Data File Analyser - Visualise File Data & Structure

Data File Analyser is a free utility for inspecting and understanding the structure of any data file.

It allows you to open a file and visually highlight specific byte ranges or sections, making it easy to identify where certain data is stored. This is ideal for debugging file-format issues, verifying that applications are saving data correctly, reverse-engineering file layouts, or demonstrating how a file is structured.

You can create multiple overlays to mark different regions of interest, then save those overlays for reuse on other files of the same format - perfect for repeated analysis or documentation.
