常见文件头总结
- 2025-05-28 17:30:41
前言
我们都知道，文件的扩展名是用来识别文件类型的。通过给他指定扩展名，可以告诉操作系统我们想用什么方式打开这个文件。例如会把.jpg的文件默认用图片显示软件打开，.zip 文件会默认用解压软件打开等等。
然而，扩展名是可以随便改的，这样一来我们就不能了解到这个文件究竟是做什么的，究竟是个什么样的文件。那么为什么一个软件，比如视频播放器，就能用正确的方式打开.mp4，.rmvb，.wmv 等的文件类型呢？
文件头信息
所有的文件都是以二进制的形式进行存储的，本质上没有差别。之所以使用的方法不同，只是因为计算机理解他的方式不同。在每一个文件（包括图片，视频或其他的非ASCII文件）的开头（十六进制表示）实际上都有一片区域来显示这个文件的实际用法，这就是文件头标志。
在计算机中，文件头是一段用来描述文件内容和格式的数据。不同的文件格式有不同的文件头格式。文件头内容通常包含文件的类型、版本、编码方式、文件大小等信息，以方便计算机识别和处理文件。
Linux下我们可以用file命令直接查看文件的实际格式，其本质上也是利用文件头标志来进行文件类型判断的。
