A full internal memory smartphone is a problem that every second owner of Xiaomi faces. Even models with 128 GB and 256 GB of memory quickly clog up high-resolution photos, 4K video, app cache and system updates. A microSD card seems like an obvious solution, but not everyone knows how to use it correctly. In this article, we will discuss all the working ways to transfer data to Xiaomi (including Redmi and POCO), given the limitations of MIUI and the peculiarities of working with applications.
It's important to understand that just copying files to a map is not enough, you need to configure the system so that new data is stored there by default, and the old ones do not take up space on the internal drive. We will look at both manual methods (via Explorer and PC) and automatic methods (camera settings, file downloads). SD-Map โ a feature that is not officially available in the latest versions MIUI, but has a workaround.
This article is relevant for Xiaomi smartphones on MIUI 12-14 (including HyperOS) and Android 10-14. If your model is older than 2018, some points may differ - check the availability of the described menus in the settings.
1.Preparation: Which Memory Card to Choose for Xiaomi
Before you transfer data, make sure your memory card is compatible with your phone. Xiaomi supports microSD up to 2 TB (theoretically), but in practice it is better to choose cards up to 512 GB from proven brands: SanDisk Ultra, Samsung EVO or Kingston Canvas. Speed class should be at least UHS-I (U1) for photos and U3 for 4K video.
Pay attention to the format of the map:
- ๐ฑ FAT32 โ Suitable for files up to 4GB (photos, music) and does not support files over 4GB (e.g. high-resolution video).
- ๐ฅ๏ธ ExFAT is the best choice for Xiaomi, supports files of any size and works faster. FAT32.
- โ ๏ธ NTFS โ Many Xiaomi smartphones do not work correctly with this format.
If the card is new, the phone will prompt you to format it when you first connect. Always agree - this guarantees compatibility with MIUI. If the card has already been used, format it manually through the phone's settings: Settings โ Storage โ Memory Map โ Format.

5. Method 4: Transfer data over PC (a reliable method for large volumes)
If you need to move tens of gigabytes of data (like a video collection or backup), it's more convenient to use a computer. It's faster and safer than moving through a phone.
Steps for Windows:
- Connect Xiaomi to your PC via USB-cable (use the original cable for a stable connection).
- On your phone, select File Transfer (MTP) mode in the connection notification.
- Open This PC โ the phone will appear as a removable drive (e.g. Xiaomi Redmi Note 12).
- Copy files from internal memory (Internal drive) to memory card (SD-map).
Steps for the Mac:
- Install Android File Transfer (official software from Google).
- Connect your phone and allow access to files.
- Drag files from the Internal Storage folder to the SD Card.

Instructions for Mi Cloud (composed with Xiaomi Cloud):
- Open your Settings โ Xiaomi Account โ Mi Cloud.
- Enable synchronization for Gallery, Contacts and other data.

- โ๏ธ Yandex Disk or Mail.ru Cloud: convenient for documents and archives.
The downside is that it depends on the speed of the Internet, and 10 GB of photos will require a stable connection and 1-2 hours of time, but it is the most secure way, since data is duplicated in the cloud.
