Any active smartphone user sooner or later faces a situation where the device’s internal memory is rapidly filling up. Often the culprits are not the applications themselves, but the temporary data they accumulate during operation. This data is called cache files, and its volume can reach tens of gigabytes, significantly slowing down the system.
Understanding that where are the cache files on Androidgives you complete control over the storage of your gadget. Unlike iOS, Android's file system is open to browsing, but access to critical directories has been restricted in recent versions of the OS for security reasons. However, knowing the exact paths, you can manually remove garbage or transfer data.
In this article we will analyze the structure of the file system in detail, show hidden folders and explain the difference between the user and system cache. You will learn which files can be deleted without fear of breaking the application, and which files are strictly prohibited from being touched.
Android file system architecture
The file system Android is built on Linux and has a strict hierarchy. The root directory is indicated by the symbol /. For the average user, two main sections are available: internal memory and memory card SD. However, system processes operate in paths that are hidden from the standard My Files interface.
The application cache is usually stored in a special directory intended for temporary data. The system automatically manages this space, but often does so ineffectively. The path to this data is standard for most versions of the OS, from Android 4.0 to modern Android 14 and 15.
It is important to distinguish between the concept of “application cache” in the settings and physical files on the disk. When you click the "Clear cache" button in the settings menu, the system deletes the contents of a specific folder. If you want to do this manually through a file manager, you will need access to the root directory or use special software with rights. Root.
Use a file manager that supports access to system folders, for example, Total Commander or Solid Explorer, to see hidden directories without obtaining root access.
⚠️ Attention: Directly editing files in system partitions may lead to to unstable operation of the OS. Always back up important data before tampering with the directory structure.
Primary path to application cache files
The most common place where digital junk accumulates is the shared cache folder. Most apps write data here: browsers, social networks, instant messengers and games. The path to this directory is as follows:
/Android/data/Inside this folder you will find subdirectories with the names of packages of installed applications (for example, com.instagram.android or com.google.android.youtube). This is where downloaded pictures, temporary videos and logs are stored.
Starting with version Android 11, Google has introduced strict restrictions on access to the folder /Android/data/. Standard file managers now show it empty or hidden. This is done to protect user privacy, but complicates manual cleaning.
- 📂 The folder
cacheinside the application directory contains temporary files that can be safely deleted. - 📂 The folder
filesoften contains important data, such as offline maps or downloaded levels in games. - 📂 The folder
obbstores a cache of heavy games; deleting it will require you to re-download gigabyte data.
To bypass the restrictions of the new security system, you can use the built-in file manager or connect the phone to a PC in file transfer mode. On a computer, access to these folders often remains open, which allows for deep cleaning.
System cache and hidden directories
In addition to user data, there is a system cache, which is used by the operating system itself to speed up the launch of processes. These files are located in a protected section, which can only be accessed if you have root access.
The main path to the system cache looks like this:
/data/cacheThere is also a folder /data/dalvik-cache (or /data/art-cache in new versions), where optimized application files are stored for faster launch by the processor. Cleaning this folder is safe, but after a reboot the phone will “think” for a long time, re-optimizing all apps.
Another place where garbage accumulates is the folder /data/local/tmp. Some applications and scripts dump temporary data here. If you are not using your phone for development or complex debugging, you can check this folder periodically.
⚠️ Attention: Never delete files from the folder /data/data/ manually unless you know exactly the purpose of each file. This will lead to the loss of settings and the inability to launch applications.
To access these sections, you will need to install a file manager with support Root, for example, Root Explorer or Material Files with the appropriate rights. Without root access, you will only see the user part of the file system.
What is Wipe Cache Partition?
This is a procedure for clearing the system cache through the Recovery menu. It does not delete personal data (photos, contacts), but solves problems with freezes after system updates. Performed by a combination of the volume and power buttons when the phone is turned off.
Specifics of cleaning on different versions of Android
The approach to memory management has changed dramatically with the release of Android 10 and subsequent versions. If on older devices (Android 6-9) access to files was practically unlimited, now the system is trying to isolate applications from each other.
The table below compares the availability of cache paths on different OS versions:
| Android version | Access to /Android/data | Access to the system cache | Recommended method |
|---|---|---|---|
| Android 6 - 9 | Full access | Only with Root | Any file manager |
| Android 10 | Limited access | Only with Root | Application settings |
| Android 11 - 13 | Hidden (special access required) | Only with Root | Connecting to PC |
| Android 14+ | Strictly isolated | Blocked | Built-in cleaning |
On modern smartphones Samsung, Xiaomi and Pixel manufacturers implement their own algorithms cleaning that works more efficiently than manual removal. The system itself detects outdated files and offers to delete them.
However, if the built-in tools fail, using a computer remains the most reliable way. By connecting the device via USB, you get access to the file system at the protocol level MTP, where restrictions are often less strict.
On Android 11 and higher, standard file managers will not show the contents of the Android/data folder. Use a connection to a PC or specialized utilities with permission to access system folders.
Cache of messengers and social networks
Messengers such as Telegram, WhatsApp i Viberdeserve special attention. These apps create huge amounts of cache, storing every photo and video you view on your device. The paths to their data may differ from the standard.
For example, Telegram by default stores media files in shared memory and not in a protected folder /Android/data. The path often looks like /Telegram/Telegram Images or /Android/media/org.telegram.messenger. This makes it easy to find and delete old files through the gallery.
In the case of WhatsApp, the structure is more confusing. Media files are duplicated in the folder WhatsApp/Media and in the application system directory. When deleting the cache through the phone settings, you will clear only temporary files, but downloaded pictures will remain in place.
- 🗑️ To clear Telegram it is better to use the built-in function: Settings → Data and memory → Memory usage.
- 🗑️ In WhatsApp go to Settings → Data and storage → Storage management to delete large files.
- 🗑️ Social networks (VK, Instagram) store the cache strictly in
/Android/data, access to which is limited to new OS.
Regularly clearing the messenger cache can free up from 5 to 20 GB of space. This is critical for devices with a small amount of built-in memory.
⚠️ Attention: Messenger interfaces are updated frequently. If you do not find the storage management item in the specified location, check the "Storage" section in the general application settings.
Cleanup automation and useful utilities
Manually searching for and deleting files in the depths of the file system is tedious and risky. For these purposes, there are special utilities that use system APIs to safely clear the cache without the need for root access.
One of the effective tools is the application Files by Google. It analyzes the contents of folders, finds duplicates, memes from chats and temporary files, offering to delete them with one click. The application runs in the background and regularly reminds you to clean.
Another option is to use the manufacturer’s built-in tools. Shells MIUI, OneUI and ColorOS have pre-installed cleanup managers. They have access to system partitions that are closed to third-party applications and can clear the cache more aggressively.
☑️ Regular memory cleaning plan
Do not abuse aggressive “cleaners” that promise to speed up the phone 10 times. Often they simply kill background processes, which the system immediately restarts, wasting even more battery power. It is better to set up automatic cleaning once a week.
Is it possible to delete the Android folder completely?
No, you cannot delete the entire folder Android . This will reset all application settings, loss of game saves, and system errors. You can only delete the contents of subfolders cache within specific applications.
Why does the cache grow again after clearing?
The cache is working data. The application needs to load interface images, fonts and temporary logs for fast operation. If the cache is empty, the application will run slower and consume more traffic by downloading data again.
Does clearing the cache affect the battery?
Indirectly, yes. If there is critically little space on the phone (less than 1 GB), the system begins to work in intensive recording and rewriting mode, which heats up the processor and drains the battery. Freeing up space normalizes the operation of the memory controller.
Where can I find the Chrome browser cache on Android?
Physically it lies in /data/data/com.android.chrome/cache (available only with Root). It is easier for the user to clear it through the menu of the browser itself: Settings → Privacy → Clear history → Cached images and files.
Is it safe to use cleaning apps?
Use only trusted applications from well-known developers (Google, Samsung, Xiaomi). Questionable utilities may contain advertising, miners, or collect your personal data under the guise of optimization.
