FileInsight is a hex editor from McAfee designed for analyzing malicious files. While FileInsight is used primarily for examining Windows executables, some of its features make it a good general file analysis editor. For example, examiners can apply data structures (C or C++ header files) to interpret files. This can be used to apply logic to the binary file format being examined. Prebuilt interpreters are included for Windows executables and Office binary documents, as well as a variety of date and time formats. The content of a file can be modified in-place using JavaScript, which can be useful to apply decoding functions or other content transformations. Finally, plugins can be developed using Python for more extensive tasks. FileInsight is available from mcafee.com/us/downloads/free-tools fileinsight.aspx.
