About the File Type Analyzer utility

To assist you with analyzing custom file types, you can use the
Symantec Data Loss Prevention
File Type Analyzer utility.
The File Type Analyzer utility helps you find the commonalities and attributes that describe a custom file type. This data is often referred to as "magic bytes" because they are unique the characters that positively identify the file type.
The File Type Analyzer utility is a standalone Java application that features a graphical user interface. This utility enables you to perform the following operations:
  • Read in a collection of files from a directory or directories (the "data set").
  • View and compare the unique bytes for each file in the data set.
  • Analyze the bytes across files and determine those that are consistent.
  • Test a custom file type detection script.
  • Save and open data set configurations and test scripts.
