A simple Visual Studio Code extension that adds a right-click folder action to recursively merge all files inside that folder and its subfolders into a single output.txt. Useful for passing as context to LLMs for debugging, packaging, or reviewing multiple source files at once.
Optimized for JS/TS projects, but works well with anything.

How to Use
Right-click on any folder in the Explorer sidebar.
Select "Merge files recursively"
A file named output.txt will be created inside that folder, containing all merged content.
Notes
Only visible when right-clicking on folders (not files).
Output file is always named output.txt and will overwrite any existing file with that name in the selected folder.
Supports large folders, respects .gitignore intelligently.
