I'm using Ghidra to work out the structure of some binary files. No code.

I can use the Structure Editor to define a struct, such as the header of the file format.

But I can only find a way to create the struct in the context of one of the files and then it will not be visible to the other.

Is there a way to make it visible to both?

I have two PNG files open in tabs Ghidra Listing panel with two tabs

Now on the bottom right in Data Type Manager I create a new archive file foo.gdt

Click the small black arrow -> New File Archive

Ghidra Structure Editor

In that .gdt archive I create an arbitrary structure with three dwords named pngheader, pngtail, pngfeet

Ghidra Data Type Manager

Now I can apply this structure to both files using data->choose data type (press T shortcut) as below

Programs in the same project can share data types through the data type manager of each program. This can be done using drag-n-drop from one data type manager to the other or through copy (Ctrl+C) with focus on the type and paste (Ctrl+V ) with focus on the directory or top level archive where the data type should be copied to.
