存在数千种不同类型的文件(different types of files)，分为音乐或文档文件等类别，但每种都有自己的功能和限制。例如，MP3文件可能非常适合音频，但AAC文件更好。然而，没有任何真正竞争的一种格式是 .MSG 文件格式。
如果你看到一个 . MSG文件，那么您可能正在使用Microsoft Outlook，因为Outlook使用MSG文件来导出电子邮件和其他任务。如果您没有Windows上的Outlook，或者您使用的是Mac上的Outlook，那么您可能无法打开它。要在Windows(Windows)或Mac上打开MSG文件，您需要执行以下操作。
什么是味精文件，它安全吗？
MSG文件格式特定于Microsoft Outlook，它使用MSG文件将不同类型的内容导出到Outlook本身之外。通常，MSG文件将包含从其他用户收到的电子邮件，但也可以包含日历约会、任务和其他Outlook项目。
MSG文件包含用于其目的的相关信息。对于电子邮件，这可能包括发件人和收件人、收到电子邮件的时间和日期、主题和邮件正文。如果您要保存日历约会，MSG文件可能包含日期、位置和其他受邀用户。
MSG文件在(MSG)Outlook本身中创建时无害。打开您自己创建的MSG文件是没有风险的，但您应该对打开来自您不信任的来源的文件保持警惕。虽然不太可能，但像MSG文件格式这样的格式可以与恶意软件一起打包。
对于带有附件的导出电子邮件尤其如此。由于您无法在不打开MSG文件的情况下判断附件，因此您可能会将您的 PC 置于危险之中。如果是这种情况（并且您打开了一个您不信任的文件），那么您需要扫描恶意软件(scan for malware)以防万一。
如何在 Windows 上打开 MSG 文件
MSG文件格式是基于Outlook的，因此在Windows上打开它通常需要Outlook桌面应用程序。
- 如果在您的 PC 上安装并设置了Outlook ，则(Outlook)MSG文件格式应该已经与Outlook相关联。要打开MSG文件，请在桌面或(MSG)Windows 文件资源管理器(Windows File Explorer)中双击该文件。如果Outlook未自动与MSG文件关联，请右键单击该文件并选择打开(Open With)方式。
- 您也可以手动将MSG文件复制到Outlook收件箱中。(Outlook)为此，请右键单击桌面（或Windows 文件资源管理器）上的(Windows File Explorer)MSG文件，然后选择复制(Copy)。
- 在Outlook窗口（和您的Outlook收件箱）可见且处于活动状态时，按Ctrl + V 将MSG文件粘贴到您的收件箱中。然后，您现在可以查看邮箱中的邮件。
如果您没有安装Outlook，您可以使用第三方替代品，例如FreeViewer MSG Viewer。虽然界面有点过时，但 FreeViewer MSG Viewer应该可以让您安全地查看(FreeViewer MSG Viewer)Windows 10中任何导出的MSG文件的内容。
- 首先，在您的 PC 上下载并安装FreeViewer MSG Viewer应用程序。(FreeViewer MSG Viewer)在FreeViewer MSG Viewer窗口中，在左侧菜单中选择包含MSG文件的文件夹。(MSG)找到的任何MSG文件都将显示在右侧菜单中。
- 要打开一个MSG文件，请在FreeViewer MSG 查看器(FreeViewer MSG Viewer)列表中选择它。文件的内容，包括任何附件和隐藏的标题数据，将在底部可见。
虽然Outlook和(Outlook)FreeViewer MSG Viewer等第三方替代品效果最佳，但您也可以使用Encryptomatic MSG Viewer等在线 Web 服务来查看MSG文件中的数据，而无需其他软件。
但是，您应该只对非敏感文件或电子邮件执行此操作，因为将MSG文件上传到您不知道的服务器会将您的个人数据暴露给该网站，包括您的电子邮件地址和其他消息。
如何在 Mac 上打开味精文件
与Windows一样，macOS 支持完整的Microsoft Outlook客户端，可作为独立应用程序或作为Office套件的一部分提供。不幸的是，Mac版本的Outlook不允许您打开或导出MSG文件。
要在Mac(Mac)上打开MSG文件，您需要从App Store安装第三方MSG查看器（或使用在线服务，如上所述）。虽然存在各种应用程序，但最容易使用的应用程序之一是MSG Viewer for Outlook。这个应用程序通过将MSG文件转换为开源EML格式来工作。
- 首先，从App Store下载并安装(App Store)MSG Viewer for Outlook应用程序。安装后，从Launchpad 启动(Launchpad)应用程序。
- 打开MSG Viewer for Outlook应用程序后，您可以在“(Outlook)打开文件”(Opening Files)部分选择要打开的客户端或通讯簿应用程序。如果您想快速查看文件，请选择快速查看(Quick View)，或选择其中一个转换选项（例如，转换为 PDF(Convert to PDF)）将文件转换为另一种格式。设置完成后，从菜单栏中选择File > Open
- 在Finder窗口中，找到并选择您的MSG文件，然后选择打开(Open)按钮。这将开始从MSG到开源EML格式的转换过程。
- Outlook应用程序的MSG 查看器(MSG Viewer)将转换文件。完成后，您在“打开文件”(Opening Files)部分中选择的邮件应用程序将自动打开，允许您查看文件。
打开 Microsoft 文件格式
MSG文件格式，如DOCX和(DOCX)PPTX ，(PPTX)是专有的Microsoft文件格式。如果您在野外发现它们，那么您很可能需要Microsoft软件（或访问Microsoft服务）才能打开它们。如果您无法访问Outlook，您可以使用Encryptomatic Viewer等在线服务来打开您的MSG文件。
虽然Office是打开Office文档文件的最佳套件，但还有其他选择。LibreOffice和OpenOffice等开源软件(Open-source software)可以处理多种Office格式，允许您将文件转换为其他开源格式。如果您不想麻烦，可以改用Google Docs等在线服务。
What Is a .MSG File and How to Open It on Windows and Mac
There arе thouѕands of different types of files that exist, split into categories like music or document files, but each with their own function and limitations. For instance, an MP3 file might be great for audio, but an AAC file is even better. One format that doesn’t have any real competition, however, is the .MSG file format.
If you see an .MSG file, then you’re probably using Microsoft Outlook, as Outlook uses MSG files for exporting emails and other tasks. If you don’t have Outlook on Windows, or if you’re using Outlook on Mac, then you might not be able to open it. To open a MSG file on Windows or Mac, here’s what you’ll need to do.
What is a MSG File and Is It Safe?
The MSG file format is specific to Microsoft Outlook, which uses MSG files for exporting different types of content outside of Outlook itself. Usually, MSG files will contain email messages received from other users, but it can also include calendar appointments, tasks, and other Outlook items.
MSG files contain relevant information for its purpose. For emails, this might include the sender and recipient, the time and date the email was received, the subject, and the body of the message. If you’re saving calendar appointments, an MSG file may contain the date, location, and other invited users.
MSG files are not harmful when created in Outlook itself. Opening an MSG file you’ve created yourself is risk free, but you should remain vigilant about opening files from sources you don’t trust. While unlikely, formats like the MSG file format can be packaged with malware.
This is especially true for exported emails with included attachments. As you can’t judge the attachments without opening the MSG file, you could put your PC at risk. If that’s the case (and you open a file you don’t trust), then you’ll need to scan for malware as a precaution.
How to Open MSG Files on Windows
The MSG file format is Outlook-based, so opening it on Windows usually requires the Outlook desktop app.
- If Outlook is installed and set up on your PC, then the MSG file format should already be associated with Outlook. To open an MSG file, double-click the file on your desktop or in Windows File Explorer. If Outlook isn’t associated with MSG files automatically, right-click the file and select Open With instead.
- You can also copy MSG files into your Outlook inbox manually. To do this, right-click the MSG file on your desktop (or in Windows File Explorer), then select Copy.
- With the Outlook window (and your Outlook inbox) visible and active, press Ctrl + V to paste the MSG file into your inbox. You can then view the message in your mailbox now.
If you don’t have Outlook installed, you can use a third-party alternative like FreeViewer MSG Viewer instead. While the interface is a little outdated, FreeViewer MSG Viewer should let you safely view the contents of any exported MSG files in Windows 10.
- To begin, download and install the FreeViewer MSG Viewer app on your PC. In the FreeViewer MSG Viewer window, select the folders containing MSG files in the left-hand menu. Any MSG files that are found will appear in the right-hand menu.
- To open an MSG file, select it in the FreeViewer MSG Viewer list. The contents of the file, including any attachments and hidden header data, will become visible at the bottom.
While Outlook and third-party alternatives like FreeViewer MSG Viewer work best, you can also use online web services like Encryptomatic MSG Viewer to view the data from MSG files without additional software.
However, you should only do this for non-sensitive files or emails, as uploading MSG files to a server you don’t know will expose your personal data to that website, including your email address and other messages.
How to Open MSG Files on Mac
Like Windows, macOS supports the full Microsoft Outlook client, available as a standalone app or as part of the Office suite. Unfortunately, the Mac version of Outlook doesn’t allow you to open or export MSG files.
To open MSG files on Mac, you’ll need to install a third-party MSG viewer from the App Store (or use an online service, as described above). While various apps exist, one of the easiest to use is MSG Viewer for Outlook. This app works by converting MSG files into the open-source EML format instead.
- To start, download and install the MSG Viewer for Outlook app from the App Store. Once installed, launch the app from the Launchpad.
- With the MSG Viewer for Outlook app open, you can select the client or address book app you want to open in the Opening Files section. If you want to quickly view the file, select Quick View, or select one of the conversion options (eg. Convert to PDF) to convert the file to another format. Once your settings are in place, select File > Open from the menu bar.
- In the Finder window, find and select your MSG file, then select the Open button. This will begin the conversion process from MSG to the open-source EML format.
- The MSG Viewer for Outlook app will convert the file. Once this is complete, the mail app you selected in the Opening Files section will open automatically, allowing you to view the file.
Opening Microsoft File Formats
The MSG file format, like DOCX and PPTX, are proprietary Microsoft file formats. If you spot them in the wild, then it’s quite likely you’ll need Microsoft software (or access to Microsoft services) to open them. If you don’t have access to Outlook, you can use an online service like Encryptomatic Viewer to open your MSG files instead.
While Office is the best suite for opening Office document files, there are alternatives. Open-source software like LibreOffice and OpenOffice can handle many Office formats, allowing you to convert the files to other open-source formats. If you don’t want the hassle, you can switch to an online service like Google Docs instead.
