How to transfer WhatsApp to Xiaomi flash drive: the complete guide

Modern Xiaomi, Redmi and POCO smartphones are equipped with huge screens and powerful cameras, but even 256 GB of internal memory can run out unexpectedly quickly. The main “eater” of free space is WhatsApp, which for years accumulates gigabytes of photos, videos and voice messages. Owners of memory card-enabled devices often wonder: can you free internal storage by moving the history of correspondence to an external drive?

Unfortunately, the answer is not as clear as we would like. In older versions of Android (before version 10), this feature worked natively, allowing a couple of clicks to change the way data is stored. However, with the release of Android 11 and the implementation of the Scoped Storage policy, Google limited direct access to the file system, which made it difficult for users of MIUI and HyperOS. Now the standard menu means to move the database will not work.

However, there is a solution, and it requires a little more attention, but allows you to manage memory efficiently. In this article, we will discuss working methods for current firmware versions, look at manually moving files through the file manager, and discuss the nuances of working with backups. You will learn how to safely transfer media files and database without losing any important messages in the process.

Why WhatsApp is taking up so much space on Xiaomi

Before you start porting, it's important to understand the storage structure. Messenger doesn't just store text, it caches every image you send and receive, even if you've already deleted it from chat. The default backup system works with internal memory, creating heavy archives that take up space even after clearing the dialogs.

On Xiaomi devices, the situation is aggravated by aggressive optimization of background processes. The application can create duplicate previews or temporary files that are not deleted automatically. WhatsApp/Media maybe grow up 20-30 GB, which is critical for models with 64 GB of internal memory.

The main amount of memory is not text messages, but media files (video and photos) and their automatic backups created by the system.

It's also worth considering that the format of the msgstore.db database is growing all the time, and each new message adds weight to the archive, and if you're in dozens of active groups, it can be as large as a few gigabytes, making it impossible to store it on an internal drive when there's not enough space.

Android 11, 12, 13 and later

Since the eleventh version of the operating system, Google has changed the rules for applications to access files, and now Scoped Storage prohibits applications, including file managers, from arbitrarily moving folders of other programs, for security reasons, but for users accustomed to the freedom of file systems of the past, this has become a serious obstacle.

In earlier versions MIUI You can just go to WhatsApp settings and select SD-Now this menu item is either hidden or not functioning correctly on new Xiaomi smartphones.Trying to manually move the WhatsApp folder from the root of internal memory to the root of the flash drive often leads to synchronization errors.

⚠️ Warning: Attempt to force WhatsApp system files to move to a USB flash drive without following the correct folder structure of Android 11+ This will cause the messenger to stop seeing your chats and require re-registration.

In addition, the speed of the memory card plays a key role: If you use a cheap microSD card class 10 or lower, the interface of the messenger can become noticeably slower, and downloading media files will take longer. Internal memory of Xiaomi smartphones (UFS 2.1 or 3.1) is much faster than most memory cards.

Preparation of memory card and file system

For successful data transfer, you need to properly prepare an external drive. Not all memory cards are suitable for working with instant messengers in the read/write mode. It is recommended to use microSDHC or microSDXC cards with a speed class at least below UHS-I U3.

Before starting any operations, be sure to back up important data on your computer. The file transfer process, although it seems simple, carries the risk of data loss if the file system is accidentally interrupted or mistaken.

In smartphones Xiaomi there are two modes of operation with SD-We have to use the card to use Portable Storage and Internal Storage, and we have to use Portable Storage mode to use the card, and Internal mode encrypts the card for the device, so you can't read it on your computer or other phone if it breaks down.

Manual Transfer Method through File Manager

The most reliable way to migrate data on modern versions of Android is to manually copy files. For this, you will need a built-in Explorer app or a third-party file manager with extended rights, such as Total Commander or Files by Google.

First, you have to find the original data folder. The newer versions of Android have changed the path to that folder. Whereas before everything was at the root, now the database and media are often on the path of Android/media/com.whatsapp/WhatsApp or Android/data/com.whatsapp. The exact path depends on the version of the messenger and the MIUI firmware.

Once you find the WhatsApp folder, copy it (don't cut it out right away!) to your computer or to a temporary folder if you don't have enough memory. Then plug in the memory card. SD-card due to access rights, try using the computer as an intermediary or use the function "Access to system files" in the Explorer settings.

💡

Use System Folder Access (SAF) Explorer to get write rights to secure Android 11+ directories. Standard MIUI Explorer may not have such default rights.

Once you copy the folder onto a flash drive, the structure must be saved in its entirety. If you only transfer media files, create a WhatsApp/Media folder on the flash drive and put the content there. However, to make the database work, the path must be the same as the application expects to see when reinstalling.

Configuring ways to save media files

Although the chat database is difficult to migrate because of the encryption and binding to the UID of the application, media files (photos, videos, documents) can be redirected. WhatsApp itself has settings, but they do not always work correctly on Xiaomi. A more reliable method is to create a symbolic link, but this requires Root rights.

Without root rights, you can use Autoboot. Go to Settings → Chats → Chat Backup. Here you can set the save rate to Google Drive, freeing up local space. However, to save new media immediately to the map, use third-party automating apps that monitor the inbox and move new files to the SD.

The alternative for Xiaomi owners is to use the “Second Space” function or app cloning, but this does not solve the problem of space shortage, but only fragments it. The most effective is the regular manual transfer of old archives of dialogues to a USB drive via a computer.

WhatsApp Restores After the Move

If you decide to move the Databases folder to free up space or when reinstalling the system, the recovery process requires accuracy. Once you install WhatsApp on your phone (or after you reset), do not open the application immediately. First copy your saved WhatsApp folder from the USB drive to the appropriate internal memory directory.

It's important to keep a hierarchy: if the file was in Android/media... that's where it needs to be returned. If you put it in the root, the messenger may not find the backup. Once you copy, launch WhatsApp, confirm the phone number, and wait for the suggestion to restore the story from the local copy.

⚠️ Note: The backup file name must be msgstore.db.cryptXX, where XX — Do not rename files, otherwise recovery will not be possible.

In some cases, especially on HyperOS, the system can block WhatsApp from accessing newly copied files. If recovery does not begin, try giving the application all permissions to access files in the App System Settings → WhatsApp → Permissions and restart the device.

Alternative solutions to save memory

If you find the file tinkering too difficult or risky, there are simpler ways to free up space, and the most effective way to do this is to use the Storage Management feature inside WhatsApp itself, which allows you to find and delete the largest files and chat rooms that take up the most space.

Cloud solutions are also worth considering: Services like Google Photos or Mi Cloud can automatically download media from WhatsApp, after which they can be safely removed from the device. Xiaomi smartphones have a “Cleanup” feature that often finds duplicates and old messenger files.

Another option is to use WhatsApp Web on a computer or tablet to view an old story by deleting it from your phone, which allows you to keep only current correspondence on your smartphone, and store the archive in the cloud or on your PC.

Regular cleaning through WhatsApp’s built-in tools is more effective and safer than manually moving database system files.
