Every smartphone owner sooner or later encounters an unpleasant notification about a lack of free space. The system offers to delete unnecessary files, but even after cleaning photos and videos, the mysterious partition continues to occupy gigabytes. Users often call this segment “garbage”, not understanding its true nature and importance for the operation of the operating system.
In fact, the “Other” category (or “System data” depending on the version Android) is not just a chaotic accumulation of errors, but a structured set of temporary files, application caches and system logs. Understanding what exactly is stored there will allow you to safely free up valuable space without risking damage to the device's performance. Let's take a look at what this volume consists of and why it is growing so quickly.
The nature of the “Other” section in the Android system
The section “Other” is a collection of data that the operating system cannot clearly classify as photos, videos, audio files or application installation packages. This is a kind of buffer zone where temporary files are accumulated, necessary for quick loading of frequently used apps and correct operation of the interface. If the system re-generated this data every time, the smartphone would work noticeably slower.
The bulk of this section is occupied by application cache. Social networks, instant messengers and browsers save thumbnails of images, copies of viewed pages and temporary media files so that when accessing again, they do not waste traffic and time on downloading. Over time, the size of such storages can reach tens of gigabytes, especially in applications like Telegram or TikTok, where the user consumes a huge stream of content.
This also includes system logs, update files that were not deleted automatically, and offline map data. It is important to understand that deleting some of these files may lead to a temporary decrease in performance, since the system will have to rebuild the cache. However, if the space is critically low, cleaning this partition is the only correct solution.
Before radically cleaning the “Other” partition, make a backup copy of important data, since some system logs may contain information about the current configuration of the device.
The main categories of files that take up space
To effectively manage memory, you need to clearly understand what types of data are hidden behind the impersonal name. Most often, users don’t even suspect that old conversations in instant messengers or forgotten offline playlists take up the lion’s share of space. Let's look at the main components in more detail.
- 📱 Application cache: Temporary files that speed up the operation of apps, but grow to gigantic sizes with active use.
- 💬 Messenger data: Saved images, videos and voice messages from WhatsApp, Viber and other communicators, which are often duplicated in general storage.
- 🗺️ Offline maps and navigation: Loaded map areas in Google Maps or Yandex Navigatorwhich can weigh several gigabytes each.
- 🔄 Update files: Residual files after updating the system or applications, which for some reason were not deleted automatically.
Streaming services deserve special attention. Applications like Spotify, YouTube Music or Netflix save content for offline listening in this section. Even if you delete an application, its “tails” may remain on the system, continuing to take up space. Therefore, before cleaning, always check the list of installed apps.
How to find and analyze hidden files
Standard tools Android do not always provide detailed information about which application inflated the “Other” section. Deep analysis often requires the use of third-party tools or built-in developer functions. The standard file manager shows only the general picture, hiding the folder structure.
For more accurate diagnostics, you can use the utility Files by Google or similar disk space analyzers. They visualize the data, showing which folders are taking up the most space. Also a useful tool is the "Storage Usage" menu in the settings, where you can sort applications by the size of the data they occupy.
⚠️ Attention: When using third-party file managers with root access, be extremely careful. Deleting system files from folders/dataor/systemcan lead to the smartphone not working.
If you decide to use a computer for analysis, connect the device via USB and enable debugging mode. Commands adb allow you to get a complete list of files and their sizes. For example, the command adb shell du -h /data/data will show the data size of each application, which will help identify hidden memory hogs.
adb shell dumpsys package | grep"Package Name"This method is suitable for advanced users who understand the structure of the Linux file system on which it is based Android. For most users, standard storage settings will be sufficient, where you can see a breakdown by application.
Safe methods for cleaning storage
Cleaning the “Other” section should be carried out methodically so as not to delete the necessary data. The safest way is to clear the cache of specific applications through the system settings. This does not affect personal data, such as logins, passwords or correspondence, but frees up a significant amount of space.
To perform this operation, go to Settings → Applications, select a heavy application (for example, a browser or social network) and click “Storage”. There you will see a “Clear cache” button. Repeat this procedure for all applications that take up a lot of space.
☑️ Safe cleaning checklist
Also an effective method is to remove and reinstall “bloated” applications. When you reinstall Telegram or Instagram you get a clean version without the cache accumulated over the years. Don't forget to export important chats or settings beforehand if they are not saved in the cloud.
Periodic clearing of the cache of heavy applications (once every 1-2 months) prevents critical filling of the "Other" section and maintains system performance.
Using Developer Mode and ADB
For users who are not afraid of the command line, the tools ADB (Android Debug Bridge) open up opportunities for deep cleaning. With their help, you can delete the system cache and files that are not accessible through the regular interface. This is especially true for devices with a small amount of built-in memory.
Before you begin, you must activate developer mode. To do this, go to Settings → About phone and quickly click on the build number seven times. After this, a new item “For Developers” will appear in the menu, where you need to enable “USB Debugging.”
By connecting your smartphone to the PC, you can run a command to clear the cache of all applications at once, although modern versions Android limit some actions without root access. However, viewing logs and deleting temporary files from specific directories is possible.
⚠️ Attention: Settings interfaces and menu item names may differ depending on the manufacturer’s shell (MIUI, OneUI, ColorOS). Always check the official instructions for your device model.
Using automatic cleaning scripts requires caution. An incorrectly written script can delete not only the cache, but also application databases, which will lead to the loss of progress in games or app settings.
Table: Comparison of cleaning methods
To choose the best way to free up space, it is worth comparing the available methods according to their effectiveness and safety. Some methods give quick results, but require repetition, others are more radical, but reliable.
| Cleaning method | Efficiency | Data security | Complexity |
|---|---|---|---|
| Clearing cache in settings | Medium | High | Low |
| Reinstalling applications | High | Average (requires backup) | Average |
| Third-party cleaners | Low/Average | Average (advertising, access) | Low |
| ADB / Root commands | Maximum | Low (risk of failure) | High |
As can be seen from the table, standard cleaning through settings is the golden mean between safety and results. Radical methods should be used only in extreme cases, when other methods do not help.
Overflow prevention section
To prevent the problem from recurring, you need to change your smartphone usage habits. Regular prevention takes less time than dealing with the consequences of a full memory. Implement simple rules in the daily use of the device.
- 📅 Weekly audit: Spend 5 minutes a week to check heavy applications and delete unnecessary files.
- ☁️ Cloud services: Set up automatic uploading of photos and videos to Google Photos or Yandex.Disk with deleting local copies.
- ⚙️ Messenger settings: Disable autosave media files to the gallery in settings WhatsApp and Telegram.
It is also worth monitoring updates to the system itself. Manufacturers often optimize memory algorithms in new versions Androidwhich can have a positive effect on the size of the system partition.
Why does memory fill up on its own?
Modern applications use complex algorithms for preloading content. Even if you didn't open the app, it might have updated your news feed or map cache in the background, thinking you had free space.
Why doesn't the "Other" section shrink immediately after clearing the cache?
The system takes time to recalculate free space and index files. In addition, some processes can instantly recreate temporary files for their work. Try rebooting the device after cleaning.
Is it possible to completely delete the “Other” section?
No, this is impossible and dangerous. This section contains files that are critical for the operation of the OS. Deleting all data will lead to a system crash, endless reboot or data loss.
Does the size of the “Other” section affect the speed of the phone?
Indirectly - yes. If the memory is almost full (more than 90%), the system starts to work slower due to lack of space for_swap_files and temporary operations. Regular cleaning maintains performance.
Is it true that memory cleaners harm your phone?
Aggressive cleaners can constantly shut down system processes, causing your phone to waste more energy restarting them. It is better to use built-in memory management tools.
