Many smartphone users are faced with a mysterious situation when the device’s built-in memory quickly fills up, and visually free space disappears for no apparent reason. In the storage settings, you can find a category that is designated as “Other” or Other, and it takes up gigabytes, and sometimes tens of gigabytes of valuable space. This is a system partition that accumulates data that does not fall into standard categories like “Applications”, “Images” or “Videos”.
Understanding the nature of this section is critical to maintaining the performance of your Androidsmartphone. Ignoring the growth of this folder can cause the device to slow down, refuse to install updates, or even stop running heavy applications. In this article, we will analyze in detail the composition of this storage and propose specific methods for safe optimization.
The nature of the system partition “Other”
Partition “Other” on Android is not one specific folder that can be found through the file manager, but a collection of different types of data that the operating system classifies as system or temporary. This includes caches of installed applications, remnants of uninstalled apps, temporary system update files, and data that was not correctly recognized by the storage scanner. Often the volume of this section grows in proportion to the time the device is used without deep cleaning.
Files created by instant messengers and social networks occupy a special place in the structure of “Other”. For example, Telegram or WhatsApp can save media files in specific directories that the system does not always identify as “Photos” or “Videos,” sending them to a general heap. Error logs, reports on the operation of applications and data from offline maps of navigation services can also be stored here.
⚠️ Attention: Do not try to manually delete files from system directories through advanced file managers with root access without understanding their purpose. Removing critical system libraries may cause the phone to stop booting.
It is worth noting that memory categorization algorithms may differ depending on the manufacturer's shell. On smartphones Xiaomi, Samsung or Google Pixel the logic for assigning files to the “Other” section may vary. Sometimes there are files that the user downloaded from the Internet, but did not open, and the system marked them as unknown.
Periodically rebooting the smartphone (every 3-5 days) helps the system automatically clear some of the temporary cache files, which can slightly reduce the size of the “Other” section.
Main components that take up space
To effectively deal with memory shortages, you need to understand what exactly the category volume consists of “Other”. Most often, the lion's share is occupied by application cache files. This is temporary data that apps download to speed up work: image previews in the gallery, downloaded news feeds on social networks, temporary streaming video files.
The second significant component is the remnants of deleted applications. When uninstalling the app through the standard interface, some configuration files or user-downloaded data may remain in memory. Over time, such “tails” accumulate and occupy a significant volume. This also includes data from offline modes of various services, for example, downloaded maps in Google Maps or music in streaming services.
- 📁 Cache of system services and pre-installed software.
- 🗑️ Residual files after deleting games and applications.
- 📦 Archives of operating system updates.
- 📄 Logs of application operation and error reports.
Do not forget about files that the user created himself, but forgot about them. These could be forgotten downloads in format .zip or .rar, documents in office formats that the system did not classify as “Documents” due to the lack of an appropriate viewing application. All this settles in the “Other” section as a dead weight.
Analysis of occupied space using standard tools
The first step in the fight for free space should be a detailed analysis of the storage using built-in tools Android. Modern versions of the operating system provide fairly informative statistics screens. You need to go to the menu Settings → Storage (the path may differ slightly depending on the model, for example, Settings → Device maintenance → Memory on devices Samsung).
In this section, the system will show a visual diagram of memory allocation. By clicking on a category "Other", you can often see a more detailed breakdown. Some shells allow you to immediately go to the list of applications that take up the most space in this section. This allows you to take a targeted approach to the problem without clearing everything.
| Data type | Where to look | Deletion security |
|---|---|---|
| Application cache | Settings → Applications | Secure (data not are deleted) |
| Application data | Settings → Applications | Danger (resetting application settings) |
| Downloads | File manager | Safe (check files) |
| System logs | Hidden folders | Only through reset or special software |
Use the built-in “Cleaning” or “Optimization” function if it is available in your interface. It will automatically offer to delete unused files and clear the cache. However, manual control is always more effective than automatic algorithms, since you decide for yourself what is important and what is not.
A standard memory analyzer is the safest tool for initial diagnostics, since it does not have access to critical system files, the deletion of which is prohibited.
Manual clearing of cache and data applications
The most effective way to reduce the size of a partition "Other" is to work with the cache of individual applications. Go to Settings → Applications and sort the list by memory size. Pay attention to instant messengers, social networks and browsers - they are usually the leaders in space consumption.
Having selected an application, go to the section Storage inside its settings you will see two buttons: "Clear cache" and "Clear data". deletes temporary files, which is safe and does not affect your logins or correspondence. The second button completely resets the application to its factory state, deleting all accounts and settings.
⚠️ Attention: The “Clear data” button will delete all information inside the application, including correspondence in instant messengers (if there is no backup) and saved passwords. Use it only as a last resort.
For browsers such as Chrome or Yandex Browser, clearing the cache may temporarily slow down the loading of frequently visited sites, since images will have to be downloaded again. However, this frees up a significant amount of space. Regularly clearing the cache of heavy applications, such as TikTok or Instagram, should become a habit.
If the standard menu does not allow you to clear the cache of all applications at once, You can use the developer mode, but this requires caution. Under normal conditions, it is enough to go through the top 5 most “gluttonous” applications to free up several gigabytes.
☑️ Manual cleaning algorithm
Using specialized cleaning software
When built-in tools are not enough, third-party utilities come to the rescue, such as. like Files by Google, CCleaner or Clean Master. These apps can find duplicate files, residual garbage after uninstalling apps and large forgotten files.
The application Files by Google is one of the most reliable options, since it is developed by the search giant itself and does not contain intrusive advertising. the “Cleaning” function, which analyzes the device and offers to delete temporary files, memes from WhatsApp and old screenshots. The algorithms of such apps often see what is hidden from the standard memory manager.
However, you should be careful with aggressive “cleaners” that promise to speed up the phone significantly. Often they simply show ads and delete the same cache, which the system itself regenerates after an hour. Third-party utilities show the greatest effectiveness when searching for duplicate photos and large video files forgotten in the downloads folder.
- 🚀 Finding and deleting duplicate files.
- 🗑️ Deep cleaning of residual registry files (on rooted devices).
- 📊 Visualization of the largest files on the disk.
- 🛡️ Protection against malware (in some antiviruses).
Install such applications are only from the official store Google Play. Avoid dubious utilities that require suspicious permissions, such as access to contacts or calls, if their main function is to clear memory.
Why is space not freed up immediately after cleaning?
Sometimes the system takes time to recalculate free space. Try rebooting the device after the cleaner runs so that the data is updated correctly.
Radical methods: Reset and flashing
If the partition "Other" has grown to a critical size and cannot be cleaned by any methods, errors may have accumulated in the file system. In this case, the most effective, but radical method is to completely reset the device to factory settings. This action will erase absolutely all data from the phone, returning it to its "out of the box" state.
Before performing this procedure, it is vitally important to create a complete backup of all important data. Use cloud services Google Drive, synchronize contacts and transfer photos to your computer. After creating a backup, go to Settings → System → Reset settings and select "Delete all data".
⚠️ Attention: After resetting the settings, the phone will be completely clean. You will lose all your apps, photos, contacts, and settings if you don't back them up in advance. The process is irreversible.
An alternative to a full reset can be to flash the device via a computer using tools like Odin (for Samsung) or Fastboot (for other models). This allows you to reinstall the operating system while preserving user data (option flash without data wipe), but requires high qualifications and carries risks.
Often after a reset, users find that “Other” was taking up space due to a system bug or update conflict, which was eliminated by a clean installation of the OS. This is an extreme measure, but sometimes the only one possible to restore the functionality of the smartphone.
Before resetting the settings, remove the microSD memory card, if installed. This will protect your files on the card from accidental formatting if you make the wrong choice of disk for cleaning.
Prevention of memory filling in the future
To prevent the problem with the partition “Other” from returning, you need to develop habits of competent use of your smartphone. Check the folder regularly Downloads and delete installation files .apkthat are left after installing applications. They often take up space, but are no longer needed.
Set up automatic cleaning in messengers. In Telegram, for example, you can set the cache of media files to be automatically deleted if they have not been opened for more than 3 days or a week. This will prevent the accumulation of gigabytes of pictures and videos that you watched once and forgot.
Use cloud storage for photos and videos. Services like Google Photos allow you to free up space on your device with the click of a button, deleting local copies of pictures already uploaded to the cloud. This keeps the main memory free for the system and applications.
Why can the “Other” section take up more than 10 GB?
A volume of more than 10 GB usually indicates the accumulation of a cache of streaming services (YouTube, Netflix), offline maps or a large number of media messages in instant messengers for a long period of use without cleaning.
Is it possible to delete the Android folder completely?
No, you absolutely cannot delete the system folder Android entirely. This will cause all installed applications to not work and possibly cause the system to crash. You can clean only subfolders cache within it.
Does the size of the “Other” section affect the speed of the phone?
Yes, when the internal memory is more than 90% full, the speed of writing and reading data drops, which leads to noticeable interface slowdowns and a long startup applications.
How to find out which application created the file in “Other”?
This is difficult to do using standard tools. Use file managers with an analysis function (for example, DiskUsage) that visualize the folder structure and show the size of each directory.
Will “Other” disappear after updating Android?
Not necessarily. A system update may even temporarily increase this partition at the expense of installation files. However, major major updates sometimes recalculate the file system, which can correctly redistribute space.
