The File Manager Application is a command-line interface (CLI) tool designed to simplify file and directory management tasks. It provides a set of commands to perform basic file operations, navigate through directories, and gather information about the host machine's operating system. With support for Streams API, hash calculations, and file compression, this application offers a versatile set of features for users who prefer working in a terminal environment.
