The Progressive Downloader download manager is developed for macOS systems. It operates with HTTP, HTTPS, FTP and SFTP protocols. The application manages download queues, splits files into segments for concurrent transfer and automatically locates alternative mirrors. It includes an integrated browser for FTP and SFTP servers. The drag and drop function for text with links initiates downloads. The program resumes interrupted transfers when the system is reactivated or the application is restarted.
