Multi-source downloads

From PowerFolder Wiki

PowerFolder by default can download a file from multiple sources which have the complete file. The biggest advantage of this feature is is that data can be distributed much faster. Most connections allow significant higher download than upload rates, this means that you cannot use the full potential of your connection. With PowerFolder you can use the upload of multiple connections, this means the more members a folder has the faster you will have your data. This feature is especially usefull for connections over the internet with more than 4 computers and larger files.

Of course you can disable this feature under preferences/network if you prefer.
