SFBinaryData class is a successor of the BinaryData class in ZmeY soft Utility ActiveX Objects library. It supports the same features except ReadFromFile and WriteToResponse methods which do not conform to the newObjects Pack1 standards. The functionality of these methods can be achieved through SFStream object and setting/getting the Value property and WriteToResponse is a matter of Response.BinaryWrite o.Value and such a method is not actually needed for anything.

SFBinaryData implements new members which allow the programmer to do a lot more with binary data in memory. Now it has methods that are able to write/read strictly typed values in arbitrary positions in the binary block in memory. Also string values can be read/write both ANSI and UNICODE. Both features also support control over the byte ordering - you can configure object to use little endian or big endian format for numeric values and UNICODE strings. These features together with the record based access (see SFRecord, SFField, SFFilter) and direct access to binary streams (SFStream) allows the scripting applications to manipulate virtually any available data or file format directly on low or higher level. Using these objects the developers are enabled to do entirely in script format conversions, dig for data in files/data streams of any origin, build script routines, libraries, components to provide access to certain file formats from ASP pages and other applications. 

What can you do this way? For example design a script that reads MP3 file information, or digs information from an executable file, extract useful data from image files and so on. Of course, this is not easy - you need to read the corresponding format specification and do all the dirty work, but you can do all this in your script (ASP page, NSBasic application etc.) without need to build helper components in another language.
