How to rename a folder to Android Xiaomi Redmi: the complete guide

Arranging files in a smartphone is key to fast digital operation and order. Many Xiaomi and Redmi device owners are faced with the need to change the standard name of the directory they created to better navigate the content. However, the standard MIUI or HyperOS shell interface does not always offer an obvious solution to this problem, by tying the renaming function into nested menus or requiring the use of third-party tools.

Unlike desktop computers, where right-click solves most problems, on a touch screen, the logic of file management is often different. Users can spend hours searching for the Rename button without knowing that it is hidden behind a long press or only available through a specific viewing mode. Understanding the structure of the Android file system helps not only give names to folders, but also competently build the entire storage architecture.

In this article, we will discuss all the available ways to change directory names, from standard tools to advanced methods for power users, you will learn why some system folders cannot be touched, what are the limitations of the file system and how to avoid errors that can lead to malfunctions in applications.

Staff file manager and its capabilities

Most Xiaomi users rely on the pre-installed Explorer app, which has a yellow folder icon, a powerful tool designed specifically for the MIUI shell, allowing them to perform basic operations with files without installing additional software, and this is where renaming is most often sought, as the interface seems to be the most friendly and understandable for beginners.

To change the folder name, you need to open the application and go to the Files or Categories section, where all directories are displayed. The standard procedure requires highlighting the object: you need to click on the folder icon and hold your finger for one to two seconds until it stands out in color and the bottom toolbar appears.

But there's an important caveat that not everyone knows about: Some firmware versions only allow renaming in list view mode, not in tiles mode. If you don't see the right option, try changing the view through the conductor's own settings. Also, it's worth considering that system folders labeled as protected or created by the operating system can be blocked to edit the name.

💡

If the rename button is inactive, check if the file inside the folder is open in the background – this can block access to directory attributes.

It is worth noting that Xiaomi’s regular Explorer sometimes works unstable with very long file names or names containing special characters. The system can automatically crop the name or replace inadmissible characters with underline. There are practically no restrictions for standard Latin and Cyrillic names, but it is better to avoid using reserved characters such as /, \,:, *,?, ", <, >, |.

Using Google Files to Manage Directories

If the built-in tools seem uncomfortable or don't work properly, Files by Google is a great alternative.This file manager is often pre-installed on Redmi smartphones, but even if it's not, it's free to download from the Google Play Store. The app is famous for its minimalist design and lack of advertising, making the file process enjoyable and fast.

The renaming process is more intuitive here. Once you open the app, find the folder you want in the Overview or Internal Memory section. As with the regular conductor, you need to press the object for a long time to highlight it. Once you select it, you will see an action bar at the top of the screen where you need to click on the icon from three vertical dots. In the dropdown list, select "Rename", type a new name and confirm the action with the OK button.

The advantage of Google Files is that it has a smart hint system and security, and it will alert you if the new folder name matches the one already in the directory, which will prevent confusion, and it can handle encoding better and rarely allow for "dry-colored" file names, which sometimes happens when you transfer data from other devices.

Without access to all files on the device, the app will not be able to see the folders you want to rename.If the list is empty, check the permission settings in Settings → Applications → Files and make sure that access to the storage is allowed.

Advanced Managers: Total Commander and Solid Explorer

For users who want maximum control over the file system, it is recommended to install specialized file managers such as Total Commander or Solid Explorer. These applications offer functionality close to desktop operating systems, including dual-panel mode, work with archives and access to hidden system partitions.

In Total Commander, renaming is even easier: just find a folder, click on it (or use ticking), and select the option “Rename/move” from the menu or using hotkeys if you have a physical keyboard connected. The feature of this application is the ability to batch renaming, when you can change the names of several folders at once according to a given template, which is extremely convenient when sorting large amounts of data.

Solid Explorer offers a modern interface with support for Material Design and easy navigation. Here, renaming is available through a long press and action menu. A unique feature is the ability to edit file attributes and folders, including access rights, which can be useful for advanced users working with root rights.

Third-party managers also provide access to transaction logs, and if the renaming failed, you can find the cause of the error in the application event log, especially when working with network storage or cloud services integrated into the file manager.

File system limitations and system folders

The Android file system, whether ext4 or newer F2FS, imposes certain restrictions on naming objects, and understanding these rules will help avoid errors and data loss, especially with reserved names and symbols that the system uses for its own markup.

There are a number of folders that are strongly discouraged from renaming, even if the file manager technically allows it, including system directories such as /Android, /data, /system. Changing their names can lead to a bootloop (cyclic reboot) or a complete failure of the smartphone, requiring a flashing device.

⚠️ Note: Attempting to rename the folder DCIM (where photos and videos are stored) can cause the camera to stop seeing the gallery and the Gallery app to stop displaying the images taken.

Although modern file systems support long titles (up to 255 characters), some applications may not properly display or process paths containing too many characters. The optimal folder name length is up to 30-40 characters, which ensures compatibility with most programs.

Special attention should be paid to encoding. Android file system defaults to UTF-8, which allows the use of Cyrillic and emoji in titles. However, if you plan to transfer files to older devices or computers with non-standard settings, it is better to use Latin to avoid display problems.

Work with SD-map and external storage

Renaming folders on an external microSD card has its own features related to access rights and the drive file system. Often memory cards are formatted in FAT32 or exFAT, which have stricter restrictions than the internal memory of the phone. For example, in FAT32, file and folder names cannot be longer than 255 characters, and some special characters cannot be used in them.

When working with SD-The security system Android (starting with version 6.0 and above) isolates the access of applications to external drives. When you try to rename a folder on the map through a third-party file manager, the system can request permission to access the card's root directory. You must click "Allow" and select the card's root folder in the window that opens.

If the memory card has been formatted as "Adoptable Storage," it's encrypted and linked to a particular device, and in this case, the renaming is standard, but you can't extract the card and read it on another device without formatting, which is an important point for those who plan to change media often.

Speed of working with files on SD-If the renaming process takes too long or hangs, this may indicate a slow write speed or wear. In such cases, it is recommended to check the status of the card using utilities such as: SD Insight.

Comparison of popular file managers

For the convenience of choosing a tool for working with files, we have prepared a comparative table of the main characteristics of popular file managers available on Xiaomi and Redmi.

As you can see from the table, regular tools are often inferior to specialized applications in flexibility, but they benefit from system integration. Total Commander remains the choice of professionals thanks to the support of plugins that allow you to work with FTP, LAN and cloud directly.

The choice of application also depends on the version of Android. 11, 12, 13, 14) file-access Android/data Only some file managers, such as Solid Explorer or X-plore, can circumvent these limitations by requesting special permissions through the system interface.

💡

For a normal renaming of folders, a regular Explorer or Google Files is enough, but for complex work with the file system, it is better to install Solid Explorer or Total Commander.

Frequent problems and ways to solve them

When renaming folders, users can encounter a variety of errors, the most common being "failed to rename" or "file busy," which means that some process or application is currently using files inside that folder, and the solution is simple: close all applications, especially those that may have opened files from that directory, and try again.

Another problem is that there's no renaming button, which often happens when you've allocated multiple objects at the same time, and the renaming function only becomes available when you've selected one folder, and if you accidentally hit adjacent files, unblock the selection and only click on the desired folder.

⚠️ Warning: If you rename an application data folder (like a game cache) the game stops running, don't panic. Just give the folder the original name. The path structure must remain unchanged for the software to work properly.

Sometimes it helps to reboot the device. If the file manager is “hanging” or does not see changes, a simple rebate of a Redmi smartphone can clear the cache of the conductor and restore normal operation, and it is worth checking for updates for the Explorer application itself in the GetApps store or Google Play store.

In rare cases, the problem may be file system corruption, and if the renaming doesn't work anywhere, you should check the disk for errors, and you can use your computer by connecting your phone to USB, or use the built-in diagnostics in the Recovery Recovery menu.
