Many users of Xiaomi, Redmi and Poco devices face a lack of free space, even though they do not even know that deleted files continue to take up precious gigabytes. The standard MIUI shell and its modern version of HyperOS introduce additional layers of data protection, one of which is a buffer zone for remote content. This feature prevents accidental loss of important information, but requires the smartphone owner to periodically manual intervention to finally free up disk space.
If you're used to just deleting unnecessary pictures or documents, it just moves them to a hidden partition where they can be stored for up to 30 days. Understanding how the deferred deletion mechanism works in the MIUI-based Android ecosystem will help you manage storage effectively. In this guide, we'll take a look at the nuances of working with the clipboard in various system applications.
Ignoring this procedure can cause the device's memory to fill up critically, causing the interface to slow down, so let's figure out where to look for these hidden folders and how to properly empty them.
The principle of operation of the buffer zone in MIUI and HyperOS
The file system architecture in the Chinese manufacturer's smartphones is designed so that when you press the "Delete" button, the data is not physically erased from the drive immediately, instead it is moved to a special system directory that the user sees as "Recently deleted" or "Recycle Bin", which is a security standard that allows you to recover files in the event of a user error within a certain time interval.
Unlike desktop operating systems, where the recycle bin can take up space indefinitely until the point of cleaning, mobile OSes have strict limits. Usually the system automatically deletes the contents of this buffer after 30 days, but this period can vary depending on the firmware version and the specific application.
⚠️ Attention: The process of cleaning the cart is irreversible. Once you complete the "Clean All" command, it becomes impossible to restore data with the usual system tools, so double-check the contents before final deletion.
It is worth noting that there is no single global shopping cart for the entire phone, and every application — whether it is a Gallery, Explorer or third-party messengers — has its own isolated buffer, which means that cleaning deleted photos in the Gallery will not affect files deleted through the File Manager.
Why are files not deleted immediately?
Cleaning the basket in the Gallery appendix
The largest storage of temporary files is usually the Gallery app, and this is where you get deleted photos and videos that can take up gigabytes of space, and you have to open the standard application to access this section and go to the Album tab.
At the bottom of the album list, you'll find a folder called "Recently Deleted," which stores all the media files you've erased in the last 30 days, and sorts them by date of deletion, allowing you to quickly find the right one.
To do the cleaning, click the menu button (three dots) or the "Select" button in the upper right corner of the screen, and you will be able to select individual files or use the mass delete function.
- 📸 Click "Select All" to highlight each file in the buffer for subsequent destruction.
- 🗑️ Use the Remove button at the bottom of the screen to clean the space.
- ⏳ Remember that without your intervention, files will disappear on their own 30 days after the initial deletion.
It’s important to consider that high-resolution video files like 4K or 60 FPS recordings take up significantly more space than regular shots, and cleaning up even a few of these videos from the basket can instantly free up a few gigabytes.

Cleaning up the “Recently Deleted” album at the Gallery is the most effective way to quickly regain free space on a crowded smartphone.
Delete files through File Manager
The second important component of the system is the built-in File Manager, which manages documents, APK installation packages, archives and downloads from the Internet, and its shopping cart is similar to a gallery but has its own interface features.
To access deleted files, run the Files app (yellow folder icon). You need to find the Recycle Bin item on the top menu or side menu (hamburger menu). In some versions of the shell, this item is hidden and only opens after you click on the menu icon.
It stores documents that have been manually deleted by the user, and is also limited to 30 days, after which they disappear forever, but unlike media files, documents are often deleted by users without verification, so the risk of losing an important agreement or check is higher.
Path to the basket: Files → Menu (three stripes) → Recycle binThe cleaning process is identical to the photo process: highlight the objects you want or select all at once, then confirm the action, and the system will request final confirmation, warning you that recovery is impossible.
☑️ Checking before cleaning
Automatic cleaning setting and storage time
Users often wonder if the standard storage life of deleted files can be changed: current versions of MIUI 13/14 and HyperOS have limited customization options, and the system tightly sets the 30-day interval for most file types.
However, it is possible to adjust the system behavior when memory is overflowing. Some cleanup scenarios allow you to automatically delete old files from the basket if the free space falls below a critical threshold (usually less than 500 MB).
To manage these settings, you should go to the settings of a particular application. In the Gallery, this can be done through the settings menu, where sometimes the option “Clean items older than 30 days” is available, which must be active by default.
| Type of application | Storage period | Possibility of change | Location. |
|---|---|---|---|
| gallery | 30 days | No (automatically) | Albums. → Recently deleted |
| Files (Conductor) | 30 days | No. | Menu → Basket |
| Google Photo | 60 days (for Pixel) / 30 days | Yes (in account settings) | Library → Basket |
| Text documents | 30 days | No. | Depends on the app. |
The lack of flexible storage time settings is due to security and optimization of the media database, and frequent defragmentation or change of time stamps can adversely affect the performance of the interface.
💡
Use the Cleanup widget on the home screen for quick access to the memory free feature, which often includes cleaning the cart.
Third-party applications and cloud services
The Android ecosystem involves a lot of third-party storage solutions, and users often forget that cloud services have their own shopping carts independent of the phone's memory, such as Google Photos or Yandex.Disk.
If you have sync enabled, deleting a photo in the phone gallery can cause it to be deleted in the cloud, but it can get into the cloud basket, which is an important nuance, because cloud storage has its limit, and overflowing it will stop synchronizing new data.
In Google Photos, the shopping cart is in the Library section, where files can be stored for up to 60 days if you own a Pixel device, or 30 days for other users, and cleansing is done in a similar way: through the selection menu.
⚠️ Warning: Cleaning the cart in the cloud service (e.g. Google Drive) will delete files from all devices that log in to this acca.
It is also worth checking messengers such as Telegram or WhatsApp, for example, there is a feature called “Recently deleted” on Telegram, which is only available for 48 hours after deleting a dialog or file.
Frequent problems and their solution
Sometimes users are faced with a situation where the shopping cart is not cleaned or files are returned after deletion, this can be due to errors in indexing media files or failures in the mediad process.
If standard cleaning doesn’t work, try clearing the Gallery app cache or File Manager. Go to Settings → Apps → All apps, find what you want and select Clear Cache. Don’t confuse it with Clear Data, as this will reset the settings of the application itself.
In rare cases, restarting the device in safe mode helps, which eliminates the influence of third-party plugins or miner viruses that can block the deletion of files. If the persists problem may require checking the file system for errors.
- 🔄 Reboot your smartphone to update system processes.
