The Files section is a tree of every Lua script the debugger knows about:
.lua file discovered under the global and personal
plugin directories (shown even before it has been loaded, so
you can open it in the editor and set breakpoints in advance).
Each leaf row’s tooltip is the absolute path of the script. Double-clicking a leaf opens the script in a new editor tab (or switches to the existing tab if it is already open). The tree is rebuilt whenever plugins are reloaded or a new script is loaded, so newly pulled-in `require`d files show up without restarting; the tree is fully expanded after every refresh.
A right-click context menu on a script leaf offers Open Source (same as double-click), Reveal in File Manager (opens the containing folder in the platform’s file browser), and Copy Path (copies the absolute path to the clipboard).
