The Binary Internals Desktop Viewer is a self-contained Swing application that parses binary files and presents their structure as an interactive tree. This page walks you through downloading the JAR from GitHub Releases, launching it, opening your first file, and navigating the three-panel layout.

Recent Files

The File → Recent Files submenu keeps track of the last 10 files you opened in the current session. Click any entry to reopen that file without navigating the file chooser again.
