Until recently, there was no file transfer utility on the Facebook Platform. You could send fairly large files of limited size. But, now “Pipe” lets you send a file of up to 1 GB to your friends on the network, using a secure peer-to-peer approach (not unlike the Skype file sharing system, but on Facebook…not Skype…obviously.
Makes it much easier to send a big file without having to jump out to DropBox or another system while using Facebook. There’s a storage locker function that lets you lodge a file up to 100 MB for three days if the friend you’re trying to send a file to is offline.
Neither Pipe nor Facebook sees your file, there is no intermediary and the Facebook API ensures that only your friend can get the file.
