Modern smartphones Samsung are equipped with excellent cameras capable of creating high-resolution images that take up a significant amount of built-in memory. Device owners are often faced with a situation where the internal storage is full and the system speed begins to drop. The solution to this problem is to use an external format card microSD, which allows you to store gigabytes of media content without loading the system partition.
The process of moving data is not always intuitive, especially after updating the interface One UI, where some menu items have been changed or hidden. Users need to figure out not only how to save new pictures directly to the card, but also how to safely move an already accumulated archive of photos from internal memory. Errors when working with the file system can lead to data loss or damage to image files.
In this detailed guide, we will look at all available methods: from standard application settings Camera to using advanced features of the file manager My Files. You will learn how to avoid common mistakes when removing media and what nuances exist when working with different versions of the operating system Android.
Preparing a memory card and checking compatibility
Before you begin transferring files, it is critical to make sure that your memory card is correctly installed and recognized by the system. Smartphones Samsung support cards of various speed classes, however, to record video in high definition, media with a marking of at least UHS-I or UHS-IIis required. Slow cards may cause delays in shooting or the inability to save the file when the image is taken.
Once the card is physically inserted into the slot (or hybrid tray), you must format it. This action will delete all existing data on the media, so copy important information to your computer in advance. Formatting creates the correct file structure that the file system understands Androidand prevents future read errors.
⚠️ Attention: If the system prompts you to select the card operating mode as “Portable storage” or “Internal memory”, select the first option. Internal memory mode encrypts the card for a specific device, and you will not be able to read it on another phone or computer without a complex decryption procedure.
To format, go to section Settings → Device maintenance → Storage. Here you will see a list of available drives. Click on the name of your memory card, then select Format. The system will warn you about data loss - confirm the action. After the procedure is completed, a message about the successful connection of the drive will appear in the notification shade.
Use an adapter for memory cards to check the functionality of the card on the computer before installing it in the phone. This will help identify bad sectors that could lead to the loss of photos in the future.
Setting up automatic saving of new pictures
The most effective way to free up space is to configure the application Camera so that all new photos and videos are saved directly to the memory card. This eliminates the need to manually move files after each photo shoot. This function is available in the standard application from Samsung and works stably on most models of the series Galaxy A and Galaxy S.
Open the camera application and go to the settings menu by clicking on the gear icon in the upper left corner of the screen. In the list of parameters that opens, find the item responsible for the storage location. In different firmware versions it may be called differently: “Storage location”, “Save to” or “Memory”. Change the value from “Internal memory” to Memory card.
After activating this option, all subsequent pictures, including series in mode Burst Shot and video in resolution 4K, will be recorded on external media. Please note that some specific modes, such as Professional Video or Video Recording RAW on certain models, may still require internal memory due to high data write speeds.
| Option | Internal Memory | Memory Card |
|---|---|---|
| Write speed | High (UFS 3.1/4.0) | Depends on the card class |
| Reliability | High | Average (risk damage) |
| Access from PC | Only via cable/MTP | Via card reader directly |
| Volume limit | Fixed | Up to 1 TB (depending on the model) |
Manually transferring existing photos via “My Files”
If you have already accumulated a large archive of pictures in the internal memory, you need to move them manually. For this purpose, smartphones Samsung are pre-installed with a powerful file manager called My files (My Files). It allows you to perform operations of copying, moving and deleting data between different storage sections.
Launch the application My files and select the section Internal memory. Find the folder DCIM, and inside it - the folder Camera. This is where all photos and videos taken with the camera are stored by default. Select the files you need: you can select individual pictures with a long press or click on the three dots in the corner of the screen and select Select all to move in bulk.
After selection files, click the button Move or Copy in the bottom menu. The Move option will remove the originals from the internal memory after pasting, freeing up space, while the Copy option will create a duplicate. Go to section Memory card, open the destination folder (you can create a new one, for example, Archive_Photos) and click Done or Insert here.
☑️ Safe transfer algorithm
⚠️ Attention: When moving a large amount of data (more than 10 GB), do not lock the smartphone screen or minimize the My Files application. Interrupting the process may result in files being damaged or disappearing from both storage locations.
Working with folders and organizing the structure on the media
Chaotic storage of thousands of photos on a memory card makes it difficult to find the right pictures and slows down the gallery when indexing media files. It is recommended to create a logical folder structure immediately upon migration. For example, group photos by year, month or event: 2026/Vacation_Sea, 2026/Birthday.
In the file manager My Files the creation of new folders is carried out through the menu of additional options (three vertical points). Select item Create a folder, enter the name in Latin or Cyrillic and confirm the action. Latin names are preferable, as they guarantee compatibility when connecting the card to car radios, TVs or older versions. They store gallery thumbnails, which can take up gigabytes of space. When transferring main photos, this cached data can be safely deleted through the storage settings so as not to transfer garbage to a new card. Windows.
It is also worth paying attention to hidden system folders, such as .thumbnails. They store gallery thumbnails, which can take up gigabytes of space. When transferring master photos, this cached data can be safely deleted through the storage settings, so as not to transfer garbage to the new card.
Hidden system files
When you connect the card to your PC, you may see folders with names like Android, LOST.DIR. Do not delete them manually from your computer, as this may disrupt the operation of applications on your smartphone that expect these directories to exist.
Solving access problems and recording errors
Sometimes users are faced with a situation where the phone sees the card, but refuses to write new photos to it or move old ones. A common cause is the media file system. Large capacity cards (more than 32 GB) are usually formatted in exFAT, which is supported Android. If the card has the format NTFS, the smartphone will only be able to read data, but not write it without special drivers or root access.
Another common problem is physical wear of the memory card. Flash memory has a limited resource of rewrite cycles. If you notice that files are saved with errors, become “broken,” or the transfer process freezes in one place, this is a sure sign that the media resource is exhausted. In this case, you need to replace the card with a new one.
Also check the application permission settings. Go to Settings → Applications, find “Camera” or “My Files”, go to the Permissions section and make sure that access to the storage is allowed. After security updates Android some permissions may be reset.
If the memory card is defined as “Damaged” or requires permanent formatting, it is most likely damaged. Attempts to revive such a storage device for important information are rarely successful - it is better to replace it immediately.
Safe removal and backup
Never remove the memory card from a working smartphone without first shutting it down. An abrupt eject could result in the loss of the file allocation table, rendering all information on the media inaccessible. Always use the safe removal feature, even if the phone turns off automatically when you open the tray (on some models).
To properly turn off, go to Settings → Device maintenance → Storage, select your card and press the Disable or Ejectbutton. Wait for a notification to appear indicating that the card can be safely removed. Only after this can you open the SIM card tray.
Remember that a memory card is a less reliable medium compared to the phone's internal chip. It is sensitive to temperature changes, moisture and static electricity. Regularly back up important photos to cloud services (for example, Google Photos or OneDrive) or to your computer's hard drive.
⚠️ Attention: The menu interface and item names may vary slightly depending on the version of the One shell UI (3.0, 4.0, 5.0, 6.0) and device models. If you do not find the described item, use the search in the settings (magnifying glass icon at the top of the settings screen).
Frequently asked questions (FAQ)
Can I transfer installed applications to a memory card on Samsung?
In modern versions Android and shell One UI the ability to transfer applications to a memory card is officially blocked by the developers to ensure system stability. Some applications only allow you to transfer their cache data (media files), but the executable file itself remains in the internal memory.
Why does the gallery show blank screens after transferring photos?
The Gallery application takes time to scan the new file location and build an index database. This is especially noticeable when transferring thousands of photos. Leave the phone connected to the charger and do not use it actively for 15-20 minutes to complete indexing.
What is the maximum memory card size that my Samsung supports?
Most modern smartphones Samsung support cards up to 1 TB. Older models (pre-2018) may be limited to 256GB or 512GB. The exact information can be found in the specifications of your model on the official website or in the user manual.
Will the photos disappear if I remove the card and insert it into another phone?
No, if you used Portable Storage mode (default), your photos will be available on any other device with a microSD slot or through a card reader on your computer. They are stored in the standard DCIM folder, which is read by all operating systems.
