You just create a shared link for that file from within Box, then share the link directly or copy and paste it into an email or message to share with any recipient.

How can I send large video files online?

You can easily share large video files from Box by creating a shared link for the file. That link can then either be shared directly within Box, or you can copy and paste it into a message or an email.

How do I send a large file to someone?

The best way to share large files with someone is through Box. Our file sharing software allows you to upload big photos, videos, documents, presentations, and other media and simply share them with other people via a link. No need for external storage or entering a huge amount of personal information to access the platform.

  1. Sign up or log in to your Box account
  2. Drag and drop your content
  3. Copy and share your shareable link

Once recipients receive the link, they access the content via browser or mobile device, even without a Box account.

What is the upload limit on Box

The maximum file size limit for uploads on Box depends on your specific account plan.

How can I send a large video file to someone across the world without it timing out?

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.

What is the difference between TCP and UDP protocols for high-speed file transfers?

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.

Is file transfer protocol (FTP) still safe for business, or are there faster, more secure modern alternatives?

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.
