Smartphone owners Samsung often face a situation where free space on the drive is rapidly disappearing. Just yesterday 20 gigabytes were available, and today the system warns about a critical lack of space. This causes irritation and slowdown of the device. Phone memory is not just a storage of photos, it is a complex mechanism of the operating system, where every gigabyte counts.
To effectively deal with lack of space, you need to understand the nature of the occurrence of files. Android is a system that is in the process work generates a lot of temporary data. Some of them are deleted automatically, but a significant part accumulates over months. Users often blame only downloaded movies or games, overlooking hidden processes.
In this article, we will take a detailed look at the main categories of files that eat up gigabytes on your device. You will learn how to find hidden folders, why instant messengers take up so much space, and which system processes should not be touched. Understanding the storage structure is the first step to freeing up memory without losing important data.
Application cache and temporary files
The most common memory hog is the cache of installed apps. Each social network, browser or game saves temporary data to speed up loading of content when accessed again. For example, Instagram or YouTube can quietly accumulate gigabytes of watched videos and images. Application cache designed to optimize speed, but over time it turns into ballast.
⚠️ Attention: Clearing the cache in application settings is safe and will not delete your accounts or personal correspondence, unlike clearing data.
Many users confuse the concepts of “clear cache” and “clear data”. The first action deletes only temporary files, the second resets the application to its factory state, deleting logins and settings. To free up space on Samsung Galaxy it is enough to regularly clear the cache of the heaviest apps. The system One UI allows you to do this selectively through the settings menu.
Particular attention should be paid to browsers. They store browsing history, site thumbnails, and copies of web pages. If you actively surf the Internet, the browser cache folder can grow to several gigabytes. Regular maintenance in the section Settings → Applications will help keep this process under control.
Use the built-in Device Maintenance application on Samsung to automatically clear the cache of all applications with one click.
Media files in the DCIM and folders Pictures
The second most important source of memory filling is your own photos and videos. The standard folder DCIM/Camera contains all the pictures taken with the main camera. Modern smartphone matrices Samsung create high-resolution files, each of which can weigh from 5 to 15 megabytes. Video format 4K at 60 frames per second “eats up” space even faster.
In addition to the main gallery, there is a folder Pictureswhere screenshots, images from instant messengers and edited photos are saved. Users often forget about screenshots taken six months ago, which continue to take up space. This also includes downloads from social networks, unless otherwise specified in the browser or application settings.
| File type | Approximate size | Where it is stored |
|---|---|---|
| Photo (12 MP) | 3-6 MB | DCIM/Camera |
| Video (Full HD) | 100-200 MB/min | DCIM/Camera |
| Video (4K 60fps) | 400-600 MB/min | DCIM/Camera |
| Screenshot | 2-5 MB | Pictures/Screenshots |
To manage media files, it is convenient to use the application Google Photos or a standard gallery Samsung. The Free Up Space feature automatically finds pictures already uploaded to the cloud and suggests deleting their local copies. This is a safe way to get back gigabytes without losing access to the archive.
4K video takes up 4-6 times more space than Full HD. Re-shoot important moments in a lower resolution if memory is critically limited.
Messengers: hidden Telegram and WhatsApp folders
Messengers often become unexpected leaders in memory consumption. Applications like Telegram and WhatsApp by default save all received media files to internal memory. Telegram folder can grow to tens of gigabytes if you are a member of active channels with a large number of videos and pictures.
In the file structure Android messenger data often lies deep in system directories, for example Android/data/org.telegram.messenger. Users don't see these files in the regular gallery, but they take up space. In WhatsApp the situation is similar: the folder Media stores all forwarded videos and voice messages, even if you have already listened to them.
- 📁 Telegram: Check the settings "Data and memory" → "Memory usage" → "Clear cache". There you can set automatic deletion of files after 3 days or a week.
- 💬 WhatsApp: Go to "Settings" → "Data and storage" → "Storage management". The application will show the most voluminous chats.
- 🗑️ Viber: Often duplicates media files into a common gallery. Check the folder
Viberin the root of the internal drive.
Regularly clearing the messenger cache through their internal settings is much more effective than deleting it through the file manager. Internal tools allow you to delete old files, while leaving important correspondence and documents intact.
⚠️ Attention: Messenger interfaces are frequently updated. If you do not find the specified menu items, check the current paths in the official help of the application.
Where to look for hidden messenger folders?
On modern versions of Android (11 and higher), access to the Android/data folder is limited. Use Samsung's built-in My Files file manager or connect your phone to a PC to view the contents of these directories.
System files and firmware updates
The operating system One UI from Samsung itself takes up a significant amount of memory. Basic partition layout, system libraries and pre-installed services Google can reserve from 15 to 25 GB right out of the box. This is an unconsumable part of the memory that cannot be freed without losing the functionality of the phone.
Another important aspect is update files. After successful installation of a new version Android or security patch, the installation package often remains in memory. The files can be located in a folder Download or in a hidden system partition. The system also creates backup copies before updating, which sometimes are not deleted automatically.
In the "Memory" section in the phone settings there is a "System" item. If it takes up an abnormally large amount of space (more than 30-40 GB on a model with 128 GB of memory), this may indicate an indexing error or log accumulation. In this case, resetting the settings or clearing the cache of the recovery partition helps.

Downloads, documents and forgotten files
Folder Download is the “black hole” of the smartphone where all downloaded files from the Internet go. Instructions in PDF, installation files APK, music, documents from mail - all this settles here and is rarely deleted by the user. Often people download a file, open it and forget to delete it, thinking that it is needed “just in case.”
A special category is made up of application installation files. If you download apps not from Google Play, but from third-party sites, APK-files remain in memory after installation. They are no longer needed, but continue to take up space. It is also worth checking the folder Bluetoothif you have ever received files using this protocol.
To find large forgotten files, it is convenient to use the storage analysis function. In the "My Files" application there is a "Storage Analysis" section that groups files by type and age. This allows you to quickly find documents older than a year or huge video files that you forgot existed. Samsung There is a "Storage Analysis" section that groups files by type and age. This allows you to quickly find documents older than a year or huge video files that you forgot existed.
How to properly free up space on Samsung
The cleaning process must be systematic so as not to delete unnecessary things. Get started by using the built-in optimization tool. Go to Settings → Device maintenance → Memory. Click the "Clean Now" button. The system will offer to delete unnecessary files, duplicates and unused applications.
Next, manually go through the messenger and downloads folders. Remove old videos from the gallery by first saving them to a memory card or to the cloud. Don't forget about the trash can in the gallery - deleted files are stored there for another 30 days and continue to take up space.
Settings → Applications → [Select an application] → Storage → Clear cacheIf space is still low, consider transferring media files to the card microSD. In the camera settings, you can immediately set to save photos and videos to an external card. This will free up the internal memory for system operation and heavy applications.
⚠️ Attention: Do not delete files from folders with the names of system applications (for example, com.samsung.android...) if you are not sure of their purpose. This can lead to malfunctions of the phone.
Regularly emptying the recycle bin in the gallery and the Downloads folder frees up an average of 2-5 GB of space every month.
Frequently asked questions (FAQ)
Why does the memory fill up on its own, even if I do nothing downloading?
This happens due to the running of background application processes. Social networks cache the feed, instant messengers save media, and the system creates logs and temporary files. Without regular cleaning, this “digital garbage” accumulates.
Is it possible to delete the Android folder on Samsung?
Complete deletion of the folder Android is strictly prohibited. This will lead to inoperability of all installed applications and system crashes. You can clean only the contents of the subfolder cache inside it.
How to transfer applications to a memory card on Samsung?
On modern versions One UI i Android the function of transferring applications to a memory card is often disabled developers or is available only for certain apps. Check this in the settings of a specific application in the "Storage" section.
What is "Other" in the phone storage?
The "Other" category usually includes system files, application cache, game data, update files and documents that the system could not classify as photos or videos. Often this is where the bulk of the occupied space is hidden.
