You open your smartphone settings, go to the storage section and see a frightening picture: the “Other” (or “System Data”) category takes up tens of gigabytes, and it is not clear what exactly is stored there. This is a common problem on Android that often causes confusion among users trying to free up space for new photos or apps. Unlike the “Applications” or “Images” section, this category does not have a clear link to specific content visible to the user.
In fact, this name hides a collection of various system files, temporary data and cache, which the operating system considers important for its operation, but does not classify as standard types of media files. Understanding the nature of this data is the first step to properly managing your device's memory without the risk of deleting important information. Next, we will analyze in detail the composition of this category and methods of safe optimization.
What the “Other” category consists of
The bulk of the data in this section is application cache. Messengers like Telegram or WhatsApp, browsers and social networks save thousands of temporary files to speed up content loading. Over time, these files accumulate, even if you haven't opened a particular chat or web page in a while. The Android system classifies them as “Other” because they are neither photos, nor videos, nor application installation files.
The second important component is system logs and error reports. The operating system continuously records event logs that help developers diagnose crashes. Usually these files take up little space, but with frequent software errors their volume can grow to several gigabytes. Also included here are temporary update files that were not automatically deleted after installing a new firmware version.
Messenger cache is the main space eater. Go to Telegram settings and check memory usage in the “Data and Memory” section to delete old files manually.
Don’t forget about downloaded files that the system could not correctly identify. If you downloaded an archive, a document of a specific format, or a file without an extension, it is almost guaranteed to fall into this category. In addition, some smartphone manufacturers include here data on interface personalization and backup copies of settings.
Why the volume of “Other” is constantly growing
The growth in the volume of system data is a natural process of using a smartphone, but sometimes it happens abnormally quickly. The main reason lies in the algorithms of modern applications. Developers strive to make apps run as smoothly as possible, so they cache content aggressively. For example, when scrolling through a feed on a social network Instagram or TikTok, video fragments are saved in memory so that when viewing again you do not waste traffic and time on downloading.
⚠️ Attention: If the volume of the “Other” category has sharply increased overnight by several gigabytes, this may indicate a failure in the operation of any application that has cycled the logging or cache recording process.
Another reason is “dead” files. When deleting applications, their temporary files are not always erased correctly. They remain in the system folders, continuing to be listed in the general memory balance. Also, updating the operating system can create new structural files that were not previously taken into account in statistics or had a different priority.
In some cases, the users themselves are to blame for saving files in hidden directories. Downloading torrents, saving attachments from mail to service folders, or working with documents in cloud storage with offline access also replenish the “Other” reserves. The system sees this data, but does not know how to display it beautifully in the gallery or file manager.
Safe cleaning methods using built-in tools
The easiest and safest way to reduce the amount of space taken up is to use standard Android tools. Modern versions of the shell have a “Cleanup” function that analyzes the storage and suggests deleting unnecessary files. Usually it is in the menu Settings → Storage → Free up space. This tool can find duplicates, old screenshots and bloated cache.
For deeper cleaning, you should use the function of resetting the cache of individual applications. Go to Settings → Applications, select a heavy application (for example, a browser or instant messenger) and click “Storage”. There you will see a “Clear cache” button. It is important not to confuse it with the “Clear data” button, since the second one will delete your logins, passwords and correspondence.
☑️ Safe cleaning algorithm
Also an effective method is to empty the trash in the gallery and file manager. Deleted files often do not disappear immediately, but are moved to a special folder where they are stored for 30 days. They continue to take up space and may appear in overall statistics or related categories. Regularly checking the recycle bin helps maintain order.
If the built-in tools do not help, you can try clearing the cache of all applications at once through the Recovery Mode, but this requires caution. For an ordinary user, it is enough to periodically check the “Storage” section and delete files from the “Downloads” folder, which are often ignored by automatic cleaners.
⚠️ Attention: The settings interface may differ depending on the smartphone model and Android version. On devices Samsung, Xiaomi or Pixel the paths to the cleaning menu may be named differently.
Advanced cleaning via a computer and ADB
For experienced users for whom standard methods are not enough, it is possible to clean system partitions via a computer using USB debugging (ADB). This method allows you to delete files that are hidden from the user in normal mode, including remnants of uninstalled applications and the Dalvik system cache.
Before starting the procedure, you must enable developer mode and USB debugging in the smartphone settings. After connecting to your PC and installing the drivers, you can run the command to clear the package cache. This is safe, but requires care when entering commands in the terminal.
adb shell pm trim-caches 999999999This command will forcefully truncate the cache of all installed applications, freeing up space that the system considered reserved. You can also use the command to delete temporary update files, which often get stuck in the “Other” section after unsuccessful attempts to install software.
Risks of using ADB
Incorrect use of ADB commands can lead to the deletion of important system files or a crash in the interface. Use this method only if you understand the purpose of each command.
In addition to the command line, connecting to a computer in file transfer mode (MTP) allows you to manually enter hidden Android folders, such as Android/data and Android/obb. Gigabytes of data from games and applications often accumulate there and are not deleted when uninstalled. Manually deleting old folders with the names of deleted games can significantly free up space.
Storage analysis with third-party software
When built-in tools are powerless, specialized utilities for analyzing disk space come to the rescue. Apps like DiskUsage or Google's Files provide a visual map of your memory, showing you which files and folders are taking up the most space. This allows you to find the hero of the occasion, be it a forgotten movie in the YouTube cache folder or a 2 GB log file.
The use of such apps gives a clear idea of the storage structure. You will see not the abstract “Other” category, but specific files with paths to them. This is especially useful for finding large archives, database backups or forgotten downloads that the system could not categorize.
| Data type | Where to look | Can be deleted | Risk of data loss |
|---|---|---|---|
| Cache applications | Android/data |
Yes (via settings) | Low (loss of login settings) |
| System logs | Root folder (requires root) | Yes | Missing |
| Remaining updates | System partition | Yes (automatically) | Missing |
| Messenger attachments | Telegram/WhatsApp folders | Selective | Medium (loss of correspondence history) |
However, it is worth remembering that some memory “analyzers” themselves can create additional load on the system. It is recommended to use proven solutions from well-known developers, for example, utility Files by Google, which not only analyzes but also safely removes garbage, prompting the user to confirm the action.
Third-party memory analyzers are the best way to find hidden large files, but you need to delete them consciously, understanding the purpose of the folder.
Prevention and memory control
To prevent the “Other” category from growing to critical sizes, it is important to adhere to certain rules of digital hygiene. Regularly rebooting your smartphone at least once a week helps the system to automatically reset some temporary files and terminate frozen processes that create logs.
It is also worth setting up automatic cache clearing in popular applications. For example, Telegram has an “Auto-Delete Media” feature that prevents downloaded pictures and videos from taking up space forever. Browsers can set a limit on the size of the cache or configure it to be cleared when the application is closed.
Avoid installing dubious applications from unverified sources. Often such software contains malicious modules that generate a huge amount of garbage data in the background, masquerading as system processes. Use only the official store Google Play or proven alternatives.
⚠️ Warning: Full memory (up to 100%) can lead to serious malfunctions in Android, including cyclic reboots. Always leave at least 10-15% of free space for the system to function correctly.
Controlling system updates is also important. Before installing a major firmware, make sure you have enough free space, and after updating, check to see if there are any old version files left in the storage. Sometimes manually starting cleaning after a major update gives a better result than waiting for automatic processes.
Frequently asked questions (FAQ)
Is it possible to completely delete the “Other” section?
It is impossible to completely delete this category, since it contains files necessary for the system to function. However, you can reduce its size to a minimum (several hundred megabytes) by clearing the cache and removing garbage.
Is it safe to delete the Android/data folder?
Deleting the entire folder is dangerous - this will reset the settings of many applications. It is safe to delete only those subfolders inside that correspond to games or apps that you have already deleted.
Why does the space quickly fill up again after cleaning?
Most likely, you are actively using an application with a heavy cache (video, social networks) or there is a background process that creates logs. Check memory usage statistics by application for the last 24 hours.
Does the “Other” category affect the speed of the smartphone?
Yes, indirectly. If the storage is almost completely full, the system does not have enough space for temporary write operations, which leads to interface lags and slow application launches.
Do you need Root access to clear “Other”?
In most cases, no. Standard Android tools and permissions via USB debugging are sufficient for effective cleaning. root access is required only to delete deep system logs, which rarely gives a significant gain in space.
