What does clear cache mean and how to do it? What does it mean to clear the cache on an Android phone? What does it mean to clear the browser cache

Cache on Android is data that applications create during their execution. They are necessary for faster operation of these programs. For example, image viewers create thumbnails of images so that they can be displayed immediately in the future, rather than loading the processor each time to create miniature copies. In the case of browsers, a cache is needed so that in order to display a site that was previously opened in the application, it does not load data that usually does not change (for example, images).

Although the cache stores useful data that allows the applications that created it to run faster and consume less power, it can sometimes cause one significant inconvenience to the user - leading to a lack of storage space. This is understandable, because over time a lot of corresponding files may appear, and some of them will be of an impressive size.
For example: if, say, 25 applications are installed on the device and are used regularly, then after a month the cache will most likely grow to 7 gigabytes, and possibly more. If the device has only 32 gigabytes of storage, then having such a large amount of relevant data will become a problem. As a result, you will need to clear the Android cache.

What are the dangers of clearing the cache?

In general, clearing the cache in Android is completely safe, with only one exception - you can lose unsaved information in running applications. Therefore, before clearing the cache, you need to save all the information that is important to you in already running applications.

Types of cache

The cache in the Android operating system is divided into three types:

1. Dalvik-Cache;
2. system cache;
3. application cache.

Dalvik-Cache is data created by the Dalvik virtual machine. It stores optimized application files that are needed for faster program execution. Those, in turn, are located on a special section that is invisible to a user who does not use special applications.
In the system cache The data of programs that are built into Android is stored. During operation, the system creates files in which it records information that can be reused.
The application cache is a storage of data that was created by third-party applications (for example, downloaded from the Play Market). It may contain: thumbnails of pictures, images downloaded in the browser, game files, etc.

Basic ways to clear cache in Android

The system and application cache can be cleared in two ways: using the built-in utility and using one of the special programs that are available in the Play Market.
Deleting the cache using the built-in utility is a safer way to get rid of the corresponding data. The system is guaranteed not to harm files that are necessary for the operation of programs and the system, as well as user information. When working with third-party applications, in turn, you should be more careful.

How to clear cache on Android manually

Now let's move directly to the question of how to clear the cache on an Android phone.
To delete the corresponding data without using third-party software you will need:

• go to “Settings” (through the menu or curtain);
• find the “Device” category and select “Memory”;
• click on the “Cache Data” item;
• In the pop-up dialog box, click “Ok”.

After a few seconds (the exact time depends on the volume of accumulated files), the mentioned window will disappear, and the “Available” value will increase by a number equal to the number of megabytes/gigabytes that was previously indicated in “Cache Data”.

How to clear the cache of just one application

Now about how to clear the cache on Android for only one specific application. To do this you will need to perform the following series of actions:

• go to “Settings”;
• select “Memory”;
• tap on “Application data...”;
• go to the “All” tab;
• find and select the application whose cache you want to clear;
• on the screen that appears, click on “Erase data”;
• Confirm the action by clicking “Ok”.

After a few seconds, the cache data of this application will be deleted.

After deleting application data, you may need to log in again (for example, in the case of social network clients). Therefore, before cleaning, make sure that you have access details for the account you want to connect to through the application.

Android apps to clear cache

One of the most popular applications that allows you to clear the cache on Android is. This program can be downloaded for free from the Play Market. It's easy to use:

• First you need to download and install it;
• Once launched, you will need to click on the “JUNK FILES” button;
• on the screen that appears, you must select the applications whose cache you want to clear;
• Click on “CLEAN JUNK”.

This application can be configured to clear the cache at a specified time.
There are also other programs for clearing the cache, for example,

On any computer hard drive there is a small piece of space called the browser cache. It is a kind of storage where fragments of visited sites are collected. In order to save Internet traffic and spend as little time as possible connecting to the necessary resources, the browser is able to save some pictures and other content.

When you frequently visit various sites, your computer's performance decreases, because even after closing the resource, unnecessary files remain in memory. To get rid of this problem, you need to try to remove the excess. To do this, you need to understand how to clear the cache. This procedure is extremely simple, but it is still worth considering it more closely.

How to clear your browser cache

Absolutely all Internet browsers have a function that can be used to clear your browsing history. When developing any browser, an interface is created that is designed to partially or completely clear the cache. This procedure is needed to clear temporary information about the pages visited. To carry out this operation, you just need to open a special browser window and indicate which files are to be deleted. Each individual Internet browser has its own cleaning algorithm.

Yandex ("Yandex") browser

Instructions for users who do not know how to clear the cache in Yandex:

• Click on the icon in the right corner of the browser to open the menu.

To visit, delete sites and files that were downloaded from them, press Ctrl+H. The described combinations are relevant for all versions of Mozilla. If the actions taken do not speed up the work of the Internet browser, it makes sense to check the current version of the browser for relevance. Perhaps it just needs updating.

Google Chrome ("Google Chrome")

This Internet browser is widely considered the fastest, and if it starts to freeze, this is a signal that it urgently needs cleaning. Below are instructions that tell you how to clear the cache:

iPhone

Now let's look at how to clear the cache on an iPhone.

On an iPhone, first of all, you need to clear the Safari browser, and then find and download an application that will clear the iPhone’s memory. The best program for this purpose is Battery Doctor.

Many users of modern computers are familiar with the situation when the computer “thinks for a long time”; website pages load slowly, even if you visit them constantly. One of the main reasons for PC slowdown is a full cache. A cache is a storage of temporary information that takes up space in system memory, on your hard drive, and even in the Internet browsers you use.

Clearing the computer's memory cache. If the system memory cache is not cleared, temporary information will become permanent and may reduce system performance and cause computer applications to run slowly. To clear the memory cache, you need to create a shortcut on the desktop by right-clicking on it and selecting the “Create” – “Shortcut” option from the menu that opens. In the window that opens, enter the path to the file “%WINDIR%\system32\ rundll32 . exe ", where %WINDIR% is the directory of the computer in which the Windows operating system is located, and rundll32 . exe is an application used to run dll files. You can come up with any name for the shortcut you create, for example: “Clear cache” or “RAM Clear”. Run the program to clear memory. Clearing the DNS (Domain Name System) cache. Each site has its own individual IP address (for example, 125.0.0.5.). But remembering all the IP addresses of the sites you visit is simply unrealistic. To make it easier, users were offered letter designations for site names - site url (for example,). Each time they type a site name, the DNS service calculates which IP address the name corresponds to and provides the requested resource. To clear temporary files in the DNS service, you need to find the “ Command line": "Start" menu - "Programs" tab - "Standard programs" - " Command line" In the window that appears, enter the special command “ ipconfig/flushdns" and press the "Enter" key. In less than a minute you will receive a message in the Command Prompt window about the successful clearing of the DNS cache.

Clearing cache trumbs. db. Trumbs. db is a special Windows OS file that contains cached thumbnail images in a folder. It is created when you first visit a folder with images and is stored hidden. This file allows you not to generate thumbnails of unchanged pictures every time you visit a folder, thereby reducing the load on the system, increasing its performance. To clear the trumbnails cache, you need to find the “Utilities” item in the “Start” menu, launch the “Clean up disk” directory, select the disk that requires cleaning, and run the program by pressing the “OK” key.

Clearing the Internet browser cache. Clearing the cache of any Internet browser comes down to deleting various elements of Internet pages. Pop By adding them to the cache, these elements speed up the performance of sites when you visit them again. This information is useful if you constantly visit the same sites with the same page design. If the design (image or text on the page) has changed, this may lead to a data conflict and loading will be slower. The same thing will happen if the cache is very full. For example, in the Mozilla Firefox browser, in the menu located in the upper right corner, you need to open the “Settings” item, select the “Advanced” tab - “Network” - in the “Offline web content and user data” and “Cached web” Contents" press the "Clear Now" button.

CCleaner helps you delete temporary files from the system and all browsers you use simultaneously without opening each of them, empty the Recycle Bin, and check the system registry. In addition, the program is absolutely free. All you need to do is download, install and run CCleaner. In the program window that opens, configure the settings for scanning and cleaning the system by checking the boxes next to those places that you think need it. Clicking on the “Analysis” button displays system information about possible files to be deleted. Clicking the “Cleanup” button will delete files without the possibility of restoring them.

By periodically clearing your computer's cache, you not only increase the amount of free space on your hard drive, but also increase the speed of processing requests (launching a program, viewing photos/videos), by deleting unnecessary data.
