--- HOW TO USE THIS SCRIPT ---

if name == "main":
# 1. SET THE FOLDER YOU WANT TO SEARCH
# Example for Windows: 'C:\Users\YourUsername\Documents'
# Example for macOS/Linux: '/Users/YourUsername/Documents'
# IMPORTANT: Use an absolute path for best results.
search_path = "C:\Users\YourUsername\Documents"

# 2. SET THE KEYWORD YOU ARE LOOKING FOR
keyword_to_find = "report" 

# Run the search function
results = find_files_by_keyword(search_path, keyword_to_find)

# 3. PRINT THE RESULTS
if results:
    print("--- Found Files ---")
    for file_path in results:
        print(file_path)
else:
    print(f"No files found with the keyword '{keyword_to_find}' in that location.")
