADB (Android Debug Bridge) drivers. Open the command line on your PC and enter the following command to check the connection:
adb devicesIf the device is shown in the list, enter the command to change the default installation location to the external drive:
adb shell pm set-install-location 2Value 2 means the priority of the external card, 0 —automatic selection by the system, a 1 —only internal memory. After executing the command, try installing the game - it should be automatically installed on the SD card.
⚠️ Attention: This method is not a panacea. Some system applications and games with protection will still ignore this setting and install into the internal memory. In addition, after rebooting the device, the setting may be reset on some firmware.
Moving cache and game data folders
Often the main problem of lack of space is not associated with the game installation file (APK) itself, which weighs little, but with cache files (graphics, sounds, levels), which can take up several gigabytes. This data is usually located in a folder Android/obb or Android/data in the internal memory.
Manually moving these folders to a memory card is an effective way to free up space, especially for games that do not support standard transfer. You will need a file manager with access rights to system folders, for example Total Commander or Solid Explorer.
Find the folder with the name of the desired game (usually the developer's domain name, for example, com.supercell.clashofclans) in the Internal Storage/Android/obbdirectory. Cut this folder and paste it into a similar directory on your SD card: SD Card/Android/obb. The folder structure must be completely preserved.
- 📂 Open the file manager and go to the internal memory.
- 📁 Find the folder
Androidand then subsectionobb. - ✂️ Cut out the folder with the specific data game.
- 📥 Paste it into the folder
obbon the memory card.
After moving, launch the game. If the paths are specified correctly, the application will pick up the data from the new location. In rare cases, the game may say that the files are damaged and offer to download them again - then this method did not work for this particular app.
Manually moving OBB folders works for 90% of games, but requires care when maintaining the directory structure. An error in the folder name will result in the game not seeing the cache.
Possible problems and solutions
When optimizing storage, users often encounter various errors, from sudden disappearance of game icons to messages about data corruption. Understanding the nature of these problems will help you quickly return the system to a working state without losing progress.
One of the common problems is when, after transferring, the game stops starting or crashes when loading. This often indicates a low write speed of the memory card or that the system did not mount the drive correctly. Try rebooting the device without removing the card.
If the system writes “The application is not installed” when trying to install it on the card, check the file system format. To work with modern applications, the card must be formatted in exFAT or FAT32 (for portable storage mode). The NTFS file system is often not supported by Android for installing applications.
⚠️ Attention: Never remove the memory card while the phone is on, if there are applications installed on it or the cache has been moved. This is guaranteed to result in read errors and possible loss of game saves. Always use the “Safely Remove” option in the settings.
It is also worth considering that memory cards have a limited rewriting resource. Active installation and deletion of games, constant work with the cache can quickly damage the drive compared to the internal flash memory of the phone. Regularly check the health of the card using special utilities.
Frequently asked questions (FAQ)
Is it possible to transfer game saves to a memory card?
The save files themselves are usually stored either in internal memory in protected system folders, or in the Google Play Games account cloud. Direct transfer of saves manually is only possible on rooted devices or through the backup function if the game supports it. When using the Adoptable Storage mode, saves are moved automatically along with the game.
Why does the game run slower after transfer?
The speed of the game directly depends on the speed of reading data from the drive. The internal memory of smartphones (especially those with the UFS standard) is significantly faster than most microSD cards. If your card has a low speed class, loading textures and levels will take longer, which is perceived as lag.
Will the transfer reset after updating Android?
When updating the operating system version, the storage settings are usually preserved. However, in rare cases, with major updates (for example, from Android 11 to 12), the system may reset permissions or require the card to be re-authorized. It is recommended to have a backup of important data before major updates.
Can you use one card on two phones for gaming?
If the card is formatted as "Internal Storage" (Adoptable Storage), it will be encrypted with a device-specific key and will not work on another phone without formatting (which will delete the data). If the card is in Portable Storage mode, you can move it, but the transferred applications may not launch due to differences in paths and system settings.
How to return everything back to internal memory?
To return applications, go to the card's storage settings and select the "Move data to internal memory" option (if available) or format the card as portable storage. In the latter case, all applications from the card will be deleted and they will have to be reinstalled again, selecting internal memory as the installation location.
