Owners of the popular Xiaomi Redmi Note 7 smartphone often face the need to check the available space on the device, which can be caused by slow operation of the system, reports of a lack of space for installing new applications or a desire to optimize the gadget. Understanding how internal memory is distributed and how much free RAM is the key to stable operation of the device.
Modern mobile operating systems like MIUI hide detailed technical parameters from the average user by placing them in the back of the menu. However, knowing the exact path, you will be able to get comprehensive information about the state of the drive. In this article, we will discuss in detail all the ways to diagnose storage on your device.
Don't ignore the system's disk space filling signals, and timely validation avoids critical errors in the camera, messengers, and banking applications, and let's look at where that data is and how to interpret it correctly.
Use of the Standard Security Application
The fastest and most affordable way to know the state of storage on Redmi Note 7 is to use the built-in system tool. Xiaomi preinstalles the Security app, which aggregates system data. Open the label with the shield on your desktop and find the Cleanup section. Here you will see a visualization of occupied and vacant space.
Click on Clean or just go to the storage section to see the details. The system will automatically analyze the files and suggest removing the garbage. However, for deep analysis, you'd better go to the settings of the application itself or use the menu button inside the cleaning section.
⚠️ Attention: The Cleanup feature in the Security app can aggressively remove the app cache. Make sure you don't lose important authorization data in some programs if you decide to do a deep cleaning.
The advantage of this method is that it is simple and doesn’t have to dig into the complex settings menu of Android.It’s ideal for quick check before installing a heavy app or game.
Verification through the system settings of Android
For more accurate and official statistics from the operating system, you should consult native settings. This path gives information that Android itself sees, without the add-ons of the MIUI shell. Go to the Settings menu, scroll down to About Phone and select Storage.
This shows the total capacity of the physical drive and the amount of space available, and it also shows how much space apps, images, videos and system files take up, and if you click on any category, you can see a detailed list of files sorted by size.
It is important to distinguish between ROM (permanent memory) and RAM (rAM). In the About phone section, you can also find information about RAM by clicking multiple times on the MIUI version or going to the advanced CPU settings if this option is activated by the developer.
💡
Use Full Screen mode in display settings to see more information about files in the list without scrolling the screen constantly.
Memory analysis by file category
Understanding the disk's filling structure is critical to the Redmi Note 7's optimization. It divides all data into several major categories, each with its own deletion and control features. Let's take a look at what's behind these names.
Multimedia files are the largest data source, and high-resolution photos and 4K video can take up tens of gigabytes of applications and data that tend to grow over time, accumulating logs, temporary files and cache.
System files and so on are a category that is hard to manually control, which includes update files, backups and backup data, and sometimes cleaning up the system cache through the recovery menu can free up a significant space in this category.
| Category | Description | Can I remove it? | Impact on the system |
|---|---|---|---|
| Annexes | Established programmes and their data | Yes (via settings) | High (deleting system apps is dangerous) |
| Images | Gallery photo, screenshots | Yes. | Low. |
| Video | Camera recordings, uploaded videos | Yes. | Low. |
| Audio. | Music, dictaphone, ringtones | Yes. | Low. |
| Systemic | OS files, update cache | Carefully. | Critical |
Regular monitoring of these categories allows you to keep your device in good shape, for example, messengers like Telegram or WhatsApp can stealthily take up 5-10 GB of memory per month of active correspondence in groups.
Using a conductor for detailed viewing
Standard Explorer Explorer (or File Manager) gives you access to the file system as it physically exists. When you run an application, you'll see the categorization and the ability to navigate to the root directory. It's a powerful tool for manual file management.
Going to the root folder, you can find hidden directories that don't show up in standard galleries. Pay special attention to the Android/data and Android/obb folders. It stores cache and additional files of games and heavy applications. Deleting the contents of these folders can lead to resetting of game progress.
⚠️ Note: Do not delete files that you do not know the purpose of, especially in system folders.This can lead to unstable work of the Xiaomi Redmi Note 7 or a cyclical reboot.
The conductor also allows you to sort files by size, which is convenient for finding heavyweights occupying space. You can quickly find forgotten archives, old installations. APK-Error logs or files that weigh hundreds of megabytes.

Working with an external microSD memory card
Redmi Note 7 is equipped with a hybrid slot, allowing you to use the second SIM-MicroSD card or memory card: Installing a drive greatly enhances storage capabilities, but requires proper configuration; the system can use the card as a portable storage device or as part of internal memory.
When you first connect, Android will suggest formatting the card, and if you select the internal memory mode, the system will encrypt the card, and it will not be read on other devices without re-formatting, which increases data security, but limits the mobility of the card.
To view the memory card information, go to Settings → Storage, which will show the total volume, free space and speed of the drive, and it is recommended to use cards of the speed class UHS-I or higher for the comfortable operation of applications.
Cache cleaning and space optimization
Temporary files are a natural process for a smartphone, and cache speeds up the loading of frequently visited pages and apps, but over time, it becomes unnecessarily large, and regular cleaning helps free up gigabytes of space on the internal drive.
Cleaning can be done selectively for each application through the settings menu or globally through cleaning tools, but it’s worth remembering that once the cache is cleaned, applications can load a little longer on their first run, as they will have to recreate temporary files.
It's also recommended that you remove unused apps, go to your app settings, sort them by size or date of last use, and remove those you haven't used for more than a month, which will free up not only space, but also CPU resources.
💡
Regularly cleaning the cache and removing unused apps is the most effective way to keep the Redmi Note 7 running without losing personal data.
Remember to check the Downloads folder, which often downloads documents, presentations and installers that are no longer needed after use, and automatically cleaning this folder once a month will become a good habit.
