Self-extracting archive

A self-extracting archive is a type of compressed file that contains both the compressed data and a small executable program that allows the user to extract the contents of the archive without needing additional software to do so. ### Key Features: 1. **Executable File**: Self-extracting archives are typically packaged as executable files (often with extensions like .exe on Windows). When the user runs this file, it automatically extracts the contents to a specified directory.
