<代码><>>>>/代码>的结果并不完美,在某些类型的档案中存在比其他类型更大的问题。 档案基本上只看看某些可预测模式的双元数据,以显示档案类型。

不幸的是,某些经常用于录像的档案类型属于这一“问题”。 新的集装箱格式,如.mp4.mkv。 通常有几个不同的监测和评价类型,应适当取决于所控制的数据类型。 例如,.mp4可适当确定为video/mp4,audio/mp4,或application/mp4,视内容而定。

实际上,file常常使热点简单地符合共同的用法,而且对你来说,会做得很好。 例如,虽然我提到在正确识别Matroska档案方面存在一些理论困难,但file基本上只是假定任何Matroska档案都是录像。 另一方面,Ogg集装箱的使用情况在音频和视频之间更为平衡,我认为目前版本的<代码>。 公正地区分差异,确定 页: 1

我可以肯定地说的是,你希望能掌握最新版本的<代码><>>>> /代码>。 含有配对模式的“魔法”档案以及由配对而产生的“监测和评价”类型,往往得到相当程度的更新,以包括诸如“网络”等新的档案类型,或只是为了提高老年人的准确性。

案卷通过将档案的负责人与“磁号”档案联系起来进行。 我怀疑,从你参考名单看,记录类型的最佳途径是检查贵方的当地磁号码档案(也许可以/使用/共享/魔鬼,但可以查阅男子档案。
