Xiaomi Redmi 7A has proven to be a reliable budget device, but its modest memory characteristics often cause discomfort when operating actively. When internal storage is overflowing, the Android operating system begins to run slower, applications can freeze or spontaneously close.
There are many ways to optimize, from banal deletion of unnecessary files to deep cleaning of the system cache. the built-in Redmi 7A drive with a capacity of 16 GB or 32 GB fills up critically quickly due to the bloated system partition and the lack of ability to expand through the memory card on some modifications. Understanding the structure of the file system MIUI will help you manage resources efficiently without losing important data.
In this article, we will take a closer look at all the cleaning methods available to help your device get back to speed. You will learn which folders can be deleted without fear, how to transfer applications to an external medium and what hidden features of the Xiaomi shell are worth using. A competent approach to memory management will prolong the life of the smartphone and eliminate the need to buy a new device ahead of time.
Analysis of internal storage occupancy
Before we start taking radical measures, we need to determine exactly what is taking up precious gigabytes. MIUI It has a powerful analysis tool built in that visualizes the distribution of data. → Memory to see the detailed diagram, and you'll see the categorization here: apps, images, videos, documents, and so on.
Often, it turns out that the lion’s share of space is occupied not by user files, but by the cache of social networks and instant messengers. Telegram and VK tend to store all the media files viewed in the memory of the device, creating gigabytes of “digital garbage.” Without regular cleaning, these applications can take up to 10 GB or more, which is a critical volume for the Redmi 7A.
Also worth paying attention to is the Others section, which often hides residual files of deleted programs, error logs, and temporary update files.
⚠️ Note: Be careful when cleaning the Others section manually, as there may be installed program configuration files, the removal of which will reset application settings.
For a deeper analysis, you can use third-party tools like DiskUsage, which show the memory card as graphical blocks, which allows you to visualize the folders that are parasitic that are not displayed in the standard conductor, and understanding where your data is hiding is the first step to effective optimization.
Cleaning the cache and temporary files of the system
The fastest way to get free space is to clean up the app cache and the system. Cache is temporary data that speeds up the launch of programs, but over time grows and begins to slow down. First, use the built-in Security app, which is preinstalled on all Xiaomi smartphones. Run the scan and click the "Clean up" button.
However, standard cleaning often only affects surface debris. For more thorough processing, you need to go to the settings of each heavy application separately. Go to Settings → Apps → All applications, select the desired messenger or social network and find Memory.
It is important not to confuse cache cleaning with data cleaning. If you choose Clear Data, the application will return to the state immediately after installation: you will lose correspondence, authorization and settings.
⚠️ Warning: Clearing data in the applications of banks or messengers without prior backup will lead to a complete loss of access to accounts and message history.
There is also a hidden partition of the system cache that can be accessed through the Recovery menu, but on a Redmi 7A with a locked bootloader, this can be risky.It is better to limit software cleaning methods through the Android settings. Regular procedure frees up 500 MB to 2 GB of space, which is essential for budget models.

Managing Multimedia and Heavy Files
Photos and videos are the main memory consumer on any smartphone. The Redmi 7A camera takes pictures of acceptable quality, but files can take up a lot of space, especially if you were shooting in high resolution. First of all, check the DCIM → Camera and Pictures → Screenshots folder. Often there are hundreds of unsuccessful take and screenshots that have long since lost their relevance.
Modern cloud services allow you to offload the memory of the device by transferring media files to the Internet. Google Photos offers a function “Free space”, which removes from the device pictures already stored in the cloud. You can also use the Xiaomi cloud or Yandex.Disk to automatically upload the archive.
Remember the download folder. Browsers and instant messengers often automatically save open documents, APK installation files, and images viewed. The path to this folder usually looks like an Internal Drive → Download. Regular audit of this directory allows you to find forgotten files weighing several gigabytes.
To manage video files, use better compression codecs or convert long videos to a lighter format if you plan to store them on your phone. 1080p videos take up significantly less space than 4K, and on a smartphone screen the difference isn't always noticeable.
💡
Use Files by Google to find duplicate photos and large files that can be safely deleted, and it can find similar photos and suggest leaving only the best ones.
Transfer applications to memory card
Xiaomi Redmi 7A features a hybrid slot that allows you to use a microSD card. Although modern versions of Android are reluctant to port applications to external drives, this option still exists for some programs.
To try to migrate the application, paste the memory card formatted as internal storage (if MIUI version allows) or as portable storage. Then go to Settings → Applications, select the program and press Memory → Change. If the button is active, select the memory card.
Not all apps support portability. Google's system components and important services usually stay on the internal drive, but heavy games, navigation, and some social networks can be successfully moved to free up to a few gigabytes.
Below is a table showing which data types are best portable to an external map:
| Type of data | Possibility of transfer | Impact on speed | Recommendation |
|---|---|---|---|
| Photos and videos | Tall. | Minimum | Remove it, of course. |
| Music and Books | Tall. | Absent. | Remove it, of course. |
| Cash card (Navigator) | Medium | Average. | It is advisable to postpone |
| System applications | Low. | Critical | Leave it on the device. |
Using a fast memory card of a class U1 or U3 minimizes the loss of performance when you start applications from an external medium. Cheap and slow cards can, on the contrary, slow down the smartphone.
Removing System Garbage and Hidden Folders
In the Android file system, and in particular in the MIUI shell, there are folders that are created by applications for temporary storage of data, but are never automatically cleared, and can be accessed through a file manager, for example, Explorer from Xiaomi or Total Commander.
First of all, look at the Android → data folder, which stores all the installed games and programs. If you delete the game, but the folder with its name (for example, com.game.name) is left, you can safely delete it. It is also worth checking the folders with the names of social networks, where often stored statuses and avatars are stored.
Another “junk” area is a folder. MIUI → debug_log. It collects the debugging logs that developers need to find bugs, but the average user doesn't need them.
⚠️ Warning: Before deleting files from system folders, make sure you do not delete active application databases, otherwise the program may stop running or lose settings.
Also check for folders from long-deleted applications. Often, uninstaller only removes the shortcut and registry entry, leaving gigabytes of files on the drive. Manually checking the root directory of an internal drive once a month helps maintain order.

Use of special slits and Lite versions
If standard methods don’t work, it’s worth revisiting the set of installed applications. Many popular programs have “gluttonous” official versions that consume a lot of resources and space. For devices like Redmi 7A, the ideal solution is to switch to Lite versions.
Apps with the prefix Go or Lite (for example, Facebook Lite, Google Go, Skype Lite) are designed specifically for devices with limited memory. They take up 5-10 times less space and consume less RAM, retaining basic functionality.
There are also alternative clients, such as Telegram X or modified versions of browsers that do not accumulate gigabytes of cache. The abandonment of heavy applications in favor of web versions of sites can also significantly unload the system.
Regularly auditing installed programs will help you identify the space eaters, go to your memory settings and sort the applications by size, and if you see a program that you haven't used in six months and it takes 500 MB, feel free to delete it.
💡
Replacing heavy applications with their Lite counterparts can free up to 3-4 GB of internal memory without losing functionality for basic tasks.
Radical measures: Resetting to factory settings
When software cleaning and file transfer fails, the last, but most effective, method is to completely reset the device, which will return the smartphone to a store-like state by removing all user data, settings and applications.
Before doing this, it is critical to make a full backup. Use the built-in Mi Cloud or create a local copy on your computer or memory card. The path to create a local backup: Settings → About Phone → Backup and Restore.
Once you have created a copy, go to Settings → Advanced Settings → Reset and Reset → Reset. The system will warn you to delete all data. Confirm the action and wait for the reboot. This process can take from 10 to 30 minutes.
Once reset, the phone will work as fast as possible, as file system fragmentation and accumulated software debris will disappear, and this is the best way to give a second life to an old device if its hardware is working.
