(HexInsight description
Advanced hex / structure editor which can edit binary files with structures
HexInsight is an advanced and reliable application designed to enable you to view and edit binary files. In addition to a flexible and fast hex/binary editor, it also has a built-in powerful scripting engine which is used to run the scripts that can parse complex binary files into hierarchical structures to let you explore the internals of binary files and edit them.
By using HexInsight, users can also process the files easily. For example, users can extract the video or audio data in a AVI file by simple selecting "dump audio". Users can also write scripts to parse any other file formats and process the files.)
