Windows 中的常见文件扩展名 - Microsoft 支持
Windows 10 Windows 文件名包含由句点分隔的两个部分:第一部分是文件名,第二部分是定义文件类型的三字符扩展名或四字符扩展名。 例如,在“expenses.xlsx”中,文件名的第一部分是“expenses”,扩展名为“xlsx”。 扩展名告诉计算机哪个创建的应用程序或者哪个其他程序可以打开该文件以及用于该文件的图标。 例如,“docx”扩展名告诉计算机 Microsoft Word 可以打开该文件,并且当你在“文件资源管理器”中查看它时会告诉计算机显示 Word 图标。 大多数文件扩展名与你已安装的多个程序兼容。 你可以更改文件扩展名,但这不会将文件转换为其他格式,也不会更改除文件名之外的任何文件相关内容。
