Securely share large files

Box makes it easy to send large files of any type to anyone, even if they don't have a Box account. Simply create a shared link for that file, then share directly from Box or copy the link to share via email, chat, Slack, or another messaging format.

The maximum file size limit for uploads to Box varies depending on your account type — from 250MB to 150GB. To see the maximum file size limit for your account, follow the instructions on this page.

Box transfers enable you to send large media through your existing email address without triggering a “file is too large” error message.

You can use Box to send large video files to someone without time-out issues. Our default web session duration is 14 days, which prevents timeouts during long transfers. Transfer large files securely regardless of geographical distance: If a connection drops, you can use our resumable upload feature to continue uploading your videos from where you stopped, rather than forcing a total restart.

Cloud storage is the best option if you want to keep your files safe during transfers. Common file transfer services often lack persistent security and compliance features. 

Cloud storage platforms like Box provide a secure home for your content with built-in version history and an audit trail, allowing for ongoing secure collaboration and version control that simple transfer tools don’t offer.

Transmission control protocol (TCP) establishes a reliable connection to guarantee that every piece of data arrives in order. User Datagram Protocol (DCP) prioritizes speed by sending data without waiting for confirmation, which benefits live streaming but lacks the reliability required for a complete secure file transfer.

Box uses TLS 1.3 as the standard protocol to encrypt content uploaded to Box in transit, which operates over a TCP connection.

Standard FTP remains a security risk because it lacks built-in encryption and sends credentials in plain text. Modern alternatives like secure file transfer protocol (SFTP) or an Intelligent Content Management platform like Box provide a more reliable way to transfer large files securely, as they include access controls and encryption to keep your data safe during transit.
