Look. I have ZIP archives prepared in different os'es: mac, linux, windows. In windows file names encoded in DOS CP866, mac & linux in UTF-8. I need to know (in code) in which os zip file was prepared to decode file names correctly. There is a Host OS paramterer in "Central directory structure" of zip file (look http://www.fileformat.info/format/zip/corion.htm ). How to get 0005h 1 byte Host OS parameter in C#?
A:
Can you use a StreamReader to get this particular position in the file? I believe you can tell it what offset and length you'd like to read, and it will fetch that set of bytes of you, which will tell you the OS.
