随着时间的推移，删除手机或平板电脑上的临时文件几乎是必要的。您的设备出于特定原因使用文件，但在使用完文件后，它可能不会删除它们，这可能导致无响应、过度使用存储空间、内存问题等。
在安装和使用应用程序、执行设备更新和删除应用程序后会创建临时文件。在不知不觉中，有数百甚至数千个文件不再需要，如果留下，可能会导致许多问题。
幸运的是，有多种方法可以删除手机或平板电脑上的临时文件、应用程序缓存、剩余数据和其他未使用的文件。
提示：(Tip:)还有用于计算机的垃圾文件删除器，可以删除台式机或笔记本电脑上的临时文件。
使用清洁应用程序(Cleaning App)删除临时(Delete Temporary)文件
有如此多的应用程序专门用于清除手机或平板电脑上的垃圾文件，这一事实证明了它的必要性。
Android设备有多种垃圾文件清理选项，包括Google 自己的 Files 应用程序(Google’s own Files app)。在“文件”内有一个名为“清理(Clean)”的部分，它可以帮助释放您在消息传递应用程序中发送和接收但您可能不再需要的媒体文件——您会惊讶于那里可以收集到多少垃圾。
它还会删除其他垃圾文件，并帮助您找到可能要删除的未使用应用程序。
您还可以使用底部的浏览选项卡访问(Browse)下载(Downloads)部分。其中可能有一些文件在您下载它们时有目的但您不再需要它们。
去那里检查可能会占用不必要的空间的内容，并删除您不想要的内容。
以下是我们推荐的一些其他Android应用程序，用于删除垃圾文件、应用程序缓存、临时数据和其他不必要的内容：
- Clean Master：包括一个垃圾清理器，可删除残留文件，并作为一个Android 防病毒应用程序(Android antivirus app)保护您的设备免受恶意软件的侵害。
- 超级清理器(Super Cleaner)：清理无用的应用程序缓存文件，包括一个CPU冷却器，并让您将私人信息锁定在密码后面。
- 安全大师(Security Master)：多用途应用程序，可删除旧的APK文件、广告垃圾、缓存、空文件夹和通知项，还可以运行病毒扫描并使用密码锁定应用程序(locks apps behind a password)。
在 iPhone 和 iPad 上删除临时文件的工作方式略有不同，因为没有移动应用程序可以做到这一点。
要删除 iOS 设备上的垃圾文件，您可以使用计算机上的程序。只需(Just)将 iPhone 或 iPad 插入计算机并运行临时文件清理程序即可擦除数据。
PhoneClean（适用于Windows和Mac）是此类程序的一个示例。虽然某些功能不是免费的，但它始终适用于最新的 iOS 版本，并且在删除 iPad 和 iPhone 上的垃圾文件方面做得非常出色。
它具有非常酷的选项，例如可以每天无线自动清除垃圾的静音清洁功能，以及快速清洁、互联网清洁、隐私清洁、系统清洁、应用清洁和联系人清洁等功能。
例如，快速清理功能将删除多余的系统和用户日志、过时的临时文件和照片缓存，还会向您显示可以删除以释放空间的大文件和旧文件。
一个类似的 iPhone 和 iPad 垃圾清理器是iFreeUp，它可以删除缓存和垃圾数据，但也可以用作文件传输工具、应用程序数据导出器和 iOS 系统优化器。
手动删除应用缓存
几乎您使用的每个应用程序都维护着一组供离线使用的文件，这有助于加快您对应用程序各个部分的访问。例如，图像和网页可能由您的 Web 浏览器存储，这样您就可以快速重新打开这些文件，而无需在每次打开这些网页时从 Internet 获取它们。
但是，正如您猜想的那样，这些缓存文件可能会占用大量空间并影响您下载新文件和更新应用程序的能力。使用该应用程序时，缓存的文件甚至可能被损坏并导致问题。
大多数用于手机/平板电脑的垃圾文件清理器都具有清空缓存的功能。但是，如果您(can’t)不想仅仅为了删除应用缓存而下载新应用，或者因为空间不足而无法下载，请按照以下步骤了解如何手动删除应用存储的垃圾文件：
在安卓上(On Android)：
- 打开设置。
- 点按应用程序和通知(Apps & notifications)。
- 选择See all <#> apps。
- 从列表中找到最大的应用程序，或者您怀疑被额外垃圾文件超载的应用程序。
- 选择存储和缓存(Storage & cache)。
- 选择清除缓存(Clear cache )以立即清空该应用程序的缓存。
在 iOS 上(On iOS)：
iPhone 和 iPad 的系统设置中都没有用于清除应用程序缓存的部分，但某些应用程序确实在它们自己的设置中提供了该选项。
例如，在MEGA 在线文件存储应用程序(MEGA online file storage app)中，您进入设置(Settings )>文件管理(File Management )>清除缓存(Clear Cache)以刷新应用程序的缓存。大多数网络浏览器也提供缓存清理功能，通常在设置的隐私区域中，并且通常与(Privacy)清除浏览数据(Clear browsing data)屏幕 中的其他清理工具捆绑在一起。
检查您的屏幕截图文件夹
根据您使用手机或平板电脑的方式，屏幕截图可能会被您视为垃圾。如果您截取大量屏幕截图与他人共享或临时使用，但之后再也不打开它们，您应该知道它们仍在您的设备上占用了不必要的空间。
如果您不想将屏幕截图备份到在线文件存储服务，您可以快速删除它们。
在 Android 上，打开照片(Photos)应用程序，点击左上角的三行菜单，然后转到设备文件夹(Device folders)>屏幕截图(Screenshots )以查看其中的内容。选择(Select)并删除您不想立即清理这些垃圾文件的所有内容。
如果您使用的是 iOS 设备，请前往照片(Photos)>相册(Albums )>屏幕截图(Screenshots)以选择要从 iPhone 或 iPad 中删除的屏幕截图。您可以使用“选择(Select)”按钮一次删除多个屏幕截图，或者将设备插入计算机以轻松批量删除图像。
How To Delete Temporary Files & Other Junk On a Smartphone or Tablet
Deleting tеmporary files on your phone or tablet is almoѕt a necessity as time gоes on. Your deνice uses files for a specifіc reason, but then when it’s done with them, it might not remove them, which can lead to unresponsively, excess storagе usage, memory рroblems, etc.
Temporary files are created after apps
are installed and used, device updates are performed, and apps are
removed. Before you know it, there are hundreds or even thousands of
files that are no longer needed and that if left, can cause a host of
problems.
Fortunately, there are several ways to
delete temporary files, app caches, leftover data, and other unused
files on your phone or tablet.
Tip: There are also junk file removers for computers that will delete temporary files on your desktop or laptop.
Use a Cleaning App To Delete Temporary Files
The fact that there are so many apps
dedicated to cleaning junk files off a phone or tablet is evidence
that there’s a need for it.
There are several junk file cleaning options for Android devices, including Google’s own Files app. Within Files is a section called Clean that can help free up media files you’ve sent and received within messaging apps but that you probably don’t want anymore – you’d be surprised how much junk can be collected there.
It also deletes other junk files and helps you locate unused apps that you might want to delete.
You can also use the Browse tab at the bottom to access the Downloads section. In there might be files that had a purpose when you downloaded them but that you no longer need.
Go in there to check out what might be using up unnecessary space, and delete whatever you don’t want.
Here are some other Android apps we
recommend for deleting junk files, app caches, temporary data, and
other unnecessary:
- Clean Master: Includes a junk cleaner that removes residual files and functions as an Android antivirus app that protects your device from malware.
- Super Cleaner: Cleans useless application cache files, includes a CPU cooler, and lets you lock private information behind a password.
- Security Master: Multi-purpose app that deletes old APK files, ad junk, caches, empty folders, and notification items, but also runs virus scans and locks apps behind a password.
Deleting temporary files on iPhone and iPad works a little differently since there aren’t mobile apps that can do it.
To remove junk files on your iOS device, you can use a program on your computer. Just plug in your iPhone or iPad to your computer and run the temp files cleaner to erase the data.
PhoneClean (for Windows and Mac) is one example of such a program. While some of the features aren’t free, it always works with the newest iOS version and does a phenomenal job at deleting junk files on both iPad and iPhone.
It features really cool options like a silent clean function that can clear junk wirelessly and automatically every day plus a quick clean, internet clean, privacy clean, system clean, app clean, and contact clean feature, among others.
The quick clean function, for instance,
will remove redundant system and user logs, outdated temporary files,
and photo caches, and will also show you large and old files that you
could delete to free up space.
A similar junk cleaners for iPhone and iPad is iFreeUp, which deletes caches and junk data but also functions as a file transfer tool, app data exporter, and iOS system optimizer.
Manually Delete App Caches
Almost every app you use maintains a collection of files for offline use that helps speed up your access to the various parts of the app. Images and webpages might be stored by your web browser, for example, so that you can reopen those files quickly without fetching them from the internet each time you open those webpages.
However, as you’d guess, these cached
files can take up loads of space and affect your ability to download
new files and update apps. The cached files can even be corrupted and
cause issues when using the app.
Most junk file cleaners for your
phone/tablet include the ability to empty the cache. However, if you
don’t want to download a new app just to delete app caches, or if
you can’t because you don’t have enough room, follow these
steps to learn how to manually remove junk files stored by your apps:
On Android:
- Open Settings.
- Tap Apps & notifications.
- Select See all <#> apps.
- Locate the biggest apps from the list, or apps that you suspect are overloaded with extra junk files.
- Select Storage & cache.
- Choose Clear cache to immediately empty that app’s cache.
On iOS:
Neither iPhone nor iPad has a section
in the system settings for clearing app caches, but some apps do
provide the option in their own settings.
For example, in the MEGA online file storage app, you go into Settings > File Management > Clear Cache to flush the app’s cache. Most web browsers provide a cache cleaning function, too, usually in a Privacy area of the settings and often bundled with other cleaning tools in a Clear browsing data screen.
Check Your Screenshots Folder
Depending on how you use your phone or
tablet, screenshots might be considered junk to you. If you take lots
of screenshots to share with others or to use temporarily, but then
never open them again, you should be aware that they’re still on
your device taking up unnecessary space.
If you don’t want to back up your screenshots to an online file storage service, you can quickly delete them.
On Android, open the Photos app, tap the three-lined menu at the top left, and go to Device folders > Screenshots to see what’s there. Select and delete everything you don’t want to instantly clean up those junk files.
If you’re using an iOS device, go to Photos > Albums > Screenshots to choose which screenshots to delete from your iPhone or iPad. You can use the Select button to remove more than one screenshot at once, or plug your device into your computer to easily delete the images in bulk.
