Using the program is really simple: first you have to log in with your Facebook account, then choose what you want to share (no matter its size). Finally, select a contact from your list, and the material will be sent.
From the interface, you can see all the files you've sent to date, as well as the contacts you sent them to. Besides that, you can add comments and read those other people have left, so you can get direct feedback on the content you send.
Downloads are totally safe, and only the recipients have access to them, so you don't have to worry about your files ending up in the wrong hands.
Share is an excellent alternative for sharing files between friends. If you need to send large videos or other types of files, give this app a chance; it might well be a great help.
