They create premium links, usually far faster and bigger than common ones (you can easily get files over 10GB). Some sites are specialized in streaming have embedded players. Kikisso provides a list of free and paid PLGs, showing characteristics as rank, language support, download limits, link generation capacity, ssl support, max file size. There is extensive information about each premium link generator, so you might take some time to read their specificities.
