How to look and clean up memory on Xiaomi Redmi 7

Modern smartphone users often face a situation where the device starts to run slower or stops accepting new photos and messages. Owners of the popular budget model Xiaomi Redmi 7 are no exception, as the amount of built-in storage in this model is often limited to basic configurations. Understanding how to manage the available space is a key skill for extending the life of the gadget and maintaining its performance.

In this article, we will discuss in detail all the available ways to monitor the state of the drive. You will learn not only where to find accurate numbers, but also how to safely delete unnecessary files, transfer data to a memory card and optimize the operation of the MIUI operating system. Proper resource management avoids critical errors when installing updates or important applications.

Don’t ignore the system’s space-scarcity signals, as this can lead to unstable interface performance.We’ll look at the full-time analytics tools, hidden developer features, and proven manual cleaning techniques.Your Xiaomi Redmi 7 will run smoothly again if you set up storage options correctly.

Use of standard system settings

The easiest and most reliable way to find out the exact amount of free and occupied space is to consult the system menu. The MIUI operating shell installed on Redmi 7 provides detailed statistics directly in the settings section. To access this information, you need to unlock the screen and find the gear icon in the application menu or in the notification curtain.

Once you log in, you should scroll down to About Phone or select Warehouse if it's a separate category in your firmware version, and that's where you can see the total storage capacity of the internal drive, the amount of system files and the amount of space available to the user, and the numbers are updated in real time to monitor the situation.

The system also visualizes data by showing a colored fill scale. Internal memory is divided into several logical partitions, but the user usually sees only the amount of gigabytes occupied. Clicking on a specific category, such as "Apps" or "Images", you can see a more detailed breakdown by file type.

💡

The "Storage" section in the settings gives the most accurate and up-to-date information about the state of disk space without installing third-party software.

It's important to look at the "Other" item, which often takes up a significant amount of space, which may be hiding temporary messenger files, remnants of remote programs or cache streaming services, and checking this section regularly helps to free up hundreds of megabytes that would otherwise be wasted.

Analysis through the Security Application

Each Xiaomi smartphone has a proprietary Security app preinstalled, which serves not only as an antivirus but also as a powerful memory management tool. When you run it, you'll see a big Cleanup button showing the current amount of junk files, the first line of defense against overflowing on the Redmi 7.

Clicking on the janitor icon will scan the device for cache, advertising files and residual data, but for a deeper analysis, you should go to the menu of the application itself and select Clean or Storage Management, which is much more functional than a simple quick cleaning.

• 📱 Analysis of large files: the utility finds videos and archives that take up a lot of space, and suggests removing or moving them.
• 🗑️ Deep cleaning: scans folders with thumbnails photos, browser cache and temporary update files.
• 📦 Application management: shows a list of programs sorted by space occupied.

Using a built-in tool is preferable to installing third-party “cliners” that consume resources themselves. Clearing the cache through the security application is safe for personal data, since only temporary files are deleted, and this is especially true for models with a small amount of built-in storage.

⚠️ Note: When using the Deep Clean feature, carefully look at which files are marked for deletion so as not to accidentally erase important documents or saved passwords in the browser.

Working with a microSD memory card

Xiaomi Redmi 7 is equipped with a hybrid slot, which allows you to use the memory card to expand storage. This is critical, as built-in 16 or 32 gigabytes quickly run out. To view the information about the memory card, you need to insert it into the tray and go to the storage settings.

The system will suggest formatting the card, and there's an important choice: use it as a portable storage device or as part of internal memory, in the first case, the card will be visible as a separate disk, in the second case, applications and their data will be installed directly on it, expanding the system partition.

Settings → About Phone → Storage → SD- Card → Settings

If you choose formatting as internal storage, the system will transfer some of the data automatically. However, it is worth remembering that the speed of the card can be lower than the speed of the built-in module. For comfortable work, it is recommended to use cards of the UHS-I speed class or higher from trusted manufacturers.

Check the status of the card is done in the same settings menu, which displays total volume, occupied space and free space, and regularly check the health of the card, as when you write it actively, it can fail faster than the main drive.

Detailed analysis of memory applications

Most often, social networks and instant messengers eat up space on Redmi 7. Telegram, WhatsApp, Viber and TikTok tend to accumulate gigabytes of videos and images viewed. To see a detailed list, you need to go along the Settings → Apps → All applications.

You can sort them by size, and if you pick a heavy app, you'll be taken to the control menu, where you have a memory or storage button, and you'll see the size of the application itself, the amount of user data, and the cache size, and it's the cache that's often inflated to the unthinkable.

Clearing the cache of a particular app is an effective way to quickly free up space. For example, YouTube or Instagram cache can take up more than 1-2 GB after active use. Click Clear cache, and this volume will be instantly freed up without losing your logins and correspondence.

Some apps allow you to set up automatic cache cleaning in your internal settings, which eliminates the need to do it manually, and it is also worth checking the settings for autoloading media files in messengers and disabling saving all received images to the gallery.

Hidden folders and system debris

Beyond the obvious apps, there are hidden folders on Xiaomi Redmi 7 that don’t always appear in the standard gallery. Viewing them will require a file manager, such as built-in Explorer or third-party Total Commander.

Special attention should be paid to the MIUI and Android/data folder. The first can store error logs and themes, the second can store game and application data, and users often forget about downloaded files in the Download folder, where APK installers and documents accumulate.

• 📂 Thumbnails folder: Stores thumbnails of all the photos viewed, can weigh several gigabytes.
• 📂 folder Tencent/MicroMsg: Here are stored all received files WhatsApp and WeChat.
• 📂 folder DCIM/.thumbnails: Gallery cache that is safely removed but recreated the next time you run.

Deleting the contents of the.thumbnails folder can temporarily speed up the gallery and free up space, but when you view the photo, it will fill up again, so it makes sense to clean it only if there is an acute shortage of space before you shoot an important video.

⚠️ Warning: Be extremely careful when deleting files in the Android folder. Deleting the wrong files can cause game progress or app errors to reset.

Optimization and prevention of overflow

To prevent memory loss from returning on the Xiaomi Redmi 7, you need to implement a habit of regular prevention. MIUI can remind you of the cleanup itself if you turn on the appropriate notifications in the Safety app, which helps keep your finger on the pulse.

Use cloud storage, such as Google Photos or Yandex.Disk, with autoload and delete from the device. This allows you to store the original photos in the cloud, freeing up local memory.

💡

Set up Google Photos’ “Free Space” feature to automatically remove photos and videos from your phone that have already been successfully uploaded to the cloud.

It's also worth revising the installed app list, and if you haven't used it for more than a month, you'd better remove it. In the era of cloud services, many apps (like banks or stores) have lightweight web versions that don't take up disk space.

Regularly rebooting your smartphone once a week helps the system reset temporary files and complete the hanging processes that can block memory cleanup.It's a simple but effective measure to keep your Redmi 7 healthy.
