The internal memory of modern smartphones fills up at an alarming rate, especially if you are actively involved in mobile gaming. Heavy projects like Genshin Impact or PUBG Mobile can take up tens of gigabytes, leaving little space for photos and system updates. Fortunately, many devices support the use of external drives, which allows you to relieve the load on the main drive.
However, the process of transferring data is not always intuitive and depends on the version of the operating system and the manufacturer's shell. In this article we will analyze in detail all the available methods, from standard settings to hidden functions for advanced users. You will learn how to properly prepare the media and avoid losing saves in your favorite games.
Preparing the drive and checking compatibility
Before you try to move files, you need to make sure that your device technically supports working with external media as application storage. Not all card slots are designed for installing software; some are designed solely for storing media files.
Insert the microSD card into the appropriate slot on your smartphone. After that, go to the menu Settings and find the section Storage or Memory. Here the system should display information about the built-in memory and the connected external drive.
If the card was previously used in another device or camera, it must be formatted. Please note that formatting will erase all data from the media, so save important photos to your computer or cloud in advance. To work with games, it is best to choose a file system exFATas it supports files larger than 4 GB, which is critical for modern titles.
⚠️ Attention: The speed of games directly depends on the speed class of your memory card. Using a slow card (Class 4 or Class 6) can lead to long loading times for levels and slow graphics.
Use memory cards labeled UHS-I U3 or V30 to ensure maximum speed for writing and reading data in heavy games.
Standard transfer method through application settings
The most a simple and safe method is available directly in the application management menu. This method works on most devices running Android 6.0 and higher without the need to obtain root access or enable complex modes.
Go to the Settingssection, then select Applications. In the list that opens, find the game you want to move and tap on its name. Inside the application menu, find the section Storage.
If the system supports transfer, you will see a button Change or Move to SD card. Click it and wait for the process to complete. The operation time depends on the size of the game and the write speed of your drive.
- 📱 This method is only available for those applications whose developers have allowed installation on external media.
- 💾 Some of the game data will still remain in the internal memory to ensure performance.
- 🔄 When you delete the application, the data from the memory card will also be cleared automatically.
Unfortunately, many popular online games block this function intentionally to prevent cheating or ensure stability. In this case, the transfer button will be inactive or absent altogether.
Activating developer mode for forced transfer
If the standard transfer button is inactive, you can try to bypass the restriction through the developer menu. This feature allows you to force applications to be installed on an external drive, even if the developer did not provide for this.
First, you need to activate the hidden menu. Open Settings and go to section About phone. Find the item Build number and quickly click on it 7 times in a row. The system will inform you that you have become a developer.
Now return to the main settings menu and find the new section For developers. In the list of options, find the parameter Allow saving to external drives or Force allow apps on external. Activate this switch.
Settings -> For developers -> Allow saving to external drives -> ONAfter enabling this option, restart the device. Now, when installing new games, the system may prompt you to select an installation location, and the transfer option may appear in the menu of old applications.
⚠️ Attention: Forced transfer may lead to unstable operation of widgets and notifications from applications, since the external drive is mounted later than the internal memory when the system boots.
Using a memory card as internal memory (Adoptable Storage)
Starting with Android 6.0, a function appeared that allows format the memory card as part of the internal storage. In this case, the system encrypts the drive and combines its space with the main memory of the phone.
To activate this mode, go to Settings -> Storage. Select your SD card, click on the menu (three dots) and select Storage settings. Next, select the option Internal memory.
The system will warn you that the card will be formatted and will become inaccessible to other devices without resending formatting. Confirm the action and wait for the data migration to complete. After this, new games will be automatically installed on the combined volume.
| Characteristics | Portable storage | Internal memory (Adoptable) |
|---|---|---|
| Access from PC | Yes, as removable disk | No, only via phone |
| Encryption | Not necessary | Required |
| Transfer of applications | Partial or manual | Automatic |
| Risk of data loss | Low | High when retrieving |
This method is most effective for owners of devices with a small amount of built-in memory, for example, budget models from Xiaomi or Samsung series A. However, you cannot remove such a card without losing access to applications.
What to do if the "Internal memory" option is missing?
Some manufacturers (for example, Sony or Samsung in new models) programmatically hide this function. In such cases, it can only be activated through a computer using ADB commands, which requires some technical preparation.
Transferring cache files and Obb folders manually
Sometimes the application itself is transferred, but its heavy resources (cache, textures, maps) remain in the internal memory. This often happens with games that have additional data downloads. You can solve the problem by manually moving folders.
You will need a file manager with access to system directories, for example Total Commander or MT Manager. Find the folder Android/obb in the internal memory. Inside you will see a directory with the name of the game package (for example, com.supercell.clashofclans).
Cut this folder and paste it into a similar directory on the SD card: /storage/sdcard1/Android/obb/. The exact path may vary depending on the device model, so check the displayed path in the file manager.
- 📂 Make sure that the folder structure on the card memory is completely identical to the original one.
- 🛑 Do not launch the game while moving files to avoid damage to the archives.
- 🔍 After the transfer, check that the game sees the files and does not start downloading them again.
Manually moving the cache requires care. If you make a mistake in the path or folder name, the game simply does not work. will start or display an error loading resources.
Manually moving Obb folders can free up up to 80% of the space occupied by the game, even if the transfer button in the settings is inactive.
Possible problems and solutions
During the process of optimizing storage, users often encounter errors. The most common problem is that the game stops working. start after the transfer. This is usually due to the fact that the application has lost access rights to the new path or the memory card has been removed.
If the game crashes immediately after launch, try clearing its cache in the application settings without deleting the data itself. Sometimes restarting the device again helps so that the system correctly mounts the external drive.
Another common situation is that the memory card is detected as damaged. This may indicate a physical failure of the media or file system incompatibility. Try to format the card again directly through the smartphone settings, and not on the computer.
⚠️ Attention: Menu interfaces and item names may differ on smartphones of different brands. Always check the current paths in the official documentation for your device model.
☑️ Diagnosing problems with the card
Frequently asked questions (FAQ)
Is it possible to transfer games to a card without formatting the phone?
Yes, in most cases There is no need to format the phone itself. It is enough to format only the memory card. However, when using the "Internal Memory" mode, the data on the card will be deleted.
Why does the game run slower after the transfer?
The data reading speed of memory cards is usually lower than that of the phone's built-in flash drive. If the card has a low speed class (below U3), this will inevitably lead to longer loading times for levels.
What will happen to games if I remove the SD card?
Applications installed on the card will no longer launch, and their icons may disappear from the desktop until the drive is reinserted. The data is not deleted, but access to it is blocked.
Is it possible to transfer system applications to the card?
No, system applications and services necessary for Android operation must remain in the internal memory to ensure the stability of the operating system.
