Transfer of data to SD-The map in Xiaomi smartphones is a pressing task for users who face a lack of internal memory. Even models with 128 GB and 256 GB over time filled with photos, videos, app cache and system updates. From storage formatting to limitations MIUI In this article, we'll look at all the ways, from standard system functions to hidden capabilities for power users.

It is important to understand that not all data can be transferred to the SD-For example, system applications and some user programs (especially those requiring high performance) remain in internal memory. 30-50% And if we take the right approach, we'll look at the official methods for MIUI 14/15, workarounds for older versions, as well as solving common errors such as "SD-card not found" or "Inadequate rights".

⚠️ Warning: Formatting as "internal storage" links the card to the device, and once removed, it will not be read on another gadget without re-formatting.

2. transfer of files (photos, videos, documents) to SD-map

The easiest way to free up internal memory is to transfer media files, which can be done in MIUI through both the built-in file manager and third-party applications, and let's look at both.

1. Open the Camera app.
2. Put it on the gear (⚙️) Or swipe left to open the settings.
