If your Android phone doesn’t have a lot of storage space, it can be a constant struggle to remove old junk and make room for new pictures, videos, and apps. Google’s Files app has a handy tool to make this process easy.
如果您的Android手机没有足够的存储空间，则可能会一直努力消除旧的垃圾并为新的图片，视频和应用腾出空间。 Google的“文件”应用程序提供了方便的工具，可简化此过程。
Files by Google is preinstalled on some Android phones, but anyone can download it from the Play Store. One handy feature that sets it apart from other file managers is its cleaning recommendations. It identifies things that can be removed from your phone to free up storage space.
Google的文件已预先安装在某些Android手机上，但任何人都可以从Play商店下载。 与其他文件管理器不同的一项方便功能是它的清理建议。 它标识可以从手机中删除的东西，以释放存储空间。
To get started, download and install Files by Google on your Android phone or tablet.
首先，请在您的Android手机或平板电脑上下载并安装Google提供的文件 。
If this is your first time using Files by Google, you’ll be asked to agree to Google’s Terms of Service and Privacy Policy. Tap “Continue” to proceed if you agree.
如果这是您首次使用Google提供的文件，则系统会要求您同意Google的服务条款和隐私权政策。 如果您同意，请点击“继续”继续。
To allow the Files app to access your files, tap “Allow” in the permissions popup.
要允许“文件”应用访问您的文件，请在权限弹出窗口中点击“允许”。
With that out of the way, you can start freeing up storage space. Tap “Clean” at the bottom.
这样一来，您就可以开始释放存储空间。 点击底部的“清洁”。
At the top of the page, you’ll see how much storage space you’re using. Underneath, Google will automatically suggest files you can delete to free up storage space. Common examples are screenshots, duplicate files, and photos that are already backed up to Google Photos.
在页面顶部，您将看到正在使用的存储空间。 在下面，Google会自动建议您可以删除的文件以释放存储空间。 常见的示例是屏幕快照，重复文件和已经备份到Google相册的照片。
Each of the following categories will have one of three possible buttons, and they perform slightly different actions:
以下每个类别将具有三个可能的按钮之一，并且它们执行的操作略有不同：
- “Confirm and Free Up (X) MB”: Where (X) is the amount of space. Tap this to open a popup and clean right away without reviewing the files first.
“确认并释放(X)MB”：其中(X)是空间量。 点击此按钮可打开弹出窗口并立即清除，而无需先检查文件。 - “Select and Free Up (X) MB”: Where (X) is the amount of space. Tap this to jump straight to the review screen, where you can select the files you want to remove.
“选择并释放(X)MB”：其中(X)是空间量。 点击此按钮可直接跳至查看屏幕，您可以在其中选择要删除的文件。 - “Free Up (X) MB”: Where (X) is the amount of space. This action is specifically for Google Photos. Google will suggest removing any photos on your device that have been backed up. Tap this to go to the Google Photos app, where you can choose to free up space.
“释放(X)MB”：其中(X)是空间量。 此操作专门用于Google相册。 Google建议您删除设备上已备份的所有照片。 点按此按钮可转到Google相册应用，您可以在其中选择释放空间。
For our example, we tap “Select and Free Up (X) MB” from the category we want to clean up.
对于我们的示例，我们从要清除的类别中点击“选择并释放(X)MB”。
We see a list of files Google suggests removing. In the “Duplicate Files” category, original files are indicated by a bookmark icon in the bottom left corner.
我们看到了Google建议删除的文件列表。 在“重复文件”类别中，原始文件由左下角的书签图标指示。
We select all the files we want to remove, and then tap “Delete.”
我们选择所有要删除的文件，然后点击“删除”。
If you select original files in the “Duplicate Files” category, you’ll be asked to confirm your choice; tap “Continue” to proceed.
如果您在“重复文件”类别中选择了原始文件，则系统会要求您确认选择； 点击“继续”继续。
You’ll be asked once again to confirm your choices. Tap “Delete” to permanently remove the files.
系统将再次要求您确认选择。 点击“删除”以永久删除文件。
If you want to clean up a category quickly, tap “Confirm and Free Up (X) MB” (where “X” is the amount of space) to skip selecting each file individually.
如果要快速清理类别，请点击“确认并释放(X)MB”(其中“ X”是空间量)以跳过单独选择每个文件的步骤。
Tap “Clean” to remove the files without reviewing them.
点击“清除”以删除文件而不查看它们。
To review files before removing them, tap “See Junk Files.”

A pop-up message will ask you to confirm your choice. Tap “Clear” to proceed.

That’s it! You can repeat these same steps for any of the categories on the “Clean” tab. The app might periodically recommend freeing up space, as well.
