如何在 Windows 10 中显示文件扩展名： ^{(How to Show File Extensions in Windows 10: )}文件扩展^{(File Extension)}名是文件的结尾，有助于识别Windows 10中的文件类型。例如，文件名“example.pdf”具有文件扩展名“.pdf”，这意味着该文件与 adobe acrobat reader 相关联，并且是 pdf 文件。现在，如果您是Windows新手用户，那么查看文件扩展名以识别您尝试打开的文件类型非常重要。

但首先，您应该知道为什么文件扩展名很重要，这很重要，因为您甚至可以在不知情的情况下点击恶意软件/病毒文件。例如，您下载了一个文件 security.pdf.exe，现在如果您隐藏了文件扩展名，您只会看到该文件为 security.pdf，这是一个很大的安全风险，因为您肯定会打开该文件，认为它是您的 pdf 文件. 该文件可能会损坏您的系统，这就是文件扩展名很重要的原因。

当文件扩展名被禁用时，您仍然会看到与该文件类型相关联的程序图标。例如，如果您有一个文件 test.docx，那么即使您禁用了文件扩展名，您仍然会在文件上看到Microsoft Word或默认程序图标，但扩展名“.docx”将被隐藏。

这并不意味着您不会被病毒或恶意软件欺骗，因为它们可以伪装您的文件类型的图标并且仍然是恶意程序或应用程序，因此在Windows中启用文件扩展名总是一个好主意。因此，不要浪费任何时间，让我们在下面列出的指南的帮助下看看如何在Windows 10中显示^{(Windows 10)}文件^(File) 扩展名。^(Extensions)

How to Show File Extensions in Windows 10

How to Show File Extensions in Windows 10: File Extension is ending of a file which helps in identification of the type of file in Windows 10. For example, the file name “example.pdf” has the file extension “.pdf” which means the file is associated with adobe acrobat reader and is a pdf file. Now if you are a novice Windows users then it’s very important to see file extension in order to identify the type of file you’re trying to open.

But first, you should know why file extensions are important, well, it’s important because you could click on malware/virus files without even knowing so. For example, you downloaded a file security.pdf.exe, now if you have file extension hidden you will only see the file as security.pdf which is a big security risk as you will definitely open the file thinking it of as your pdf file. This file could potentially damage your system and that is why file extensions are important.

When file extensions are disabled you would still see the icon of the program which is associated with that file type. For example, if you have a file test.docx, then even if you have file extension disable, you would still see the Microsoft Word or the default program icon on the file but the extension “.docx” would be hidden.

This doesn’t mean that you can’t be tricked by virus or malware because they can disguise the icon of your file type and still be a malicious program or application, so it always a good idea to enable file extensions in Windows.
