Smartphone owners Samsung often face a lack of built-in storage, especially when actively shooting high-resolution videos or installing “heavy” applications. The internal memory fills up quickly, and the system begins to warn about lack of space, which leads to the device slowing down. The only effective solution in this situation is to use an external microSD format. memory card. Moving files to external media not only frees up precious gigabytes, but also speeds up the operating system. In this article, we will analyze in detail all the available methods for transferring information, from standard file manager tools to setting up a camera to save pictures directly to a flash drive. microSD format.
Moving files to external media not only frees up precious gigabytes, but also speeds up the operating system Android. In this article, we will analyze in detail all the available methods for transferring information, starting from standard file manager tools and ending with setting up a camera to save pictures directly to a flash drive.
The process of migrating data on devices Samsung Galaxy is maximally simplified thanks to the shell One UI, however, there are some nuances that must be taken into account. For example, not all applications support working with external storage, and some system files cannot be transferred at all. We will look at safe methods that guarantee the safety of your personal data.
Preparing a memory card and checking compatibility
Before you start transferring files, you need to make sure that your memory card is inserted correctly and is recognized by the system. In modern smartphones Samsung the tray is often combined, so it is important not to confuse the installation side of the SIM card and microSD. After physical installation, the device should make a characteristic sound or show a notification about connecting a new drive.
It is recommended to use speed class cards UHS-I or UHS-II with a capacity of 64 GB and higher. Slow drives can cause delays when launching applications or freezing of the interface when viewing the gallery. If you plan to store 4K video there, the minimum speed class should be V30.
⚠️ Attention: Before starting a large-scale data transfer, make sure that the battery charge is at least 30-40%. A sudden power outage while recording files can damage the file system of the memory card.
You can check the connection status through the settings. Go to Settings → Device maintenance → Memory. Here you will see the total amount of internal memory and the amount of available space on the external card. If the card is displayed as “Not connected,” try removing and reinserting it or checking for mechanical damage to the contacts.
Using the built-in file manager “My Files”
The most reliable and easiest way to move existing photos, videos and documents is to use standard application "My files". This tool is pre-installed on all smartphones Samsung and provides full access to the file system without the need to install third-party software.
To get started, open the application and select the section Internal memory. Find the folders that are taking up the most space. Usually this DCIM (photos and videos from the camera), Download (downloads from the browser) or Documents. Highlight the desired files with a long press, then click the “Move” or “Copy” button in the bottom menu.
☑️ Preparing to transfer files
After selecting the action, the system will prompt you to specify the target folder. Go to the Memory card section and create a new folder or select an existing one to save data. It is important to distinguish between the “Copy” and “Move” functions: in the first case, the data will remain both there and there, doubling the space; in the second, it will be deleted from the internal memory after a successful transfer.
| Data type | Recommended folder on SD | Possible problems |
|---|---|---|
| Photos and videos | /DCIM/Camera | Slow thumbnail in the gallery |
| Documents | /Documents | Applications may not see files |
| Music | /Music | Crashes in playlists |
| Downloads | /Download | No |
Setting up automatic saving of photos and videos to SD
In order not to transfer files manually each time, you can configure the application Camera to automatically save pictures directly to the memory card. This is especially true for owners of models without a microSD slot who use external drives via OTG, or for those who shoot a lot of video in 4K.
Open the Camera application and go to settings by clicking on the gear in the corner of the screen. Find the item Storage location (or “Save to”) and switch the toggle switch from “Device memory” to “Memory card”. From now on, all new pictures will be automatically recorded to external media.
What to do if the option to save to SD is inactive?
If the switch is inactive (gray), the memory card may not be formatted correctly or has too low a writing speed. Try formatting the card through your phone settings (Settings → Device maintenance → Memory → Memory card → Format). Please note that formatting will erase all data on the card!
It is worth noting that Burst Shot (burst mode) and 8K video recording may still be saved to internal memory due to high write speed requirements, which not all microSD cards can consistently provide. In such cases, the system will automatically select the fastest available drive.
Transferring applications and games to a memory card
In modern versions Android and shell One UI the ability to completely transfer applications to a memory card is limited by developers for the sake of security and performance. However, this feature is still available for some apps. Go to Settings → Applications, select the desired app and click “Memory”.
If the “Change” button is active, you can select the option to use “Memory card”. Once confirmed, the application and some of its data will be moved. The cache and critical system files will remain in the internal memory, which ensures stable operation of the smartphone smartphone.
⚠️ Attention: Do not try to transfer system applications or Google services (GMS) by forced methods. This can lead to unstable operation of the phone, endless reboots, or bricking of the device.
For games with a large cache size (for example, PUBG, Call of Duty), the OBB file mechanism is often used. Some games allow you to choose the path for saving additional data in their internal settings. If there is no such option, you will not be able to transfer the game using standard means, and it will take up space in the internal storage.
Use memory cards marked “A1” or “A2” (Application Performance Class). They are optimized for running applications and provide faster random data reading speeds than regular cards.
Formatting a memory card as part of the internal memory
There is a function that allows you to combine the internal memory and microSD card into a single space. This process is called formatting as internal storage. After this operation, the card is encrypted and tied to a specific device, so it will not be possible to read it on another phone or computer without reformatting.
To activate, go to Settings → Device maintenance → Memory, select your card and click “Storage Settings”. Select the "Format as internal memory" option. The system will warn you that all data on the card will be deleted, so make a backup copy in advance.
This method is ideal for budget models with a small amount of built-in memory (16-32 GB). It allows you to install more applications and games that do not physically fit into the factory volume. However, the speed may be reduced if the memory card is slower than the built-in module eUFS.
| Option | Portable storage | Internal storage |
|---|---|---|
| Access from PC | Yes (via adapter) | No (only via phone) |
| Application installation | Limited | Full |
| Security | Standard | Encryption is tied to device |
| Speed | Depends on the card | Maximum (hybrid) |
Solving problems when transferring data
Sometimes users encounter errors when copying or moving files. One common problem is the "File is too large" message. This occurs if the card is formatted with a file system FAT32that does not support files larger than 4 GB. The solution is formatting in exFAT.
Another problem is the “slow” operation of the gallery after transferring the photo. This happens because the system needs to re-index the media files. The process can take from a few minutes to an hour depending on the number of photos. During this time, the phone may become slightly warm.
The exFAT file system is the best choice for memory cards with a capacity of 64 GB and above, as it supports large files and is compatible with most modern devices.
If the memory card suddenly can no longer be detected or files become inaccessible, do not panic. Try rebooting your device. If this does not help, check the card on your computer using the utility chkdsk (for Windows) or Disk Utility (for macOS) to fix file system errors.
Is it possible to transfer WhatsApp to a memory card?
You cannot completely transfer the WhatsApp application to a memory card, as this will break the operation notifications. However, you can transfer media files (photos, videos) and chat backups. To do this, in WhatsApp settings, go to Data and storage → Media saving path and select the memory card. Old media files will have to be transferred manually through the file manager from the folder Android/media/com.whatsapp.
Why did the thumbnails disappear after transferring the photos?
This is a temporary phenomenon. After moving a large amount of photos, Android takes time to scan the new file location and update the media content database (.thumbnails). Leave the phone connected to Wi-Fi and charging for 30-60 minutes, the thumbnails should be restored.
Is it safe to store a single copy of a photo on a memory card?
MicroSD memory cards are less reliable than the built-in memory of a smartphone or cloud services. They are sensitive to static electricity, temperature changes and physical bending. Never Do not store important data only on a memory card without a backup copy in the cloud (Google Photos, Samsung Cloud) or on a computer.
