Owners of modern smartphones Samsung Galaxy often face a lack of built-in storage. Cameras are becoming more powerful, apps are taking up gigabytes, and the basic version of the device is quickly filling up. Fortunately, most models in the series A and some flagships support memory expansion using cards. microSD.
Proper distribution of files allows you to not only free up valuable space in the internal memory for system updates, but also speed up the operation of the device. In this article we will analyze all the available methods data transfer: from standard Android tools to using proprietary software Samsung Smart Switch.
The process does not require special technical skills, but it is important to follow the sequence of actions so as not to damage the files. We will look at the nuances of working with media files, documents, and even some applications that can be moved without losing functionality.
Preparing a memory card and smartphone
Before you start migrating data, you need to make sure the media is compatible. Smartphones Samsung usually support cards up to 1 TB, but for correct operation it is better to choose models with high write speeds (Class 10 or UHS-I/UHS-II). Insert the card into the slot until you hear a characteristic click.
After physical installation, the system will automatically recognize the new drive. You will be asked to choose how to use it: as portable storage or as part of internal memory. For most tasks, including storing photos and music, the optimal mode portable storage.
⚠️ Attention: If you choose to format the card as part of the internal memory, it will be encrypted and cannot be read on other devices or a computer without special access.
Make sure that you have sufficient battery power. Although the process is not energy-intensive, suddenly turning off the smartphone while recording files can damage them. Check the status of the card through the settings menu.
☑️ Check before transfer
Transferring photos and videos through the Gallery application
The most common scenario is moving media content. The built-in application Gallery from Samsung allows you to do this en masse, without resorting to third-party file managers. Open the application and go to the section with photos or videos.
Press your finger on one of the files to activate the selection mode. You can select individual pictures or click on the menu icon (three dots) and select option Select all. This is especially convenient when clearing the internal memory of old archives.
After selection, click on the button More or three dots in the lower right corner of the screen. In the menu that appears, select Move. The system will prompt you to select the target directory. Find your memory card in the list SD card and specify the folder, for example DCIM or Pictures.
When moving large amounts of video (more than 10 GB), it is better to do this in 2-3 GB portions to avoid interface freezes and recording errors.
The operation time directly depends on the amount of data and the speed of the memory card. Do not close the application or lock the screen until the process is complete. If you interrupt the transfer, some files may be broken or disappear from both locations.
Managing files through the My Files application
For more detailed work with documents, downloads and archives, it is better to use the system explorer My files. This tool gives full access to the directory structure of both internal memory and external storage.
Launch the application and select the partition Internal storage. Find folders that are taking up a lot of space. Often this is a folder Download (downloads from the browser) or messenger cache. Highlight the desired elements with a long press.
Click on the menu More and select Move or Copy. The difference between these actions is critical: moving deletes the original, freeing up space immediately, and copying creates a duplicate, which is useful for insuring important data.
| Data type | Recommended folder on SD | Can I move |
|---|---|---|
| Photos and videos | DCIM/Camera |
Yes, without restrictions |
| Music | Music |
Yes, completely |
| Documents | Documents |
Yes, completely |
| Application cache | System folders | No, requires root |
⚠️ Attention: Moving system folders or application configuration files may cause apps to malfunction. Transfer only user content.
After selecting the destination folder on the memory card, confirm the action. The file manager will show a progress bar. When finished, check if the files open in the new location before deleting them from the internal memory (if you used copy).
Setting up the camera to save to a memory card
To avoid manually transferring data in the future, you can set up your smartphone camera to automatically save new pictures and videos directly to the card microSD. This will prevent the internal storage from quickly filling up.
Open the application Camera and click on the gear icon in the upper left corner to enter settings. Scroll down the list of options to the Save locationsection. Switch the toggle switch to the active position.
Now all new media files will be recorded to external media. However, it is worth considering that the writing speed on cheap cards may be lower than that of internal memory. This may result in delays when shooting bursts or recording high-resolution video. 4K.
Why might the option be grayed out?
If the "Save Location" option is grayed out or missing, check whether the card is inserted correctly. Also, some shooting modes (for example, "Slow Motion" or "Professional Video") always save data to internal memory due to high bit rate requirements.
For viewing existing photos, this setting does not work retrospectively. Old pictures will remain in the internal memory and will have to be transferred using the methods described in the previous sections. Regularly check the free space on the card.
Transferring applications to a memory card
The ability to move applications to a memory card in modern versions of Android is limited by software developers. However, for some apps in Samsung Galaxy this function is available through the system settings.
Go to Settings → Applications. Select the app you want to move from the list. If the developer has allowed the transfer, you will see an active button Edit in the section Storage.
Click on it and select an option Memory card. The system will warn you that some application functions may become unavailable, and widgets may no longer work correctly. Confirm the action and wait until the process completes.
⚠️ Attention: When you delete an application or remove the memory card, the data of the moved app will be lost. Also, the launch speed of such applications may be noticeably slower.
Not all applications support this function. Social networks, instant messengers and system utilities are usually tightly tied to internal storage to ensure security and performance. In such cases, the button for changing storage will be inactive.
Moving applications is only advisable for games with a large cache size or rarely used utilities. It is better to leave critical apps in the internal memory.
Using Samsung Smart Switch for migration
The utility Samsung Smart Switch is designed primarily for transferring data from an old phone to a new one, but it also has storage management functions. This method is convenient if you want to make a full backup to the card before resetting the settings.
Launch the application Smart Switch on your device. Select option Backup. Specify SD memory cardas the target device. The application will prompt you to select the types of data to save: contacts, messages, call log, settings and media.
This method creates a special folder structure that is understandable only to the utility Smart Switch. To recover data, you will need this application again. This is a reliable archiving method, but is not suitable for everyday access to files through the gallery or player.
Use this method if you plan to sell your smartphone or perform a full factory reset. A backup copy on the memory card ensures that you can quickly return all data to its place after formatting.
Frequently asked questions and problem solving
Why does the smartphone not see the memory card after transferring data?
The card may have been removed incorrectly or the file system may be damaged. Try rebooting your device. If this does not help, go to Settings → Device maintenance → Storage and check the card status. Formatting may be required (data will be deleted).
Is it possible to combine the internal memory and card into one?
In modern One UI shells this feature (Adoptable Storage) is often hidden or disabled. Even if it is available, we do not recommend using it, as it reduces the overall speed of the system and binds the card to a specific phone.
What to do if the transfer is stuck at 99%?
Do not turn off the phone immediately. Wait 10-15 minutes. If progress does not move, the file may be damaged or the card has bad blocks. Try interrupting the process and transferring files in smaller groups.
Does a memory card affect the speed of the phone?
Yes, if active applications are stored on the card or if the system is constantly indexing thousands of small files. Use high-speed cards (U3, V30) to minimize the impact on performance.
How to safely remove a memory card?
Never remove the card while the phone is on. Always use the Settings → Device maintenance → Storage → Advanced → Remove memory card. This ensures that all write operations are completed.
