推荐答案

究竟是什么让你认为你可以查看数据并自动识别它从前几个字节作为特定的文件类型：没有十六进制签名将唯一标识文件类型 - 这就是我们有扩展名的原因。如果我们有一个十六进制签名，我们就不需要扩展名......



例如：.BAK用于很多系统的工作原始数据的副本，因此理论上它可以包含任何类型的文件。 .CSV看起来很像一个正常的文本文件，直到你尝试解析它并发现它有点像垃圾数据一样垃圾。



使用扩展：这就是它的用途！

What on earth makes you assume that you can look at data and automatically identify it from the first couple of bytes as being a particular file type: there is no "hex signature" that will uniquely identify a file type - that's why we have the extension. If we had a hex signature, we wouldn't need the extension...

For example: .BAK is used for a heck of a lot of systems as a copy of the original data, so it could contain any type of file in theory. .CSV will look a lot like a "normal" text file, until you try to parse it and find it's a bit, well, rubbish as CSV data.

Use the extension: that's what it's there for!
