Slow smartphone operation, constant notifications about low space and the inability to install important updates are familiar symptoms of full memory. When the internal storage Android is full, the system begins to work with delays, and applications can crash at the most inopportune moment. Users often wonder: what to delete so as not to lose important contacts and photos, but at the same time return the device to its former speed?
In this article we will analyze in detail which files and folders can be safely deleted, and which are better left untouched. You'll learn how to find hidden "junk" files that take up gigabytes but don't do any good. We will look at both the built-in system tools and specific settings of popular applications.
Freeing up space is not just about deleting old pictures. This is a comprehensive approach to data management that includes clearing caches, working with cloud storage, and properly organizing files. By following our steps, you can return hundreds of megabytes or even several gigabytes of free space to your gadget.
Storage fullness analysis and system tools
Before you start thoughtlessly deleting files, you need to understand what exactly is taking up space on your device. Modern shells, such as those from Samsung or Xiaomi, have built-in disk space analyzers. They clearly show the distribution of memory between applications, images, videos and system files. Android, such as One UI from Samsung or MIUI from Xiaomi, have built-in disk space analyzers. They clearly show the distribution of memory between applications, images, videos and system files.
To start checking, go to the menu Settings → Device maintenance → Memory (the path may vary slightly depending on the model). Here you will see a color chart where each sector is responsible for a specific type of data. The system itself often suggests deleting unused applications or large files that you downloaded a long time ago and forgot about them.
Pay attention to the “Applications” section. Often it is social networks and instant messengers that take up the lion's share of memory due to the accumulated cache. By clicking on a specific application, you can see a detailed breakdown: how much space is occupied by the installation file itself, and how much is user data and cache. Cache - these are temporary files that speed up apps, but they can be safely deleted without losing personal data.
⚠️ Attention: Do not delete files from system folders manually through the file manager if you are not sure of their purpose. This can lead to unstable operation of the operating system or loss of settings.
Use the built-in “Clean Now” function in the device maintenance menu to quickly remove temporary files and advertising junk.
Clearing the application cache and messenger data
The fastest way to free up space is to work with the application cache. Social networks, such as Telegram, WhatsApp i VKsave every photo and video you view to internal memory. Over time, this “collection” can grow to tens of gigabytes, although you only viewed these files once.
In the settings of each messenger there is a section dedicated to the use of data. For example, in Telegram you can go to Settings → Data and memory → Memory usage and click the “Clear cache” button. This action will not delete your correspondence, photos and videos from the cloud - they will simply be downloaded again when viewed again, but will free up disk space right now.
A similar situation is observed in browsers. If you actively surf the Internet, the browser stores copies of pages, images and scripts. Clearing the browser history and cache through the menu Settings → Privacy → Clear history can return from 500 MB to 2 GB of free space depending on the intensity of use.
- 🗑️ Clear the cache of the Gallery application if you have recently deleted a lot of photos, but the space was not freed up.
- 📱 Check the autosave settings in WhatsApp and disable saving media to the gallery.
- 🌐 Delete downloaded maps in offline navigators if you are not planning trips.
- 🎵 Clear the cache of music streaming services if you listen to music only online.
☑️ Checklist for quickly clearing messengers
It is important to distinguish between the concepts of “Clear cache” and “Clear data”. If you choose the second option, the application will return to the state immediately after installation: you will lose logins, settings and local chat history. Use this function only for those apps that are ready to be configured again.
Removing duplicate photos, videos and screenshots
Media files are the main consumers of space on any smartphone. In a year of active high-resolution shooting, you can accumulate hundreds of gigabytes of data. Often, the gallery accumulates unsuccessful duplicates, blurry frames and screenshots that were relevant only at the time of creation.
Use the “Similar Photos” function in modern galleries or third-party applications to find duplicates. Artificial intelligence algorithms group similar images, allowing you to select the best option and delete the rest. It is also worth paying attention to the folder Screenshots (Screenshots). Often we take screenshots to quickly convey information, but forget to delete them afterward.
Video files take up even more space than photos. One minute of 4K recording can weigh hundreds of megabytes. Review the folder DCIM → Camera and delete long videos that are of no value. If you don’t feel comfortable deleting them, transfer them to your computer or cloud storage.
How to find hidden videos in instant messengers?
Often videos received in WhatsApp or Viber are saved in separate folders inside the internal memory, for example, WhatsApp/Video. They are not always visible in the general gallery feed, but they take up space. Go to the file manager and check the Android/media folder.
Don't forget to check the "Trash" folder in the gallery. In many smartphones, deleted files do not disappear immediately, but are stored there for another 30 days in case of recovery. To really free up space, you need to empty this trash bin as well.
Working with the Downloads folder and unused files
The Download (Downloads) folder often turns into a digital dump. Application installation files (APK), documents, presentations and archives downloaded from the Internet are automatically saved here. After installing the app, the installation file is no longer needed, but continues to lie dead weight.
Open the file manager and sort the files in the downloads folder by size. Delete all APK files, old documents in the format PDFthat you have already read, and archives with the extension .zip or .rarthe contents of which you have already unpacked. Users often forget about downloaded restaurant menus or tickets for events that have already taken place.
| File type | Extension | Can I delete? | Where is |
|---|---|---|---|
| Application installer | .apk | Yes, after installation | Download |
| Temporary file | .tmp | Yes, safe | Different folders |
| System log | .log | Yes, if not debugging | System/Logs |
| Document | .doc,.pdf | Only if not needed | Documents |
⚠️ Attention: Before deleting files from the “Downloads” folder, make sure that they do not include important documents, receipts or instructions that you may need in the future.
It is also worth checking folders created by third-party applications. For example, photo or video editors often create their own directories with draft projects. If you've finished working on a project and exported the final file, you can safely delete drafts.
Transferring data to a memory card and cloud
If the internal memory of the smartphone is limited, the logical solution would be to use external media. Many models Android support format memory cards microSD. You can transfer photos, videos, music and documents to them, freeing up precious internal space for the system and applications.
To transfer files, go to the file manager, select the desired files or entire folders, click the menu and select “Move” or “Copy”. Enter your SD card as the quality. Some phones allow you to make a memory card part of the internal memory (Adoptable Storage feature), but this can slow down applications if the card is of a low speed class.
An alternative to a physical card is cloud storage. Services like Google Photos, Yandex.Disk or Dropbox allow you to upload media files to the Internet and delete them from the device. B Google Photos there is a convenient “Free up space” button that automatically finds and deletes photos already saved in the cloud.
Using the cloud has its own nuances: you will need the Internet to access the files. However, this is a great way to back up important data without the fear of losing your phone. Set up automatic photo uploading via Wi-Fi so that the process happens unnoticed by you.
Deleting unused applications and widgets
Applications that you don’t use don’t just take up space. They can run in the background, consume RAM and drain the battery. Conduct an audit of installed apps. If you haven't opened an application in the last 3 months, most likely you don't need it.
Pay special attention to pre-installed apps from your phone manufacturer or carrier. Often they cannot be removed in the usual way, but they can be “Disabled”. This will hide the application from the menu and prevent it from launching, which will actually free up system resources. You can find this option in Settings → Applications.
Games are the heaviest applications. Modern projects can take up 5-10 GB of space along with a cache of textures and sounds. If you have completed the game and do not plan to return to it, feel free to delete it. When reinstalling, progress can often be restored through your account Google Play Games.
Regularly checking the list of applications and deleting unused software is the best prevention of memory shortages in the future.
Don't forget about widgets on the home screen. Although they take up little disk space, they consume RAM and CPU time to update information. Remove unnecessary widgets for weather, news or exchange rates if they are not critical to you.
Resetting settings as a last resort cleaning measure
If none of the above methods helped, and the phone still signals about lack of space, it is possible that a lot of errors and fragmented data have accumulated in the system. In this case, a full reset to factory settings will help (Factory Reset).
This procedure will delete absolutely all data from the phone: contacts, messages, applications and files. The device will return to the state in which you bought it in the store. This is guaranteed to free up all available memory and often solves problems with system brakes.
Settings → System → Reset settings → Delete all dataBefore performing a reset, it is critical to make a complete backup of your data. Use your Google account to save your contacts and settings, and manually copy photos and documents to your computer or to the cloud. Without a backup, you risk losing important information forever.
⚠️ Attention: Resetting the settings is irreversible Make sure that the phone is connected to a charger and has at least a charge. 50% so that the process is not interrupted due to battery drain.
What to do after the reset?
After the reset, do not restore all applications at once from a Google backup. Install only the most necessary apps manually. Often, automatic recovery returns the same “garbage” that you tried to get rid of.
Frequently asked questions. questions (FAQ)
Is it safe to delete the Android folder on your phone?
No, you cannot delete the entire folder. It stores application data and files Android it is forbidden. It stores application data and files OBG for games. If you delete it, games will no longer run, and applications will no longer run. will reset the settings. You can clean only the subfolder cache inside it, but it is better to do this through the phone settings.
Why does the memory fill up by itself after cleaning?
This is normal system behavior. Applications create a new cache for their work, messengers download new photos from chats, and the system creates logs to control. This process, you need to regularly clear the instant messenger cache and disable media autosaving.
How to clear the memory if the phone is very slow and does not open the settings?
Try to boot into safe mode (usually you need to hold down the power button and long tap on the “Shut down” icon on the screen. In this mode, only system applications are loaded, which can allow you to remove heavy third-party apps). If it doesn’t help, only resetting through the Recovery menu will help.
Does full memory affect Internet speed?
Indirectly - yes. When the memory is full, it is more difficult for the processor to manage files, and the clipboard works slower. This can lead to browser freezes when loading heavy pages, which is perceived as a problem with the Internet.
Is it possible to transfer the applications themselves to a memory card?
On modern versions Android this function is often hidden or missing. Application developers do not recommend transferring apps to an SD card due to low reading speed, which leads to crashes. It is better to transfer only photos, videos and documents.
