常见的文件头格式
常见的文件头格式文件头格式，也称为文件标记或文件签名，是一种用于标识文件类型的数据结构。
在计算机科学中，不同的文件类型由不同的文件头格式来标识。
常见的文件头格式有许多种，下面是一些常见类型的文件头格式：1. 文本文件：UTF-8：通常以 EF BB BF 开头。
UTF-8 是一种可变长度字符编码，用于表示 Unicode 字符。
UTF-16：通常以 FE FF 开头。
UTF-16 是一种 Unicode 字符编码。
ISO-8859-1：也称为 Latin-1，通常以 00 开头。
它是一种用于西欧语言的字符编码。
2. 图片文件：JPEG：以 FF D8 FF 开头。
JPEG 是一种常见的图像文件格式。
PNG：以 89 50 4E 47 0D 0A 1A 0A 开头。
PNG 是一种无损压缩的位图图形格式。
GIF：以 47 49 46 38 或 47 49 46 39 开头。
GIF 是一种基于 LZW 算法的连续色调无损压缩格式。
3. 音频文件：MP3：不同的编码可能有所不同，但常见的以 FF FB 开头。
MP3 是一种音频压缩格式。
WAV：通常以 52 49 46 46 开头。
WAV 是 Windows 操作系统下的音频文件格式。
4. 视频文件：AVI：通常以 52 49 46 46 开头。
AVI 是 Microsoft 开发的音频视频交错格式。
MP4：以 66 FF FF 或 00 FF FF 开头。
MP4 是一种音频和视频封装格式，常用于数字媒体播放。
5. 压缩文件：ZIP：以 50 4B 03 04 或 50 4B 05 06 开头。
ZIP 是用于数据压缩的归档文件格式。
RAR：以 52 61 72 开头。
RAR 是用于数据压缩的归档文件格式，由 WinRAR 公司开发。
6. 可执行文件：PE (Windows 可执行文件)：通常以 4D 5A 开头。
PE 是 Microsoft Windows 可执行文件的格式。
两个文件,三大标志
两个文件，三大标志概述在计算机系统中，每个文件都具有文件属性，而在文件属性中又包含了很多标志，它们能够指示文件的种类、状态、权限等信息，从而使得文件能够更加方便地被处理和管理。
本文将会介绍两个常见的文件类型——文本文件和二进制文件，并讨论它们各自的三个关键标志。
文本文件文本文件是一种基本的文件类型，保存的是文本内容，以纯文本的形式存储，通常采用 ASCII 或 Unicode 编码。
由于文本文件内容仅由字符和换行符组成，所以文本文件的处理也相对比较简单，可以直接使用文本编辑器进行编辑、查看和修改。
标志一：文件编码文件编码是文本文件最重要的标志之一，它指示了文本文件中字符所采用的编码方式。
一般来说，文本文件可以采用多种不同的编码方式，比如 ASCII、UTF-8、GBK 等。
不同的编码方式对应的字符集以及字符数量也都不相同，因此在处理文本文件时，必须要清楚文件所采用的编码方式，否则就会导致乱码等问题。
标志二：文件格式文件格式指示了文本文件中行尾符的类型。
通常情况下，不同的操作系统所采用的行尾符是不一样的，比如 Windows 采用的是回车符（\\r）和换行符（\）的组合（即\\r\），而 Linux 和 macOS 均采用换行符（\）。
因此，文件的格式也需要指示清楚，否则就会导致跨操作系统使用文件时出现问题。
标志三：文件结尾不同的操作系统对文件结尾的处理也是不一样的。
在 Windows 系统中，每个文本文件的结尾都要有一个特殊的字符组合（即\\r\），以表示文件的结尾；而在 Linux 和 macOS 中，则不需要这个特殊的字符组合。
因此，当在不同的操作系统之间传递文件时，就需要留心文件结尾标志的问题。
二进制文件与文本文件不同，二进制文件是以二进制形式保存的文件类型，它表示的是一组字节码，没有固定的字符集和编码方式。
因此，处理二进制文件的难度要高于处理文本文件，需要使用专用的工具才能逐个字节地读取和编辑二进制文件。
