Introduction: Why it is important to transfer photos to the right place SD-map
Smartphone Xiaomi Mi 8, released in 2018, still remains popular among users thanks to the powerful βironβ and camera with dual module 12 MP. However, even 64/128 GB of internal memory over time fill up, especially if you are actively taking pictures in RAW or shooting video in 4K. Transfer photos to a microSD card is a logical solution, but there are nuances.
First, the Mi 8 supports cards up to 256 GB (officially up to 128 GB, but many users are successful in using more capacious ones), and second, file transfer is directly dependent on the format of the card: if it is formatted as an internal memory (Adoptable Storage), the system can block manual movement. Third, not all methods are equally reliable: for example, using third-party file managers sometimes leads to the loss of EXIF metadata (date, geolocation, shooting parameters).
In this article, we will analyze 5 proven methods of photo transfer, their pros and cons, and give recommendations for choosing a memory card for Xiaomi Mi 8. If you have encountered errors such as βI failed to move the fileβ or βMemory card is protected from writingβ, here you will find solutions.
1.Preparation: checking the memory card and phone settings
Before transferring photos, make sure your microSD card is compatible with the Mi 8 and is properly configured.
- π Check the class of the card: for a photo class is suitable 10 or UHS-I (U1/U3). For the video. 4K pick up U3 or V30.
- π± Make sure the card is inserted into the hybrid slot SIM (second-slot SIM-Mi 8 does not support simultaneous operation of two SIM microSD!
- βοΈ Go to Settings. β Memory and check if the card is identified. If it's not, retrieve it and paste it back in.
- π If the card is formatted as internal memory, the transfer of files can be blocked, in which case you will have to reformat it (the data will be deleted!).
Pay special attention to the file system of the card:
- π FAT32 β Compatible with all devices, but limits the size of a single file to 4GB (problematic for video).
- π ExFAT is the best option for the Mi 8, supports files up to 16 EB and works faster.
- π NTFS β Not recommended for Android, but it can cause errors.
β οΈ Note: If you remove the memory card while transferring files, it can damage both the photos and the file system of the card.
Method 2: Transfer through a standard MIUI file manager
The easiest method is to use the built-in file manager from Xiaomi, which does not require the installation of additional applications and saves the metadata of photos.
- Open the Files app (yellow folder icon).
- Go to Images or Albums (depending on the MIUI version).
- Select the photos you want with a long tap (a tick will appear). To highlight everyone, click on the three dots in the upper right corner β Highlight everything.
- Click More (three dots) β Move.
- In the window that opens, select SD-map β destination folder (e.g, DCIM/Camera).
- Confirm the transfer button Move here.
If the Move button is inactive, the reasons may be as follows:
- π« The memory card is formatted as internal (you need to reformat it into portable).
- π Write protection is enabled on the card (check the physical switch on the adapter).
- π΅ The file system of the card is damaged (try formatting it via PC).
Check the free space on the map | Turn off battery optimization for the Files app |Close all background apps (especially the gallery) |Make sure photos aren't open in other programs-->
The speed of transfer depends on the class of the card and the number of files. For example, moving 100 photos of 5 MB on the SanDisk Ultra A1 will take about 1-2 minutes, and on a cheap no-name card β up to 10 minutes.
Method 2: Using a PC (the most reliable method)
Transferring photos through your computer is the safest way, as it eliminates the risk of interruption due to battery discharge or MIUI failure.
- π» Computer with Windows/macOS/Linux.
- π Cable USB Type-C (original or certified).
- π Cardholder (if you want to transfer files directly to the card).
Step-by-step:
- Connect the Xiaomi Mi 8 to your PC via cable. On your phone, select File Transfer (MTP) mode.
- On your computer, open this computer (Windows) or Finder (macOS). Your phone will appear as a removable drive.
- Go to Internal Storage β DCIM β Camera (or Pictures if you have saved the photos there).
- Copy the necessary photos (Ctrl)+C) and insert them into the folder on SD-card (if card in the phone) or on the computer (if you use a card reader).
- Wait for the copy to be completed and safely remove the device.
Advantages of this method:
- β‘ Maximum speed (especially when used) USB 3.0 and card reader).
- π‘οΈ Minimum risk of data loss (you can back up your PC).
- π§ Ability to convert photos (for example, from the HEIC into JPEG) before transfer.

If you transfer a photo to a map via a PC, create a folder with an understandable name on it (for example, "Xiaomi_Mi8_Backup_2026"). This will make it easier to find files in the future.
Method 3: Transfer over cloud services (Google Photos, Mi Cloud)
If you don't have a cable or a card reader on hand, you can use cloud storage, which is convenient for backups, but has speed and free space limits.
Let's look at two options:
| Service | Free volume | Max. File size. | Loading speed | Preservation of EXIF |
|---|---|---|---|---|
| Google Photo | 15GB (total with Gmail) | up to 200MB (photo) | Depends on the Internet. | Yes. |

| Yandex Disc. | 10GB | 50GB | Quickly in Russia | Yes. |
| Dropbox | 2GB | 50GB | Medium | Yes. |
Instructions for Google Photos:
- Install an app from the Play Market.

- Select the original quality (so that the photo does not shrink).
- Wait until the download is complete.
- On the phone, open Google Photos, highlight the photo β Save to the device and select SD-map.
Cons of this method:
- β³ Long loading with slow internet.

5. Method 4: Third-party file managers (Solid Explorer, FX File)
If the standard MIUI manager doesn't like it, you can use third-party applications with advanced features.
- π Viewing hidden files.
- π Create ZIP-archives right on the map.
- π Transfer files in the background.
- π Sorting photos by date, size or type.
Recommended annexes:

β οΈ Note: Some managers (e.g., managers, ES Conductor) contain ads and may request unnecessary permissions. Before installing, check reviews and ratings in the Play Market.

The file managers are convenient for mass file transfer, but do not always save the date of photo creation. If this is critical, use the standard MIUI manager or PC.
6. Method 5: Automation with Tasker or MacroDroid
