Duplicate File Detector

You are given a list of directory information entries, where each entry contains a directory path followed by one or more files with their respective contents. Your task is to identify and group all files that have identical content across the entire file system.

Each directory entry in the input follows this structured format:

• "directory/path filename1.ext(content1) filename2.ext(content2) ... filenameN.ext(contentN)"

This notation indicates that within the directory "directory/path", there exist N files. Each file is represented as filename.ext(content), where the text inside the parentheses denotes the actual content of that file.

Your objective is to analyze all files across all directories and return groups of file paths where each group contains files that share exactly the same content. A valid group must contain at least two files with matching content. The output should list the complete file paths in the format "directory/path/filename.ext".

Important Notes:

• Files sharing the same content form a single duplicate group regardless of their location or filename
• The order of groups in the output and the order of paths within each group does not matter
• A single blank space separates the directory path from file information within each input entry
• The root directory is represented by the starting path component (e.g., "root" or "home")
