You can move photos, videos, and other files to a microSD card on a compatible Android device. Moving an installed app is more limited: it works only when the device and app support it and the relevant setting appears. Before formatting or changing how a card is used, back it up—formatting erases its data.
Check whether your Android device supports a microSD card
First confirm that your exact phone or tablet has a microSD card slot. The presence of Android alone does not guarantee one: Samsung says microSD support varies by Galaxy model. Check the device maker’s guidance for the model’s maximum supported capacity and card requirements before buying or formatting a card. Samsung lists microSD capacity up to 2 GB, microSDHC up to 32 GB, and microSDXC over 32 GB up to 2 TB; those card-class limits do not guarantee that a particular device supports every card in the range. Samsung’s microSD and Galaxy guidance is model-sensitive.
Choose portable or internal storage
When Android detects a card, it may offer a choice of how to format it. The right option depends on whether you want a removable card for files or app storage tied to this device. Google’s setup labels include “Format” for portable storage and “Format another way” for internal storage; wording and menus can vary by device.
| Storage mode | What it is for | Can the card move between devices? | Can apps be installed on it? |
|---|---|---|---|
| Portable storage | Files such as photos and videos | Yes, according to Google | No, according to Google |
| Internal (adoptable) storage | Files and app installation on supported devices | No, according to Google | Yes, where the device supports it |
These behaviors are described in Google’s SD card setup guide. Samsung says its Android devices do not support Android’s adoptable-storage feature, so Galaxy users should not expect that option to appear.

Back up the card before formatting
Formatting permanently deletes the card’s data. Copy anything you want to keep to another location before formatting or changing storage mode. Google’s SD card instructions explain the setup and reformatting flows; Samsung’s formatting path for supported software is Settings > Battery and device care > Storage > SD card > More options > Format. Exact labels and paths vary by model and software version.
For a newly detected card, Android’s documented flow is to tap the SD card notification, choose the storage mode, and select whether to move content now or later. To change a card’s mode later, Google documents options under Settings > Storage > SD card and storage settings. If the menu differs, use the device maker’s instructions for your model rather than assuming the same path applies everywhere.

Move photos, videos, downloads, and other files
Moving files is separate from relocating an installed app. The following methods move selected files to a folder on the card.
With Files by Google
Google documents this workflow for Files by Google on Android 8.0 and later:
Rank #3
- High-Speed Performance: Featuring UHS-I bus interface, the DIGIERA microSD card delivers up to 100MB/s read and 40MB/s write speeds, making it perfect for transferring 4K UHD videos, RAW photos, and large files quickly. Based on internal testing, performance may be lower depending on host devices, interfaces, usage conditions, and other factors
- 128GB Ample Storage: With 128GB of storage space, the DIGIERA memory card holds approximately 24,000 high-resolution photos, 5+ hours of 4K UHD video, or extensive game files. Due to different capacity algorithms and partial capacity used for system files, management, and performance optimization, the available capacity may be less than the identified capacity
- Broad Multi-Device Compatibility: Equipped with SDXC technology and an included SD adapter, this mini SD card works with smartphones, tablets, laptops, cameras, drones, gaming consoles, security cameras, and more. Device support may vary—please check your device’s compatible card type and capacity before use

- Open Files by Google and find the file in Categories or Storage devices.
- Select the file or files, then tap More and choose Move to or Copy to.
- Select SD card, choose or create a destination folder, and complete the move or copy.
The app may also show a Move to SD Card card on its Clean tab when that option is available. See Google’s Files help for moving or copying files to an SD card.
With Samsung My Files
- Open My Files and select the file or files.
- Tap Move or Copy, then choose SD card.
- Open the destination folder and tap Move here or Copy here.
Samsung says files moved this way are managed through My Files. Encrypted music and other purchased content may not be movable to external storage. See Samsung’s Galaxy microSD instructions.

Move an installed app only if Android offers the option
App relocation is not a universal Android feature. On a Galaxy model that supports microSD, Samsung documents this path for an eligible app:
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →- Open Settings > Apps.
- Select the app, then tap Storage.
- If Change appears, tap it, choose SD card, and tap Move.
If Change is absent, Samsung says that app cannot be moved. The app developer may disallow SD-card storage, and Samsung gives preloaded apps as an example of apps that cannot be moved. Even when relocation is available, do not assume it moves every piece of app data or that the app will behave identically from removable storage. For other Android manufacturers, check the device maker’s support page and the app’s storage settings; the Galaxy path does not establish that another device has the same feature.
Quick Recap
Best Value
- 64GB Micro SD Card
- Class 10, UHS-1 performance allows fast and smooth continuous shooting, multiple frames per second and full HD video capture
- Fast performance minimizes photo and video transfer times to your computer
- Durable & ultra-reliable: magnet proof, shock proof, temperature proof, and waterproof
- Perfect for Android smartphones, tablets, digital cameras, game consoles, dash cameras, drones and surveillance systems, etc; It can use to store or back up high-res photos, videos, documents, music and more.
If the SD card or move option does not appear
- No card notification or SD card menu: Confirm the exact device has a microSD slot and that the card is seated correctly. Check the manufacturer’s model-specific compatibility and capacity requirements.
- No “Change” control for an app: The device or app is not exposing app relocation for that app. Use the card for files instead of relying on unsupported workarounds.
- Files app cannot find the card: Check the app’s storage-device list and the Android storage settings. Menu names differ by device and software version.
- Considering another storage mode: Back up the card first. Formatting to change modes erases its contents, and a card formatted as internal storage is not intended to move between devices.
