And you wondered why, even after you cleaned up the cache on Xiaomi, the memory runs out in days, and video files are one of the main eaters of internal storage. SD-The card will not only free up gigabytes, but also speed up the system, especially on budget models of Redmi or the Redmi. POCO However, standard copying through Explorer often leads to errors: files do not play, disappear after restarting, or take up space both there and there.
In this article - 5 working methods for transferring video to SD-map MIUI 12-14, including bypassing system constraints, configuring the card as internal storage and solving typical problems, and also a format compatibility table and a unique life hack for owners of smartphones with a Hybrid slot (when you can use the card for a mobile device). SIM + SD compete for one nest).
If you've tried copying a video through the Gallery and you get a message saying, "Not enough space," don't rush to buy a new card. 90 percent of the time, the problem is with MIUI settings, not hardware constraints. Next, step-by-step instructions, tailored to the firmware.
Preparation: which SD-Choose a map for Xiaomi
Not every memory card is suitable for video storage on Xiaomi. UHS-I (U1 or U3) speed 10 MB/s. For video in resolution 4K or 8K (For example, with Xiaomi. 13 Ultra will be required UHS-II or V30/V60 โ Otherwise, there will be lags or file breaks when recording.
Here are the minimum requirements for different scenarios:
- ๐ฑ Full HD (1080p): Class 10 card or U1 (32GB)
- ๐ฅ 4K (2160p): UHS-I U3 or V30 (64GB)
- ๐ Frequent re-recording (for daskam, video recorders): UHS-II or A2 (speed up applications)
- ๐พ Archive Storage: Any card from SanDisk, Samsung EVO or Kingston Canvas

Attention: Transcend and Silicon Power cards in the low-end segment are often forged. Check them through the SD Insight app (showing real volume and speed class). If a 128 GB card is defined as 32 GB, it is a fake.
Before buying, make sure that your Xiaomi model supports memory expansion. For example, the POCO F5 and Redmi Note 12 Pro+ have a Hybrid slot (either a second SIM or SD), and the Xiaomi 13 Lite is a separate slot for the card.

Method 2: Standard Transfer through the "Conductor"
The easiest method is to use the built-in MIUI Explorer. It is suitable for videos shot on the smartphone itself, but may not work with downloaded files from the Internet (due to the scoped storage limitations in Android 11+).
Step-by-step:
- Open the Files app (the folder icon on the desktop).
- Go to Video or Internal Storage โ DCIM โ Camera.
- Select the files you need with a long tap, then click โMoreโ โ โCopyโ.
- Go back to the root of the vault, select SD-map external_sd).
- Create a folder (like Videos) and click โInsertโ.
โ ๏ธ
Note: If the video is not played in the Gallery after transfer, check the map format. MIUI only works correctly with FAT32 or exFAT. NTFS cards (often used on PCs) are not supported!
To avoid duplicate files, delete the originals from internal memory after copying.

Method 2: Adjustment SD-maps as internal storage
If you want to have videos (and other files) saved by default SD-It can be mounted as an internal memory, and this is a method that is suitable for MIUI 12-14, but has nuances:
- ๐ The card will be encrypted and will not be read on other devices.
- ๐ The speed of the system may decrease (SD-cards slower than internal memory).
- ๐ซ Not all apps support recording to a โmountedโ card (such as TikTok or Instagram).
Instructions:
- Put it in. SD-smartphone-card.
- Open the Settings โ Storage.
- Tap by name. SD-maps (e.g. SanDisk) 128GB).
- Select โConfigure as an internal storage.โ
- Follow the system prompts (formatting is required!).
- After the reboot, go to Settings โ Apps โ Rights โ Storage and allow applications to access the SD.
Now all new videos from the camera will be saved to the map automatically, to return the settings back:

Method 3: Transfer over PC (for large files)
If the video takes tens of gigabytes (like recording from an action camera), copying via a smartphone can take hours.
Algorithm of action:
- Connect your smartphone to your PC through USB-cable (preferably original).
- On your phone, select File Transfer (MTP) mode.
- On PC, open โThis Computerโ and the Xiaomi device will appear there.

5. Method 4: Automatic transfer using applications
If manual copying seems tedious, use specialized utilities that can transfer files on a schedule, sort by folder, and even compress video without losing quality.
Top.-3 apps:
| Annex | Functions | Cons | Reference |
|---|---|---|---|
| Files by Google | Autocleaning, transfer to SD, search for duplicates | Advertising, no 4K support | Google Play |
| X-Plore File Manager | Two-panel mode, FTP-server, root access | A complex interface for beginners | Google Play |
| MiXplorer | Cloud support, encryption, dark theme | Requires manual installation (not in the Play Market) | XDA Developers |
๐ Instructions for Files by Google:
- Install the application and give access to the storage.
- Go to the โCleanupโ section โ โFilesโ โ โVideoโ.
- Select files and click โMove toโ SD-mapยป.
- Confirm the action (the application will prompt you to delete the originals).

If the video is not played after the transfer, try to rename the file by removing special characters (for example, replace video #1.mp4 with video1.mp4). MIUI sometimes blocks files with "non-standard" names.
Method 5: Transfer over ADB (for power users)
If standard methods donโt work (for example, due to the scoped storage limitations of Android 13), you can use ADB (Android Debug Bridge), which requires a PC and basic command line knowledge, but is guaranteed to work even with system files.
Step-by-step:
- Install. ADB-PC drivers.
- Enable USB Debugging on Xiaomi (see Section 4).
- Connect your phone to your PC and open the command line (Win + R โ cmd).
๐น Advantages of the method:
- ๐ Bypassing restrictions MIUI file-access.

Note: Incorrect use of ADB can lead to data loss. Do not follow rm or format commands unless you are sure of their operation. For security, backup: adb backup -f backup.ab -apk -obb -shared -all
7. Solving Typical Mistakes When Transferring Video
Even after successful copying, videos may not play or disappear after a reboot. Here are the most common problems and solutions:
| Mistake. | Reason. | Decision |
|---|---|---|
| "File is not supported" | Video codecs are not compatible with MIUI | Install a VLC player or convert to MP4 (H.264) |
| Video is available but not displayed in the Gallery | File hidden or path not indexed | Move the file to DCIM/Camera Update the media base with the command: adb shell am broadcast -a android.intent.action.MEDIA_SCANNER_SCAN_FILE -d file:///storage/XXXX-XXXX/Videos/ |
| The โNot Enough Spaceโ Error When Copying | SD-map FAT32 (4GB limit per file) | Reformat to exFAT via PC (all data will be deleted!) |
| Video played with lags | Low speed reading of the map | Replace the card with UHS-I U3 or copy the video back to internal memory |
If the video takes up space on both the phone and the map after transferring, check the synchronization settings of the Mi Cloud:
Settings โ Xiaomi Account โ Mi Cloud โ Gallery โ Disable โAutosynchronizationโ๐ก
Before formatting SD-Always check if the card is used as internal storage, otherwise the data will be lost and the system may stop booting!
