Text File Merger for LLM

Combine multiple text files or entire folders into a single document with clear separators — perfect for LLM context.

💡 Pro tip: Add a .ignore file to any folder to exclude it and all its subfolders from processing. For example, placing .ignore in project/node_modules/ will skip all files in that directory.
