How to transfer data to a memory card in a Xiaomi phone: all ways and life hacks

Filling up the internal memory of a smartphone is a problem that every second Xiaomi owner faces: high-resolution photos, heavy messengers, game cache and system updates eat gigabytes in a matter of months. The solution seems obvious: transfer data to a memory card. But how do you do it right, so as not to lose files, not to slow down the phone and not to face MIUI errors?

In this article, we will analyze all the current methods of transferring – from manually moving files to automatically saving new data on the Internet. SD. We will pay special attention to the nuances of working with memory cards in Xiaomi: why some applications can not be ported, how to avoid the error "Not enough space" when installing updates, and what to do if the phone does not see the card after formatting. 10 Xiaomi 14 Ultra on base MIUI 12/13/14.

We will warn you right away that not all data can be transferred to SD-For example, system applications and some games (especially those with anti-piracy protection) will remain in internal memory, but photos, videos, music, documents and even cache of some programs can be moved quite realistically.

1. Memory card preparation: formatting and file system selection

Before transferring data, you need to prepare correctly SD-A mistake at this point can cause the phone to either fail to see the drive or to run extremely slowly:

Step 1. Check card compatibility. Xiaomi officially supports microSD cards up to 2TB, but:

• 🔹 For models up to Redmi Note 9 (2020) the maximum volume is 512 GB.
• 🔹 Maps. SDHC (up to 32 GB and SDXC (64 GB) works, but SDXC Requires formatting in exFAT.
• 🔹 Cheap no-name cards are often forged – check the read/write speed (minimum 10MB/s for Class 10).

Step 2: Formatting: If the card is new or has been used in another device, it should be formatted directly on the phone.

1. Insert the card into the slot (some Xiaomi models require you to turn off the phone).
2. Go to Settings → Memory → Memory Map.
3. Click Format → As internal memory (if you want to port applications) or as a portable device (file only).

⚠️ Warning: Formatting as internal memory will make the card tethered to the phone, and once removed, it will not be read on a PC without further manipulation!

The file system is automatically selected, but if you format a card on a PC:

• 📁 For cards up to 32GB — FAT32 (Maximum file size: 4 GB).
• 📁 For cards from 64 GB - exFAT (supports files more than 4 GB).

💡

If the phone doesn't see the card after formatting, try formatting it into NTFS on your PC, and then repeat the procedure on your phone, which sometimes helps with file system conflicts.

2. Manual movement of files: photos, videos, music

The easiest way to free up space is to manually transfer media files, which doesn't require root rights and works on all versions of MIUI. Here's how to do it:

Method 1. Through "Conductor":

1. Open the Files app (folder icon).
2. Go to Images, Videos or Audio.
3. Select files (long press → ticks) → More → Move.
4. In the list of locations, select Memory Map and Destination folder (e.g. DCIM/Camera).

Method 2. Through the "Gallery" (for photo/video only):

1. Open the gallery, select the album.
2. Press Control. → Move it.
3. Point the folder to SD-map (if not, create: Create a folder).

One important thing to note is that when you move, don't copy, but move the files, otherwise they will remain in the internal memory, taking up space, to check that the files have moved:

1. Open the Settings → Memory.
2. Compare the place you occupy before and after the transfer.

⚠️ Note: Don’t move your Android folder manually, as this can break some apps. There’s a separate way for it (see section 4).

Select files in "Gallery" or "Conductor"

Use the “Move” option, not “Copy”

Check the vacant space in "Settings → Memory"

Create separate folders for photos, videos and music on SD-->

3. Automatically save new files to a memory card

To avoid manually transferring files every time, set up autosave to SD-This is true for photos, videos, screenshots and browser downloads.

For the camera:

1. Open the Camera app.
2. Press on. ⚙️ Settings → Preservation site.
3. Select a Memory Card and specify a folder (e.g. DCIM/Camera).

For downloads from the browser (Mi Browser or Chrome):

1. In Mi Browser: ⋮ → Settings → Downloads. → Preservation site → Memory map.
2. Chrome: ⋮ → Downloads. → Download folder → Memory map/Download.

For screenshots:

1. Go to Settings → Additional → Screenshots.
2. Select a Retention Site → Memory map.

After these settings, all new files will be saved immediately to the SD, saving internal memory. But remember: the write speed to the card is lower than to internal memory. If you shoot video in 4K or 8K, you may be lagging, in which case you better leave the save to the internal drive and transfer the files later.

4. Transfer of applications to a memory card: limitations and workarounds

Transferring applications to SD-Xiaomi's map is getting more complicated. MIUI 12, the function Move to SD App settings are often missing or blocked, due to Google’s policies and Android 10 restrictions.+. However, there are several working ways.

Method 2. With ADB (for advanced users):

This method requires connecting your phone to your PC and using Android Debug Bridge, and it works even if there is no port option in the settings.

1. Turn on Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Activate USB Debugging in Settings → Additional → For developers.
3. Connect your phone to your PC, open Command Prompt and type: Adb shell pm set-install-location 2 This will force the system to install new applications on the SD by default.

Limitations:

• 🚫 Not all apps support portability (especially system and secure games).
• 🚫 After the transfer, the application may run slower (depending on the class). SD-map).
• 🚫 Widgets of migrated applications can disappear from the main screen.

⚠️ Note: If the app stops working after the transfer, return it to internal memory. Some programs (such as WhatsApp or bank clients) block the work of the app. SD for security reasons.

5.Cache and application data transfer (without root)

Even if the app itself cannot be migrated to SD, sometimes you can move its cache and user data, and this is true for instant messengers (Telegram, Viber), social networks and games.

For messengers:

1. Open the application settings (e.g. Telegram → Settings → Data and memory).
2. Find the option of the Download Folder or the Media Saving Location.
3. Show the way. SD-map (e.g., map, /storage/XXXX-XXXX/Telegram).

For games:

Some games (such as Genshin Impact or Call of Duty Mobile) allow you to transfer cache:

1. Start the game → Settings → Additional → Move the data.
2. If there is no option, try clearing the cache (Settings) → Annexes → Game. → Warehouse → Clear the cache) and reload the data by selecting SD-map.

For Google Maps (offline maps):

⚠️ Warning: Cache transfer to a slow card (Class 4 or Class 6) can lead to brakes in games or a long load of media in messengers — UHS-I (U1 or U3).

💡

Transferring the app cache is one of the most effective ways to free up internal memory, but it doesn't work for all programs. Always check the settings of a particular application!

Errors when working with a memory card and their solution

When transferring data to SD-Xiaomi users often encounter errors. Let's look at the most common and how to fix them.

Error 1: "Memory card damaged"
