Smartphone owners Samsung Galaxy often face a situation when the device starts to work slower or stops taking new photos. These are classic signs of overflow internal storage. Understanding how the file system is structured and where exactly your data is physically and logically located is the first step to competent maintenance of the gadget.
Modern operating systems Android, in particular the shell One UI from Samsung, have a complex partition structure. User access is limited to only a certain part of the total volume to ensure system stability. You can understand what is taking up space and how to manage it only by taking a detailed look at the folder structure and system settings.
In this guide, we will take a detailed look at file access paths, methods for analyzing occupied space, and safe optimization methods. You will learn to distinguish system files from user files and understand why deleting seemingly important data can lead to failures.
Logical and physical structure of the storage
Physically internal memory it is a NAND flash chip soldered on the motherboard of the smartphone. Unlike removable cards, this memory cannot be removed without special equipment. Logically, the space is divided into several partitions (sections), each of which is responsible for its own functions.
The operating system hides system partitions from the user, such as /boot, /recovery and /system. The section /dataremains available for management, which is displayed in the interface as “Internal storage”. This is where your applications, photos, downloads and cache are stored.
It is important to understand the difference between the total amount of memory declared by the manufacturer and that available to the user. Part of the space is reserved for the file system and work Android. On devices with 64 GB of memory, only about 45-50 GB may be available to the user.
⚠️ Attention: Attempts to gain root access to access hidden system partitions may lead to irreversible damage to the firmware and loss of warranty. Work only within user access.
Why is the amount of memory less than stated?
Manufacturers use the decimal number system (1 GB = 1000 MB), and the operating system uses the binary number system (1 GB = 1024 MB). In addition, part of the space is occupied by the Android system itself and pre-installed Samsung services, which cannot be removed using standard methods.
The folder structure in the root of the internal drive is standardized. Here are the directories DCIM for the camera, Download for downloads and Android for application data. Violation of the structure of these folders can lead to errors in the operation of apps.
How to find the path to files through the file manager
The easiest way to get to the files is to use the standard tool My Files (My files), pre-installed on all smartphones Samsung. It provides convenient access to all visible sections of the internal memory without the need to install third-party software.
To launch the application, find it in the menu or folder Samsung. Once opened, you will see categories (Images, Videos, Documents) and a list of folders. Switching to folder browsing mode opens the root structure of the storage available to the user.
Navigation is carried out by sequentially moving through directories. The path to frequently used files looks like Internal memory → DCIM → Camera for photos or Internal memory → Download for files downloaded from the Internet.
Use the "Search" function in the top panel of the file manager to instantly find a file by name or extension without manually going through folders.
If the standard application is not enough, you can install third-party managers such as Total Commander or Files by Google. They offer more flexible tools for working with archives and hidden files, but require care when deleting data.
When working with files, pay attention to extensions. System files often do not have an extension or have specific suffixes that only the OS understands. Changing or deleting such files may disrupt the operation of applications.
Analyzing space in the device settings
To get an overall picture of how full the memory is, it is not necessary to go through folders. The system Android provides a built-in analytical tool. Go to Settings → Device maintenance → Memory (the path may vary slightly depending on the version One UI).
A space distribution chart is displayed here. You will see how much applications, images, videos, audio, etc. take up. The system will also show the average file size in each category, which helps identify “heavyweights.”
Clicking on the “Applications” category will open a list of all installed apps, sorted by the amount of space they occupy. This allows you to quickly find games or social networks that are bloated with cache and data.
⚠️ Attention: The data in the “Other” section is often a cache of system processes or remnants of deleted applications. understanding, it is not recommended to forcibly delete files from this category through the file manager.
Regular monitoring of this section helps prevent critical memory filling. The system itself may offer to clear unused files if the automatic optimization function is enabled.
Hidden folders and system garbage
Many users do not suspect that a significant part of the memory is occupied by hidden folders in the file manager My Files need. enable the display of hidden files through the settings menu (three dots → Settings → Show hidden files).
After enabling this option, you will see folders starting with a dot, for example .thumbnails. This folder stores thumbnails of your photos for quick viewing in the gallery and can grow to several gigabytes.
Another one. the source of "garbage" is the folders of deleted applications. When uninstalling, apps often leave their configuration files and cache in the root of the internal memory. They can be safely deleted if you are sure that the application is no longer needed.
☑️ Checking hidden storages
Particular attention should be paid to the folder Android/data. Data from games and heavy applications is stored here. Cleaning this folder through the file manager on new ones. versions Android is limited by access rights, and the system may require special permission.
You should not delete files with unclear names in the root of the disk. Often these are temporary files (.tmp) or error logs that take up minimal space, but deleting them can cause malfunctions in the apps that created them.
Memory management using computer
Connecting a smartphone to a PC via a USB cable is one of the most effective ways to manage files. The computer sees the internal memory of the phone as an external drive, allowing you to use powerful file system tools Windows or macOS.
After connecting, select the file transfer mode (MTP) in the notification on the phone screen. A device with the name of your model will appear in “My Computer.” Double-clicking will open the root directory of the internal memory.
The advantage of working with a PC is the speed of copying and the ability to use “smart” search and sorting. You can quickly find all files larger than 1 GB or sort documents by date modified.
Requires an application| Action | Via phone | Via computer |
|---|---|---|
| Transmission speed | Low/Medium | High (USB 3.0) |
| Ease of sorting | Limited | Full control |
| Data security | High | Risk viruses from a PC |
| Working with archives | Built-in |
When working through a computer, it is important to complete the connection correctly. Use the “Safely Remove Hardware” function in the computer OS or the “Disable USB” command in the phone’s notification shade to avoid damage to the file table.
If the computer does not see the phone, check the drivers Samsung USB Driver and the integrity of the cable. Often the problem lies in using a charging cable without data lines.
Optimizing and transferring data to a memory card
Internal memory Samsung Galaxy takes precedence over the SD memory card, but some data can be transferred. In the camera settings, you can specify saving photos and videos directly to the SD card, which significantly saves space.
To transfer existing files, use a file manager. Select the desired folders (for example DCIM or Download), select “Move” and specify the target folder on the memory card (usually indicated as SD card).
Some applications allow you to change the storage location of data in their internal settings. For example, in instant messengers you can configure automatic saving of media files to the memory card, if such an option supported by the application version.
⚠️ Attention: Not all applications support working with a memory card. Transferring system applications or their data to an SD card can lead to unstable operation or complete failure of the app.
Regularly transferring media files to a memory card or cloud storage is the best way to maintain the performance of the internal memory without losing data.
Using cloud services, such as Google Photos or OneDrive (integrated into Samsung), allows you to free up space by saving copies of files on the Internet. The “Free up space” function automatically deletes local copies of already downloaded photos.
Regularly clearing the application cache through the phone settings also helps keep the system in good shape. Don’t be afraid to clear the cache - this is temporary data that applications will create again if necessary.
Frequently asked questions about Samsung internal memory
Why does the internal memory fill up even if I don’t download anything?
This occurs due to the accumulation of application cache, error logs, temporary update files and garbage from deleted apps. Messengers also constantly save received media files in hidden folders.
Is it possible to increase the internal memory of the phone programmatically?
It is impossible to physically increase the memory using software methods, such as creating a swap file. on a memory card, are only possible on rooted devices and can slow down the smartphone due to the low speed of SD cards.
Is it safe to delete the Android folder?
Absolutely not. Deleting the folder Android will lead to resetting all applications, loss of progress in games and possible loss of game progress. inoperability of the system. You can only delete the contents of folders of specific deleted applications inside it.
How to find the actual amount of internal memory?
The exact information can be seen in the menu Settings → Device maintenance → Memory. The actual volume is always less than stated due to the peculiarities of converting units of measurement and system files.
What to do if the phone says “Memory is full”, but there are files?
Try to reboot the device. If the problem is not solved, check the “Trash” folder in the gallery and file manager - deleted files may take up space for 30 minutes. days. Also clear the cache of the Media Service application.
