Xiaomi and Redmi smartphone owners often face a situation where the device begins to warn about space shortages. However, most users do not know the exact location of system folders and application cache. Understanding the physical and logical structure of the storage is necessary for competent file management, this avoids the accidental deletion of important data or system errors.
In Android, which runs the MIUI shell, internal memory is a complex file structure that is hidden from the eyes of the average user in standard viewing mode, requires special tools or a transition to developer mode, and we will discuss how to safely access root directories.
Knowing the exact path to system partitions will help you manually clean up debris that automatic cleaners ignore, which is especially true for low-volume models. Let's take a closer look at the storage architecture and how to work with it.
Structure of Android file system on Xiaomi
The logical organization of data in Redmi smartphones is based on Linux standards. Unlike Windows computers, there are no usual disk letters (C, D, E). All information is stored in a single directory tree starting with the root /. User access is usually limited to the /storage/emulated/0 folder, which is displayed as "Internal Storage".
The system files that are required for the CPU and operating system to work are in protected partitions, and they are hidden from modification without obtaining superuser rights (root), this is done for security: accidental change of the configuration file can lead to a "brick" of the device. The path to user data is written rigidly in the system variables.
Itβs important to understand the difference between internal memory and an SD card. While they may look similar in the interface, they are physically different chips. Internal memory (eMMC or UFS) is soldered on the motherboard and runs much faster than external drives.
The /storage/emulated/0 path is the primary gateway for all user applications and files in modern versions of Android. This is where photos, downloads and documents are saved by default.
β οΈ Note: Do not try to delete files in folders Android/data or Android/obb without understanding their purpose, and this can cause games and programs to malfunction.
Why is the path called emulated?
How to find a way to memory through a guide
The easiest way to see file locations is to use a standard file manager, which is called Explorer (or File Manager) on Xiaomi smartphones. The app icon is usually yellow with a folder image, and you run it and you get to the root of the user partition.
To see the full path to a particular file, you need to do several things: click on any file or folder and hold your finger until the menu appears. At the bottom of the screen or in properties (Details) often shows the current location of the object. In some versions of MIUI, the path can be seen in the top navigation bar.
For a deeper analysis, use the built-in cleanup function. Go to Settings β Memory. Here, the system will show you which file types take up the most space. This is a visualized map of your storage where you can click on the category and go to the files.

Use File Search in Explorer by entering an extension (e.g..mp4) to find all video files regardless of where they are located.
Using a PC to analyze memory
Connecting a smartphone to a computer opens access to the file system through a protocol MTP (Media Transfer Protocol, which allows you to see the folder structure as if it were on an external drive, and to get started, connect the device with the original cable to the external disk. USB-port.
Once connected, the phone will be asked to use USB mode, you must select File Transfer or Android Auto, and then the computer will be able to read the contents of the internal memory, and in My Computer, a device named your Redmi model will appear.
When you open the device, you'll see the root directory, which is convenient for mass deleting or transferring files, and computer programs for analyzing the disk, such as WinDirStat or TreeSize Free, work great with the connected phone, and they build a visual map of the occupied place.
The data transfer speed depends on the version USB-If copying is slow, try another port or wire. Do not remove the cable while writing the data so as not to damage the file table.
βοΈ Preparation for PC connection
Hidden folders and system debris
Many applications create hidden folders that start with a dot, which are not visible in standard mode, and to detect them, you need to enable the display of hidden files in Explorer settings, which is usually found in the three-dot menu or in the application settings.
The main source of garbage is the cache of browsers and social networks. The.cache folder or hidden directories in Android/data can grow to several gigabytes. Clearing this data is safe, but can lead to longer downloads of content the next time you launch applications.
Error logs and crash reports also take up space.They are often stored in the root directory or in the MIUI folder. Files with the.log or.txt extension with dates in the title can be deleted if you don't plan to send the report to developers.
The Thumbnails system folder stores thumbnails of images. It can weigh a lot. Deleting it will make room, but the gallery will be open longer on its first run, because it will have to recreate previews.
| Type of folder | Location. | Can I remove it? | Description |
|---|---|---|---|
| DCIM | /storage/emulated/0/DCIM | No (manually) | Photo and video from the camera |
| Download | /storage/emulated/0/Download | Yes. | Files from the Internet |
| Android/data | /storage/emulated/0/Android/data | Careful. | Cash and application data |
| MIUI | /storage/emulated/0/MIUI | Partially. | System Logs and Themes |
Cleaning the system partition "Other"
In memory statistics, there's a lot of "Other" categories, which may not be the size of the memory, and it's going to include files that the system can't classify, which can be archives, documents, remnants of remote applications, or messenger data.
To analyze this category in detail, it's better to use third-party tools like Files by Google or DiskUsage, which scan internal memory and show the space distribution as a graphics card, which allows you to find the "heavy" files hidden deep in the system.
Often, large volumes of Telegram or WhatsApp messengers are cacheed in the Other, and these apps store their correspondence and media history in their private databases, and it is better to clean up through the settings of the application itself, rather than through the file manager.
If the Other takes up a critically large amount of space (over 10-15 GB), it is recommended to back up important data and perform a factory reset, which is the only way to ensure that you remove system debris accumulated over the years of use.
Advanced Methods: ADB and root rights
For advanced users, it is possible to access through ADB (Android Debug Bridge) debugging, which allows you to see the file system as the system sees it, and you need to turn on Developer Mode and activate USB Debugging in the settings menu.
By connecting the phone to a PC with an ADB installed, you can execute a command to view all partitions. the adb shell ls -l / command will display a list of root directories. The df -h command is used to analyze the free space.
adb shell pm list packages -fThis command will show a list of all installed packages and the paths to their APK-This is useful for finding forgotten applications that take up space but don't show up in the standard menu.
Getting Root rights (for example, through Magisk) gives full access to all memory parts, including system ones. However, this cancels the warranty and can disrupt the operation of banking applications.
β οΈ Attention: Working with ADB A mistake in one command can lead to data loss or system failure.
