压缩文件可以节省Chromebook上的存储空间。压缩文件还提供了一种快速共享一组文件而不会丢失数据的方法。与Windows、macOS 和Linux一样，Chrome操作系统（Chrome OS）可以压缩和解压缩文件(zip and unzip files)。
本教程向您展示如何将文件和文件夹捆绑到Chromebook上的(Chromebook)ZIP文件中。您还将了解在ChromeOS中提取(ChromeOS)ZIP文件内容的不同方法。
如何在 Chromebook 上压缩文件
使用 ChromeOS 的文件管理器，您可以将不同的文件类型（图片、音频文件、视频等）捆绑到ZIP文件中。
- 打开Files应用程序（按Shift + Alt + M）并导航到包含要ZIP的文件的文件夹。
- 右键单击要压缩的文件，然后选择Zip selection。
ChromeOS将创建一个与原始文件同名
的ZIP文件。(ZIP)
- 您还可以将多个文件捆绑到一个ZIP文件中。按住Ctrl键并使用 Chromebook 的触控板或鼠标选择文件。
- 右键单击(Right-click)所选文件并选择Zip选择。
Chrome 操作系统(Chrome OS)会将所选内容压缩成一个名为“Archive.zip”的ZIP文件。(ZIP)要更改默认标题，请右键单击ZIP文件，选择重命名(Rename)，然后输入您的首选标题。或者，选择ZIP文件并按Ctrl + Enter以快速更改其标题。
如果压缩文件夹，生成的ZIP文件将与文件夹具有相同的名称/标题。也就是说，“Screenshots.zip”将是压缩“Screenshots”文件夹的结果文件。
如何对Chromebook上的(Chromebooks)ZIP 文件进行密码保护(ZIP Files)
ChromeOS 不支持ZIP 文件的加密(encryption of ZIP files)。您需要在Chromebook(Chromebook)上使用第三方应用程序来保护压缩文件的密码。RAR（来自 RARLAB）(RAR (from RARLAB))和ZArchiver等(ZArchiver)Android应用程序将完成这项工作。
这两个应用程序都是免费且易于使用的，但RAR（来自RARLAB）具有更好的界面。请按照以下步骤查看如何使用该应用在Chromebook上创建受密码保护的(Chromebook)ZIP文件。
- 从Google Playstore下载并安装RAR应用程序。打开应用程序并在出现提示时授予其访问文件的权限。
- 选中要压缩的文件或文件夹旁边的框。选择顶部菜单上的将文件添加(Add)到存档图标以继续。
- 选择ZIP文件格式并在对话框中输入ZIP文件的首选标题。选择浏览(Browse)按钮以更改目标文件夹。
- 接下来，选择设置密码(Set Password)按钮以加密ZIP文件。
- 在提供的对话框中输入密码，然后选择确定。
- 最后，在“存档选项”页面上选择确定，将受密码保护的ZIP文件保存在目标文件中。
检查文件(Files)应用程序中的目标文件夹并验证RAR是否成功创建了加密的ZIP文件。没有加密密码的任何人都无法在您的Chromebook和其他设备
上打开或提取ZIP文件的内容。
如何在 Chromebook 上解压缩文件
在Chromebook上提取(Chromebooks)ZIP文件有两种不同的方法。您可以使用 ChromeOS 的ZIP提取功能或手动复制ZIP文件的内容。
使用 ChromeOS 的解压功能解压文件
(Chromebooks)运行ChromeOS 101或更高版本的(ChromeOS 101)Chromebook可以直接提取archived/compressed ISO, TAR, and RAR files的内容。右键单击要解压缩的文件，然后在弹出菜单中选择全部
提取。(Extract)
ChromeOS会将(ChromeOS)ZIP文件的内容提取到与原始ZIP文件同名的文件夹中。如果您解压缩“Pictures.zip”文件，Chromebook会将内容提取到“Pictures”文件夹中。
如果您在右键单击压缩文件时在上下文菜单中没有找到“全部提取”选项，请
更新您的Chromebook 。
将您的 Chromebook 连接到 Wi-Fi 网络(Connect your Chromebook to a Wi-Fi network)，打开设置(Settings)，选择侧边栏上的关于ChromeOS，然后选择检查(Check)更新。选择重新启动以在您的(Select Restart)Chromebook上安装预下载的更新。
手动解压文件
此方法涉及将压缩文件的内容复制并粘贴到Chromebook上的不同文件夹中。
- 双击(Double-click)压缩(zipped)文件以访问其内容。或者，选择压缩(zipped)文件并选择顶部菜单栏上的
打开。(Open)
如果ZIP文件受密码保护，请输入加密密码并选择解锁(Unlock)。
- 选择并右键单击要提取的文件，然后在上下文菜单中
选择复制。(Copy)
- 前往您要提取文件的位置/文件夹，右键单击文件夹中的任意位置，然后选择粘贴(Paste)。
提示：使用Ctrl + C和Ctrl + VChromebook上快速复制和粘贴文件。
- ChromeOS将(ChromeOS)ZIP文件挂载并显示为侧边栏上的外部驱动器。提取其内容后
，选择ZIP文件旁边的弹出图标。(Eject)
享受无损压缩(Enjoy Lossless Compression)和提取(Extraction)
ChromeOS不会减少捆绑到单个压缩文件中的单个文件的大小或质量。在解压缩过程中也没有质量损失或尺寸减小。如果您在压缩和解压缩文件时遇到问题，请重新启动Chromebook或更新其操作系统。
How to Zip and Unzip Files on Your Chromebook
Compresѕing files cаn save storage spаce on уour Chromebook. Zipping files also offers a quick way to share a group of files without data loss. Like Wіndows, macOS, and Linux, the Chromе operating system (Chrome OS) can zip and unzip files.
This tutorial shows you how to bundle files and folders into ZIP files on your Chromebook. You’ll also learn different ways to extract the content of ZIP files in ChromeOS.
How to Zip Files on Chromebooks
Using ChromeOS’ file manager, you can bundle different file types (pictures, audio files, videos, etc.) into a ZIP file.
- Open the Files app (press Shift + Alt + M) and navigate to the folder containing the files you want to ZIP.
- Right-click the file you want to zip and select Zip selection.
ChromeOS will create a ZIP file with the same name as the original file.
- You can also bundle multiple files into a single ZIP file. Hold the Ctrl key and use your Chromebook’s trackpad or mouse to select the files.
- Right-click the selected files and select Zip selection.
Chrome OS will compress the selection into a ZIP file titled “Archive.zip.” To change the default title, right-click the ZIP file, select Rename, and enter your preferred title. Alternatively, select the ZIP file and press Ctrl + Enter to change its title quickly.
If you zip a folder, the generated ZIP file will have the same name/title as the folder. That is, “Screenshots.zip” will be the resulting file from zipping a “Screenshots” folder.
How to Password-Protect ZIP Files on Chromebooks
ChromeOS doesn’t support the encryption of ZIP files. You’ll need to use third-party apps to secure compressed files with a password on your Chromebook. Android apps like RAR (from RARLAB) and ZArchiver will do the job.
Both apps are free and easy to use, but RAR (from RARLAB) has a better interface. Follow the steps below to see how to use the app to create password-protected ZIP files on your Chromebook.
- Download and install the RAR app from the Google Playstore. Open the app and grant it permission to access your files when prompted.
- Check the boxes next to the files or folders you want to zip. Select the Add files to archive icon on the top menu to proceed.
- Select the ZIP file format and enter a preferred title for the ZIP file in the dialog box. Select the Browse button to change the destination folder.
- Next, select the Set Password button to encrypt the ZIP file.
- Enter a password in the provided dialog box and select OK.
- Finally, select OK on the “Archiving options” page to save the password-protected ZIP file in the destination file.
Check the destination folder in the Files app and verify that RAR successfully created the encrypted ZIP file. Anyone without the encryption password cannot open or extract the content of the ZIP file on your Chromebook and other devices.
How to Unzip Files on Chromebook
There are two different ways to extract ZIP files on Chromebooks. You can either use ChromeOS’ ZIP extraction feature or manually duplicate the content of the ZIP file.
Unzip Files Using ChromeOS’ Extraction Feature
Chromebooks running ChromeOS 101 or newer can directly extract the content of archived/compressed ISO, TAR, and RAR files. Right-click the file you want to unzip and select Extract all on the pop-up menu.
ChromeOS will extract the ZIP file’s content to a folder with a similar name as the original ZIP file. If you unzip a “Pictures.zip” file, your Chromebook extracts the content into a “Pictures” folder.
Update your Chromebook if you don’t find the “Extract all” option on the context menu when you right-click a zipped file.
Connect your Chromebook to a Wi-Fi network, open Settings, select About ChromeOS on the sidebar, and select Check for updates. Select Restart to install a pre-downloaded update on your Chromebook.
Unzip Files Manually
This method involves copying and pasting the content of a zipped file to a different folder on your Chromebook.
- Double-click the zipped file to access its content. Alternatively, select the zipped file and choose Open on the top menu bar.
If the ZIP file is password-protected, enter the encryption password and select Unlock.
- Select and right-click the file(s) you want to extract and select Copy on the context menu.
- Head to the location/folder you want to extract the files, right-click anywhere in the folder, and select Paste.
Tip: Use the Ctrl + C and Ctrl + V keyboard shortcuts to copy and paste files on your Chromebook quickly.
- ChromeOS mounts and displays the ZIP file as an external drive on the sidebar. Select the Eject icon next to the ZIP file after extracting its content.
Enjoy Lossless Compression and Extraction
ChromeOS doesn’t reduce the size or quality of individual files bundled into a single zipped file. There’s also no loss of quality or size reduction in the unzipping process. Restart your Chromebook or update its operating system if you’re experiencing issues zipping and unzipping files.
