Unix already has this, and their called extended attributes, and I hate them with a burning passion. Rsync, cp, any tool that manipulates files (tar for example) has to be able to capture this data, and just reading the file won't do it anymore. Oh and to make things more "fun" FreeBSD, Linux and Mac OS X at least have different ways of dealing with them, and max size limits etc.
you forgot NTFS's version http://www.wikistc.org/wiki/Alternate_data_streams echo plain > t.xt echo hidden > t.txt:hidden.txt %type t.txt plain % type t.txt:hidden.txt The filename, directory name, or volume label syntax is incorrect. % notepad t.txt:hidden.txt hidden
