.SH DATA STREAMS
All data on NTFS is stored in streams, which can have names. A file can have more than one data streams, but exactly one must have no name. The size of a file is the size of its unnamed data stream. Usually when you don't specify stream name you are access to unnamed data stream. If you want access to named data stream you need to add ":stream_name" to the filename. For example: by opening "some.mp3:artist" you will open stream "artist" in "some.mp3". But windows usually prevent you from accessing to named data streams, so you need to use some program like FAR or utils from cygwin to access named data streams.
