Owners of modern smartphones are often faced with a situation where the device starts to work slower or refuses to install new applications. The reason for this is often overflow internal storage. On brand devices Samsungrunning an operating system Android, finding this information can be confusing due to constant changes in the shell interface One UI.
Understanding where exactly the system information about occupied space is located is the first step to optimizing the operation of the gadget. Unlike older firmware versions, where everything was intuitive, modern menus require a more detailed dive into the settings. We will analyze all possible ways to access this data so that you can instantly assess the status of your drive.
You should not ignore system signals about lack of space, as this can lead to critical errors in the operation of important services. Next, we will look at the menu structure in detail and provide step-by-step algorithms for various models.
Navigation through the main settings menu
The most obvious and universal way to check the amount of available space is to use the standard settings application. This method works on absolutely all models, from budget series Galaxy A to flagship Galaxy S. You need to unlock the screen and find the gear-shaped icon, which is usually located in the notification shade or on the main screen.
After entering the menu, scroll down the list to the item, which may be called Device maintenance or Battery and device. In new versions of the shell One UI memory information is often placed on the first screen of this section. Here you will see a pie chart that clearly shows the distribution of space between applications, images, videos and system files.
Click on the section Memoryto get a detailed report. The system will analyze the data and show how many gigabytes have already been used and how many are left free. If the amount of free memory is critically low, the system itself will offer to run the optimization tool.
⚠️ Attention: The menu interface may vary slightly depending on the version of Android and the specific model of your Samsung smartphone. If you do not find the "Device Maintenance" item, look for the "Storage" section in the general list of settings.
Use the "Device Maintenance" widget on the main screen for quick access to the memory status without entering deep settings menus.
Using the "My Files" application
An alternative and often more convenient way to view the drive structure is a built-in file manager. The application My files (My Files) is pre-installed on each device Samsung and provides more flexible tools for working with data. It allows you not only to see the numbers, but also to immediately proceed to deleting unnecessary objects.
Launch the application and pay attention to the top of the screen. It usually displays summary information about the internal storage and, if available, about the memory card microSD. By clicking on the progress bar of the internal drive, you will be taken to a detailed analysis of file categories.
Here the data is sorted by type: Images, Video, Audio, Documents and Installed applications. This grouping helps to quickly identify “heavy” files that take up the lion’s share of space. For example, you can immediately see that the folder with downloaded videos from instant messengers weighs several gigabytes.
- 📂 The Downloads folder often contains forgotten APK installation files that can be safely deleted.
- 🗑️ The Trash in the Gallery and My Files app also takes up space in the internal memory until it is finally cleared.
- 📱 The cache of popular social networks can grow to incredible sizes without the user's knowledge.
Particular attention should be paid to the "Storage Analysis" section, which can be accessed through the app menu. This feature scans the device for duplicates, similar photos and rarely used applications, offering to delete them in one click.
Detailed analysis through the Applications section
Often users do not understand where exactly the free space goes, since visible files occupy only a small part of the memory. A significant amount is consumed by the applications themselves and their data. To figure this out, you need to go to the settings and select Applications.
In this list you will see all installed apps. Sort them by size by clicking on the sort icon (usually three stripes or arrows). You will immediately notice the leaders in resource consumption, such as Instagram, Telegram or YouTube.
By clicking on a specific application, you will be taken to the information screen about it. Here it is important to distinguish between the concepts Application size, User data and Cache. The size of the application is the weight of the app itself, user data is your logins, settings and downloaded content, and the cache is temporary files to speed up work.
| Data type | Description | Can I delete? |
|---|---|---|
| Application size | Basic app files | Only when deleting |
| User data | Personal information, chats, saves | No (will reset settings) |
| Cache | Temporary files | Yes, safe |
| Total size | Sum of all of the above | Depends on the type |
Clearing the cache is a safe procedure that will not affect your personal data or account login settings. However, clearing user data will return the application to the state immediately after installation, deleting all your chat history and authorization.
⚠️ Attention: Before clearing messenger data (WhatsApp, Viber, Telegram), make sure that you have a fresh backup of chats, otherwise you will lose your entire chat history forever.
Operation with a memory card and data transfer
Many smartphone models Samsung support expansion of internal memory using cards of format microSD. This is a great solution for storing media files, but it's important to understand the difference between an internal drive and an external card. The system sees them as two different logical drives.
You can transfer photos, videos and music to a memory card manually through the file manager. To do this, select the required files in the folder DCIM or Download, select the "Move" option and specify the path to the memory card SD card. This will free up valuable space in the internal partition.
Some applications allow you to change the location where files are saved in their internal settings. For example, in the camera you can set the photo to be saved directly to the card, and in music players you can select the path to the track library. However, the applications themselves and their cache most often remain in the internal memory for reasons of security and system speed.
Why can’t you transfer all applications to the card?
Modern versions of Android limit the transfer of applications to external media due to the low read/write speed of memory cards compared to the built-in flash memory, which leads to system slowdowns.
If you plan to enable the memory pooling feature (where the card becomes part of the internal memory), remember that this will format the card and make it unreadable on other devices without a reset. This option is not available on all models and firmware versions.
Hidden folders and system junk
In addition to the obvious files, there are hidden directories in the internal memory that consume space. These include system update folders, debug logs, and remnants of uninstalled apps. Access to them is often closed to the average user without obtaining root access, but some elements can be cleared using standard means.
The folder Android/obb i Android/dataoccupies a special place. Cache files of heavy games and additional application data are stored here. Deleting the contents of these folders may cause games to stop launching or require you to download resources again.
It is also worth checking the folder Lost.dir. The system dumps files into it that were not saved correctly when the power was suddenly turned off or the memory card was removed. If you are sure that there is no important data there, the contents of this folder can be deleted.
- 🔍 The folder
.thumbnailsstores thumbnails of photos and can take up gigabytes of space over time. - 📩 Email attachments downloaded automatically are also saved in the internal cache of the email client.
- 🔄 Temporary software update files may remain in the system after successful installation of a new version of Android.
To safely clean up system garbage, it is better to use built-in optimization tools than to delete files manually through a file manager with the display of hidden elements enabled. An error in selecting a file can lead to unstable operation of the interface.
☑️ Weekly memory cleaning
Resetting settings as a last resort
If none of the cleaning methods helped free up enough space, and the system continues to report a critical lack of memory, the problem may lie in deep system errors or data fragmentation. In this case, the option of completely resetting the device to factory settings is considered.
This procedure will completely delete all data from the internal storage, returning the phone to its “out of the box” state. Before this, you need to create a complete backup of your contacts, photos and documents in a cloud service Samsung Cloud or Google Drive.
To perform a reset, go to Settings → General settings → Reset → Reset data. The device will ask for confirmation and a password for your account. After rebooting, you will receive a clean system with the maximum amount of free memory.
⚠️ Attention: After resetting the settings, all installed applications will be deleted. You will have to sign in to your Google and Samsung accounts again, as well as configure security settings and biometrics.
Regular preventative cleaning of the cache and deleting unnecessary files is more effective than an emergency reset once a year.
Frequently asked questions (FAQ)
Why is the internal memory busy even though I didn't download anything?
System updates, application caches (especially social networks and browsers) and automatically created backups take up space without the user noticing. Also, part of the space is always reserved for the operation of the operating system and is not displayed as available to the user.
Is it possible to make a memory card the main internal memory on Samsung?
On most modern Samsung models, this function is officially disabled by the developers. The memory card is used only as additional storage for media files. Attempts to activate this function through third-party apps may lead to loss of warranty and unstable operation of the phone.
How to find the exact amount of internal memory without installing apps?
Go to settings, select the "Device Maintenance" or "Memory" section. It will indicate the total capacity of the physical drive and the available balance. Please note that the actual available volume is always less than that declared by the manufacturer due to the placement of system files.
Is it safe to delete the Android folder on your phone?
No, deleting the entire folder Android is strictly not recommended. This will cause all installed applications to malfunction, data loss, and possible system inoperability. You can clear only the contents of subfolders cache within specific application directories if you are confident in your actions.
