Owners smartphones Samsung Galaxy often face a lack of built-in storage, especially if they actively take photographs or record high-resolution videos. The built-in memory quickly fills up, the system begins to slow down, and notifications that space is running out appear more often. The solution to this problem is to use a memory card microSD, which can significantly expand the capabilities of the device without deleting important data.
Moving photos to an external drive is not just a way to free up gigabytes, but also guarantees the safety of your pictures in the event of a phone system failure. Modern models of the Galaxy A i M series support cards up to 1 TB, which turns the smartphone into a full-fledged archive. However, the transfer process has its own nuances, depending on the version of the shell One UI and the type of files.
In this article we will analyze in detail all the available methods: from automatically setting up the camera to manually moving existing galleries through the file manager. You will learn how to avoid common mistakes and why some files may not be transferred using standard means.
Preparing a memory card and checking compatibility
Before you begin transferring data, you need to make sure that your memory card is installed and formatted correctly. Smartphones Samsung require that the drive be formatted in the file system FAT32 or exFAT. If you inserted a new card, the system usually prompts you to format it immediately when you turn it on for the first time.
It is important to understand the difference between internal storage and external storage. The memory card is slower than the built-in flash memory, so launching applications from it can lead to slowdowns. However, for storing media files such as photos and videos, its speed is quite sufficient.
⚠️ Attention: Formatting a memory card completely deletes all data on it. If the card already contains important files, save them on your computer first.
You can check the card status in the device settings. Go to section Settings → Device maintenance → Memory. Here you will see the total volume and free space on both the internal disk and on the card SD. Make sure that the system sees the drive correctly and does not display read errors.
Use U3 or V30 speed class memory cards to record 4K video to avoid recording interruptions due to low recording speed.
Setting up automatic photo saving to an SD card
The most effective way to save internal memory is to configure the camera so that new pictures are immediately saved to the memory card. In the shell One UI this function is implemented very conveniently and does not require third-party applications. After enabling this option, you will no longer have to manually move fresh photos.
To activate the function, open the application Camera and click on the gear icon in the upper left corner. In the settings menu, find the item Save location. Switch the toggle switch to position SD card. Now all new photos and videos will be recorded to external storage by default.
- 📸 New pictures are automatically saved to external storage.
- 💾 The internal memory remains free for installing applications.
- ⚙️ The setting applies only to future files, old photos remain in place.
It is worth noting that some shooting modes, for example Slow Motion or shooting in ultra-high resolution, may ignore this setting and save data to internal memory due to write speed requirements. In such cases, the system notifies the user about a temporary storage switch.
Manual transfer of existing photos through the My Files application
If you have already accumulated a large gallery in the internal memory, you need to transfer it manually. The standard file manager My files (My Files) from Samsung is the best tool for this task. It allows you to safely move large amounts of data without the risk of losing information.
Launch the application My files and select a category Images or go to Internal storage → DCIM → Camera. Select the desired photos with a long press. You can select individual files or click on the menu (three dots) and select Allto move the entire folder.
Action: Click "Move" or "Copy" in the bottom menuAfter selecting the action, the system will prompt you to specify the target directory. Select Memory cardthen go to folder DCIM and create a new folder or select an existing one Camera. Confirm the operation by pressing the button Done or Move here.
☑️ File transfer algorithm
⚠️ Attention: Do not remove the memory card during the moving process. This may result in file corruption and the need to format the drive.
The process may take several minutes depending on the number and size of files. At this time, it is better not to run heavy applications so as not to load the processor and memory controller. Upon completion of the operation, check the presence of files on the card through the same file manager.
Moving data through a connection to a computer
To transfer very large amounts of data (for example, several tens of gigabytes), it is more convenient to use a computer. This method is often more stable and faster than wireless transmission or working directly with the phone interface.
Connect your smartphone to the PC using the original cable USB-C. A request for connection mode will appear on the phone screen. Select mode File transfer or MTP. On your computer, open Explorer, find your device and go to the folder Internal Storage.
| Option | Internal memory | Memory card (SD) |
|---|---|---|
| Speed reading | High (up to 500 MB/s) | Medium (up to 100 MB/s) |
| Reliability | High | Depends on quality cards |
| Access when the phone is turned off | No | Yes (via card reader) |
| Volume limit | Fixed | Up to 1 TB (depending on model) |
Copy the folder DCIM or other directories with photos from the internal drive to the computer, and then transfer them to the root or corresponding folder on the memory card, which will appear as a separate removable drive. Once complete, safely remove the device.
Why may the computer not see the phone?
Make sure the cable is working and supports data transfer, not just charging. Often the problem lies in a damaged cable or dirty USB port. Try a different port on your computer.
Problem solving: why photos don’t move
Sometimes users are faced with a situation where the system refuses to move files or displays an “Not enough space” error, although there are several gigabytes free on the memory card. This may be due to the characteristics of the file system or access rights.
One of the common reasons is formatting the card as internal memory (Adoptable Storage). In new versions Android i One UI this function is limited. If the card is encrypted for use only on this device, the transfer of some system folders may be blocked. In this case, try formatting the card as portable storage.
It is also worth checking for hidden files .nomedia. If this file is present in a folder on the memory card, the gallery may not display the photos, creating the illusion that the transfer was unsuccessful. Delete this file through the file manager, turning on the display of hidden items.
⚠️ Attention: The settings interface may vary depending on the Android version and Galaxy model. If you do not find the described items, check the latest information in the official user manual for your specific software version.
Another possible problem is damaged sectors on the memory card. Run an error check via Settings → Device maintenance → Memory → Advanced (three dots) → Memory card → Settings → Format (after saving the data). Sometimes simply reinserting the card helps.
If the transfer is interrupted on the same file, most likely this file is damaged or the memory card has bad sectors in this area.
Storage optimization and backup
After successfully transferring photos, it is recommended to set up backup. Even the presence of a memory card does not guarantee complete data security, since physical drives may fail. Using cloud services such as Google Photos or Samsung Cloudwill create an additional copy of your memories.
To optimize space, you can also use the function Cleaning in the device maintenance menu. It will find blurry photos, similar photos, and screenshots that you can delete. Regularly clearing the gallery application cache also helps maintain system performance.
- ☁️ Set up cloud synchronization for critical photos.
- 🗑️ Regularly delete duplicates and bad frames.
- 🔄 Make backup copies of your memory card to your computer every six months.
Remember that a memory card is a consumable item with its own service life. Do not store a single copy of unique photos on it for many years without duplicating it on other media.
For a long life of the memory card, avoid frequent complete overwriting of data. It is better to format it periodically, having previously saved the files, than to constantly delete and write new ones over the old ones.
Is it possible to transfer photos to a memory card if the phone does not see it?
No, the transfer is not possible until the system recognizes the drive. Try removing and reinserting the card, checking the contacts for cleanliness, or testing the card in another device. If the card is not detected anywhere, it may be faulty.
Will transferring photos to an SD card speed up your phone?
Yes, freeing up internal memory often speeds up the system, since Android requires free space for cache and temporary files. However, the photos themselves on the card may open a little slower than in the internal memory.
What to do if, after transferring, the photos disappeared from the Gallery?
Most likely, a .nomedia file has appeared in a new folder on the memory card, which hides media files from the gallery scanner. Find and delete this file through the My Files app, turning on show hidden items, then restart your phone.
Is it possible to transfer photos to a memory card on a Samsung Galaxy without an SD slot?
No, if your model (for example, the Galaxy S20 Ultra series or newer in some regions) does not have a microSD slot, physically transfer the files to the card inside the phone impossible. Use cloud services or connect the card via a USB-OTG adapter.
