| 摘 要： | 不同类型文件的识别与匹配是计算机文件系统中一个重要问题,一般分为特征标识(魔数)和后缀名两种方式,其中后者是被广泛接受的一种方式.然而在使用过程中,经常遇见文件名被篡改或损坏、文件后缀名缺失而无法被系统自动识别的情况,此时无法正常打开、浏览或编辑文件.文件头的特征标识将文件特征信息存储于文件数据内部,不容易被修改或损坏...

| Abstract: | File type recognizing and matching is an essential element in computer file systems.It is always implemented in two methods: identifier(magic number) and postfix.The method based on postfix is more commonly used.But sometimes file names are changed and destroyed,and postfixes are absent,so these files can't be recognized or opened or edited.Identifier which is attached by file information is stored in file data body.It is defined uniquely and can't be modified or destroyed easily,so it can be used as a foun... |
