SD Card Auto-formatting Tool (Windows & Linux)

Download a powerful tool that allows you to convert external MicroSD card of your Xiaomi phone to be an internal storage. It means you can use your SD Card just as your phone internal storage. You can move any installed apps to that storage then.

The tool is compatible to run on a Windows computer or a Linux machine. It is a very simple command-line tool that works.

Most Android users believe that root is needed to move the apps to their SD card. That is not truly wrong! Rooted Android phones allows its users to do almost anything since they have the root access.

However, rooting mechanism are still an impossible task for some users. On top of that, Xiaomi has applied a number of security protections to prevent malicious hackers getting access on MIUI devices. Anti-rollback (ARB) and Locked Bootloader are the good examples. Hence, the rooting procedure is not as simple as it was in two or three years ago.

This simple tool cuts the long way to achieve the same goal: using external SD card as an external one and moving installed apps on it. Thus, it can reduce the usage quota of the internal storage.

The main trade off is the need of fast SD Card. It is pricey compared to the slow one but it delivers promised read-and-write speed.

The tool is created by Tomhenson, a Super Moderator at MIUI global forum. All the thanks and credits go to him.

      1. I found it from somewhere else. The size was 14.8 Mb and it worked for me. I was able to partition the SD and then move the apps with Activity launcher.

          RAR file is either corrupt or requires a password. In either case, it is useless. This guide needs to be updated with a valid download link and/or the password to access the RAR file, otherwise, the guide is meaningless.
