GbxDump is a Microsoft Windows application to show the contents of the file header of GameBox "Map", "Challenge", "Replay", "Pack", "ObjectInfo" and "Item" files. It was created by Wolfgang Rolke.

After installation the context menu of GameBox (Gbx) files has an additional entry "Gbx File Dumper". Using this command you can examine this Gbx file. You can also run the tool from the start menu and open any Gbx file within the program (Start » Programs » Gbx File Dumper). Nevertheless, the easiest way is to use drag-and-drop from Microsoft Windows Explorer. Then several files can immediately be analyzed at once.
