A file transfer is how a finished film, a second shooter's card or a set of raw files gets to where it is going. Until now the studio's own upload sent each file in one go, one at a time, and could not take a file over a few gigabytes, which ruled out most finished films.
Sending
Each file can be up to 100 GB. Large files go up in pieces, so a wobble on the connection resends one piece rather than the whole film, four files go up at once, and the progress shows how much is left. Stop, close the laptop, and drop the same files again later: what already landed is skipped. A whole folder can be dropped, subfolders and all. Each file is on the delivery as soon as it lands, and the client is not emailed until everything has.
Receiving
The client's page shows photographs as a grid and plays films in place, so they can watch before they download. Download all no longer builds one archive in the browser: smaller files come as ZIPs in parts of under a gigabyte, written as they download, and big files download on their own, where the browser can pause and resume them.
Before the link closes
Two days before a transfer's end date, a client who has not downloaded everything gets a reminder from you, with the link. Links past their date now show as expired in your list.
