Smartphone owners Samsung Galaxy often face a lack of free space in the internal memory. It's an inevitable process: apps update, cached data accumulates, and high-resolution photos and videos take up gigabytes. When your device starts to slow down or display low-space notifications, the smartest solution is to use an external drive.
Moving data to an SD memory card not only frees up valuable space, but also protects important information. In the event of a system failure or breakdown of the smartphone itself, files stored on removable media will remain intact. Modern models, such as Samsung Galaxy A54 or S23 Ultra, support large-capacity cards, turning the phone into a powerful multimedia center.
However, simply inserting a flash drive is not enough. To work correctly, you need to properly configure the system, select the appropriate file format, and understand the difference between moving media and installing applications. In this guide, we will analyze in detail all the stages of data migration so that your Android works quickly and stably.
Preparing the memory card and slot
Before you start the transfer, make sure that your memory card is compatible with the device. Smartphones Samsung usually support standards microSD, microSDHC i microSDXC. It is important to check the maximum supported capacity listed in your model's specifications, as using a card with a larger capacity may result in read errors.
Insert the card into the dedicated tray. Most modern models Galaxy use a hybrid slot, where the memory card shares space with the second one. SIM card. Be careful when installing: incorrect orientation of the chip may damage the contacts. After physical installation, the phone should recognize the drive automatically.
⚠️ Attention: If the phone does not see the card immediately, do not try to remove it by force. Try rebooting your device. If the problem persists, check the card contacts for oxidation or dust.
The system will prompt you to configure the card. You can use it as portable storage or as part of your internal memory. The first option is preferable if you plan to change cards frequently or connect them to a computer. The second option (Adoptable Storage) encrypts the card, making it unreadable on other devices without unlocking.
Use U3 or V30 speed class memory cards to record 4K video. Slow cards will cause delays when shooting and opening heavy files.
Setting up storage in the Android system
After installing the drive, you need to go to the system settings. Go to menu Settings → Device maintenance → Memory. Here you will see detailed statistics on the use of internal space and the newly connected SD card.
Click on the name of your memory card. The system will prompt you to format it. This process will delete all datamay have already been written to the card previously, so make a backup copy of important files on your computer before starting setup. Formatting is necessary to create a proper file system that Android can understand.
- 📁 Select the “Format as portable storage” option if you want to store photos and music.
- 🔒 Select “Format as internal memory” if you want to install applications directly on the card (not available on all models).
- ⚙️ After formatting, the system will assign a unique name to the card, for example,
SD Card 1.
Now the card is ready for use. It will appear as a separate section in the file explorer. You can start moving files manually or set up automatic saving of new data.
Moving photos and videos through the Gallery
The most voluminous content on a smartphone is the media library. The easiest way to move already taken pictures and videos is through the standard application Gallery. Open the application, pinch one photo to select it, then select the rest of the files or click “Select All” in the menu.
Click on the menu icon (three dots) and select “Move”. The system will prompt you to select a destination. Specify your SD card and create a new folder there, for example Archive_Photos, so as not to mix old and new pictures. The copying process will take time depending on the amount of data.
| File type | Average size | Recommended action | Transfer priority |
|---|---|---|---|
| Photo (JPEG) | 3-5 MB | Move to archive | High |
| Video (Full HD) | 100-300 MB | Move to SD | Critical |
| Video (4K) | 500+ MB | Leave on fast media | Medium |
| Screenshots | 1-2 MB | Delete or move | Low |
It is important to note that after moving, files in the gallery may temporarily disappear from the general feed. Don't panic, they are in a new folder on your external drive. You can open them through the app My files in the "Memory Card" section.
Why is it better not to transfer 4K video?
Ultra high definition video requires high reading speed. Cheap memory cards may not provide the required data flow, which is why the video will slow down during playback.
Transferring applications and games to a memory card
The issue of transferring installed applications (APK) to a memory card is one of the most difficult in the Android ecosystem. Starting with Android 6.0, Google has limited this feature to ensure system stability. However, on smartphones Samsung some of the functions are retained.
Go to Settings → Applications. Select the desired app from the list. If the developer has allowed the transfer, you will see an active Edit button in the Storage section. By clicking on it, you can select the “Memory card” option. If the button is inactive or missing, transfer is not possible using software.
⚠️ Attention: Applications transferred to the SD card may work slower than from the internal memory. It is better to leave critical services (messengers, banking applications) in internal storage.
The situation is similar for games. Heavy games often store cache files (folders Android/obb) in the internal memory. Some file managers allow you to move these folders manually, but this may cause the game to crash when updating. Be careful with manual modification of system paths.
☑️ Checking the ability to transfer the application
Setting up the camera to record directly to SD
In order not to move files manually in the future, you can set up your smartphone camera to automatically save new pictures and videos directly to the memory card. This will save the internal memory from quickly filling up.
Open the application Camera and click on the gear icon in the corner of the screen. In the menu that opens, find the “Storage location” or “Save to” item. Switch the toggle switch from “Phone” to “Memory Card”. Now all new media files will be recorded directly to the external drive.
Please note that when recording video in Super Slow-mo or 8K resolution, the system may force the use of internal memory due to recording speed requirements. In normal photo and video mode, 4K recording to SD works stably when using fast cards.
Automatic recording to a memory card is the best preventive measure against filling up the internal storage of a smartphone.
Using My Files Explorer
Built-in file manager My files ot Samsung is a powerful tool for data management. It allows you to perform bulk operations of copying, moving and compressing archives. The interface is intuitive and divided into categories.
To transfer scattered files, go to the “Internal storage” section. You can sort files by type (Documents, Downloads, Audio). Select the desired groups of files, click “Move” and specify the path on the SD card. This is convenient for organizing order in a folder Downloadthat is often cluttered.
You can also create backup copies of contacts or messages through this explorer, although it is better to use cloud services for this. The main advantage of a local manager is the speed of working with large amounts of data without the need for an Internet connection.
⚠️ Attention: The menu interface and item names may vary slightly depending on the shell version One UI. If you do not find the item in the specified location, use the search in the settings.
Frequently asked questions about data transfer (FAQ)
Can WhatsApp be transferred to a memory card?
