SD Download Manager is a small and very easy to use file download manager that supports HTTP, HTTPS and FTP protocols. Already at first glance it can be seen that the creator of the application placed the implementation of functions and tools aimed at improving the download of data from the Internet above the graphical interface. These include options for resuming downloads, segmenting (splitting the file into smaller parts) to speed up downloads, queuing data to download, and scheduling tasks to download data at a given time.

There was also integration of the SD Download Manager with the system clipboard (automatic initiation of the download when we copy the link to the file), support for downloading data from locations requiring authorization and support for redirections and proxy servers.
