您一定已经注意到，您手机的存储空间中有一部分被缓存文件占用。您设备上安装的每个应用程序都会增加缓存文件的数量。最初可能看起来不多，但随着设备上应用程序数量的不断增加，这些缓存文件开始占用大量内存；可用于存储照片和视频等个人文件的内存。
好消息是，如果你愿意，你可以收回这个空间。清除缓存文件以释放存储空间不仅是一个有效的想法，而且如果您的手机很旧并且存储空间不足，这也是必要的。在本文中，我们将解释什么是缓存文件以及是否应该摆脱它们。
如何清除 Android 手机上的缓存（以及为什么它很重要）(How to Clear Cache on Android Phone (And Why Is It Important))
什么是缓存？(What is Cache?)
缓存只是一些临时数据文件。如前所述，您使用的每个应用程序都会生成一些缓存文件。这些文件用于保存不同种类的信息和数据。该数据可以是图像、文本文件、代码行以及其他媒体文件的形式。存储在这些文件中的数据的性质因应用程序而异。它们也是特定于应用程序的，这意味着一个应用程序的缓存文件对另一个应用程序无用。这些文件会自动创建并安全地存储在保留的内存空间中。
缓存文件的作用是什么？(What is the function of Cache Files?)
应用程序(Apps)生成缓存文件以减少其加载/启动时间。保存了一些基本数据，以便在打开时，应用程序可以快速显示一些内容。例如，您的浏览器将其主页保存为缓存文件，以便在打开时快速加载。游戏可能会保存登录数据，这样您就无需每次都输入登录凭据，从而节省时间。音乐播放器(music player)可能会保存您的播放列表，以便在打开时不必刷新和重新加载整个歌曲数据库。这种方式缓存文件的一个重要目的是减少我们使用应用程序的等待时间。这些缓存文件是动态的并不断更新。旧(Old)文件被新文件替换。存储在这些缓存文件中的数据会随着应用程序或个人设置的变化而变化。
为什么要删除缓存文件？(Why should you delete Cache Files?)
通常，不需要手动删除缓存文件。如前所述，这些缓存文件是动态的，一段时间后会自动删除。新的(New)缓存文件由取代它的应用程序生成。但是，在某些情况下，有必要清除缓存文件。现在让我们来看看这些情况：
1.缓存文件由应用程序保存以加快加载时间。但是，有时这些缓存文件会损坏并干扰应用程序的正常运行。损坏的缓存文件可能导致应用程序出现故障、滞后甚至崩溃。如果某些应用程序无法正常运行，则应清除其缓存文件以修复错误。
2.这些文件也占用了相当大的空间。尤其是(Especially)浏览器和社交媒体应用程序将大量数据保存为缓存文件，这会占用大量内存。为了释放空间，有必要不时清除旧的缓存文件。然而，这是一个临时解决方案，因为应用程序会在您下次打开应用程序时生成新的缓存文件。
3. 某些应用程序会在缓存文件中保存私人和敏感信息，例如您的登录凭据或搜索历史记录。这构成了安全威胁。如果其他人能够获得这些缓存文件，那么您的隐私就会受到损害。他们甚至可以利用您的身份进行渎职，责任将落在您身上。因此，在Android(Android)上清除缓存文件的另一个原因是避免安全威胁。
4. 最后，如果您发现您的应用程序（例如Instagram或浏览器）停留在同一个提要上并且不会刷新和加载新帖子，那么清除缓存文件将强制应用程序重新加载并显示新内容。
4 种方法来清除 Android 手机上的缓存(4 Ways to Clear Cache on Android Phone)
有多种方法可以清除Android设备上的缓存。您可以一次性清除单个应用程序或所有应用程序的缓存文件。如果您不想手动删除这些文件，那么您也可以选择第三方应用程序来进行投标。在本节中，我们将详细讨论各种方法，并为您提供清除缓存文件的分步指南。
方法一：清除所有缓存文件(Method 1: Clear all Cache Files)
Android系统允许您一次性摆脱所有应用程序的缓存文件。这不仅节省了时间和精力，而且瞬间清理了大量空间。尽管简单方便，但这种方法很少使用，因为它适得其反。如果你一次性删除所有缓存文件，那么下次打开它们时，你必须登录到每个应用程序。事实上，新的安卓(Android)版本，即安卓8（奥利奥）(Android 8 (Oreo))及以上版本已经取消了一次性删除所有缓存文件的选项。如果您使用的是较旧的Android设备并想清除所有缓存文件，请按照以下步骤操作：
1. 打开手机设置(Settings)。
2. 现在点击存储和内存(Storage and memory)选项。
3. 在这里，您会看到各种文件和应用程序占用内存的分析报告。
4. 向下滚动并点击缓存数据(Cached data)选项。
5. 现在屏幕上会显示一条弹出消息，询问您是否要清除所有应用程序的缓存数据。单击(Click)是按钮。
6. 这样做会清除您设备中的所有缓存文件。

方法 2：删除单个应用程序的缓存文件(Method 2: Delete Cache files for Individual Apps)
这是清除缓存文件的更常见和常用的方法。如果特定应用程序崩溃或无法正常工作，您需要删除该应用程序的缓存文件。除此之外，如果主要目标是释放空间(free up space)，那么只需选择占用更多空间的应用程序（通常是浏览器和社交媒体应用程序）并删除它们的缓存文件。请按照以下步骤了解如何删除或清除Android手机上单个应用程序的缓存文件：
1. 转到手机上的设置。(Settings)
2. 单击应用程序(Apps)选项以查看您设备上已安装应用程序的列表。
3. 现在选择您要删除其缓存文件的应用程序(select the app whose cache files you would like to delete)并点击它。
4. 单击存储(Storage)选项。
5.在这里，您将找到清除缓存和清除数据(Clear Cache and Clear Data)的选项。单击(Click)相应的按钮，该应用程序的缓存文件将被删除。
方法三：使用第三方应用清除缓存(Method 3: Clear Cache using a Third-Party App)
另一种清除缓存的有效方法是使用第三方应用程序。Play Store上有很多清理应用程序，它们不仅可以帮助您清除缓存文件，还可以帮助您清除其他垃圾文件。这些应用程序是释放内存并增加RAM的好方法。市场上一些最好的应用程序是：
1. Clean Master：这是(1. Clean Master: )Play 商店(Play Store)中最受欢迎的清洁应用程序之一，下载量超过 10 亿次。Clean Master允许您清除缓存文件、系统垃圾、未使用的应用程序数据、重复文件等。它还可以清除后台进程以释放RAM。除此之外(Apart)，Clean Master还有一个省电实用程序和一个防病毒系统。
2. CC Cleaner： 您可以尝试的另一个有用的应用程序是CC Cleaner。除了(Apart)Android之外，它还适用于Windows和MAC操作系统。借助此应用程序，您可以摆脱各种类型的垃圾文件。它还有助于提高设备的性能。该应用程序最有趣的功能之一是它允许您监控设备的温度。
3. Files by Google： Files by Google是一个文件管理器应用程序，界面简单，非常易于使用。它可以帮助您识别占用空间的垃圾文件，例如未使用的应用程序、媒体文件、缓存文件等。根据定义，它可能不是一个更干净的应用程序，但可以完成工作。
方法四：擦除缓存分区(Method 4: Wipe Cache Partition)
另一种删除缓存文件有点复杂的方法是擦除缓存分区。为此，您需要从引导加载程序将手机设置为恢复模式。这种方法存在一定的风险，不适合业余爱好者。您可能会对自己造成损坏，因此我们建议您仅在有一定经验的情况下才继续使用此方法，尤其是在植根Android手机方面。您可以按照下面给出的步骤擦除缓存分区，但请记住，确切的过程可能因设备而异。阅读有关您的设备以及如何在互联网上擦除其中的缓存分区的信息是一个好主意。
1. 第一件事就是关掉你的手机(switch off your mobile phone)。
2. 为了进入引导加载程序，您需要按下组合键。对于某些设备，它是电源按钮和降低音量键，而对于其他设备，它是电源按钮和两个音量键。
3. 请注意，触摸屏在引导加载程序模式下不起作用，因此当它开始使用音量键滚动选项列表时。
4. 转到恢复(Recovery)选项，然后按电源按钮将其选中。
5. 现在遍历到擦除缓存分区(Wipe cache partition)选项并按电源按钮将其选中。
6.删除缓存文件后，重新启动设备(reboot your device)。
您需要记住的一件事是，通过上述任何方法删除缓存文件都不会永久释放空间。下次打开应用时会自动生成新的缓存文件。(New)

How to Clear Cache on Android Phone (And Why Is It Important)
You must have noticed that thеrе is a certаin ѕection of your phone’s storage space that is occupied by cache fileѕ. Ενery aрp installed on your device cоntributes to the number of cache files. It might not seem a lot initially but as the number of apps keeps increasing on your device, theѕe cache filеs begіn to ocсupу a considerable amount of memory; the memory that could have beеn used to store personаl fileѕ like photos and vidеos.
The good news is that you can reclaim this space if you want to. Clearing cache files to free up storage is not only an efficient idea but also becomes necessary if your phone is old and running out of storage space. In this article, we are going to explain what are cache files and whether or not you should get rid of them.
How to Clear Cache on Android Phone (And Why Is It Important)
What is Cache?
The cache is nothing but some temporary data files. As mentioned earlier, every app that you use generates some cache files. These files are used to save different kinds of information and data. This data could be in the form of images, text files, lines of code, and also other media files. The nature of data stored in these files differs from app to app. They are also app-specific which means that one app’s cache files are useless for the other. These files are automatically created and stored securely in reserved memory space.
What is the function of Cache Files?
Apps generate cache files to reduce their loading/startup time. Some basic data is saved so that when opened, the app can display something quickly. For example, your browser saves its home page as a cache file to quickly load when opened. A game might save log-in data so that you don’t need to enter login credentials every time and thus save time. A music player might save your playlists so that it does not have to refresh and reload the entire song database at the time of opening. This way cache files serve an important purpose to mitigate the waiting time for us to use an app. These cache files are dynamic and keep getting updated. Old files are replaced by new files. Data stored in these cache files changes with changes in the app or personal settings.
Why should you delete Cache Files?
Normally, there isn’t any need to manually delete cache files. As mentioned earlier, these cache files are dynamic and automatically get deleted after some time. New cache files are generated by the app which takes its place. However, on certain occasions, it becomes necessary to clear the cache files. Let us now take a look at these situations:
1. Cache files are saved by apps to accelerate their loading time. However, sometimes these cache files get corrupted and interfere with the normal functioning of the app. Corrupted cache files can cause the app to malfunction, lag or even crash. If some app is not working properly, then you should clear its cache files to fix the error.
2. These files also consume a considerable amount of space. Especially browsers and social media apps save a lot of data as cache files and this occupies a lot of memory. In order to free up space, it is necessary to clear old cache files from time to time. This is, however, a temporary solution as the app would generate new cache files the next time you open the app.
3. Some apps save private and sensitive information like your log in credentials or search history in cache files. This poses a security threat. If anyone else is able to get their hands on these cache files, then your privacy is compromised. They can even use your identity to commit malpractices and the blame would fall on you. Therefore, another reason to clear cache files on Android is to avoid security threats.
4. Finally, if you find your app (say Instagram or browser) stuck on the same feed and would not refresh and load fresh posts, then clearing the cache files will force the app to reload and display fresh content.
4 Ways to Clear Cache on Android Phone
There are multiple ways to clear the cache on Android devices. You can either clear cache files for individual apps or for all the apps in one go. If you don’t want to delete these files manually, then you can also opt for a third-party app to do your bidding. In this section, we will be discussing the various methods in detail and provide you with a step by step guide to clear cache files.
Method 1: Clear all Cache Files
Android system allows you to get rid of cache files for all the apps in one go. This not only saves time and effort but clears up a lot of space instantaneously. Despite being easy and convenient, this method is seldom used as it is counter-productive. If you delete all the cache files at one go, then you would have to log in to every app when you open them next time. In fact, the new Android versions, i.e. Android 8 (Oreo) and above have done away with the option to delete all cache files in one go. If you are using an older Android device and would like to clear all cache files, then follow the steps given below:
1. Open Settings on your phone.
2. Now tap on the Storage and memory option.
3. Here, you will find an analytical report of how much memory is being occupied by various kinds of files and apps.
4. Scroll down and tap on the Cached data option.
5. A pop-up message will now be displayed on your screen asking you whether or not you would like to clear cached data for all apps. Click on the yes button.
6. Doing so will clear all the cache files from your device.

Method 2: Delete Cache files for Individual Apps
This is the more common and usual method to clear cache files. If a particular app is crashing or not working properly, you need to delete the cache files for just that app. Apart from that, if the main objective is to free up space, then simply select the apps consuming more space (usually browsers and social media apps) and delete the cache files for them. Follow the steps given below to learn how to delete or clear cache files for an individual app on your Android phone:
1. Go to the Settings on your phone.
2. Click on the Apps option to view the list of installed apps on your device.
3. Now select the app whose cache files you would like to delete and tap on it.
4. Click on the Storage option.
5. Here, you will find the option to Clear Cache and Clear Data. Click on the respective buttons and the cache files for that app will get deleted.
Method 3: Clear Cache using a Third-Party App
Another effective way to clear cache is by using a third-party app. There are a lot of cleaning apps available on the Play Store that will not only help you to clear cache files but other junk files as well. These are apps are a great means to free up memory and also boost your RAM. Some of the best apps available in the market are:
1. Clean Master: This is one of the most popular cleaner apps on Play Store and has over a billion downloads to its name. Clean Master allows you to clear cache files, system junk, unused app data, duplicate files, etc. It also clears background processes to free up RAM. Apart from that, Clean Master has a battery saver utility and also an antivirus system.
2. CC Cleaner: Another useful app that you can try is the CC Cleaner. Apart from Android, it is also available for Windows and MAC operating systems. With the help of this app, you can get rid of various types of junk files. It also helps improve the performance of the device. One of the most interesting features of the app is that it allows you to monitor the temperature of the device.
3. Files by Google: Files by Google is a file manager app with a simple interface and is very easy to use. It helps you to identify junk files that are consuming space like unused apps, media files, cache files, etc. It might not be a cleaner app by definition but gets the work done.
Method 4: Wipe Cache Partition
Another method to delete cache files which is a little complicated is by wiping the cache partition. In order to do this, you need to set the phone in recovery mode from the bootloader. There is a certain amount of risk associated with this method and it is not for an amateur. You might cause damage to your own and so we recommend you to proceed with this method only if you have some experience, especially in rooting an Android phone. You can follow the steps given below to wipe cache partition but keep in mind that the exact procedure may differ from device to device. It would be a good idea to read about your device and how to wipe cache partition in it on the internet.
1. The first thing that you need to do is to switch off your mobile phone.
2. In order to enter the bootloader, you need to press a combination of keys. For some devices, it is the power button along with the volume down key while for others it is the power button along with both the volume keys.
3. Take note that the touchscreen does not work in the bootloader mode so when it starts using the volume keys to scroll through the list of options.
4. Traverse to the Recovery option and press the power button to select it.
5. Now traverse to the Wipe cache partition option and press the power button to select it.
6. Once the cache files get deleted, reboot your device.
One thing that you need to keep in mind is that deleting cache files by any of the methods described above does not permanently free up space. New cache files will be automatically generated the next time you open the app.
