The Problem:

I can’t upload very large files to Box.

As a media and entertainment professional, your workflow consists of uploading and storing huge files. Box is a great cloud storage solution that also offers many other robust features (e.g. collaboration), but it’s lacking in terms of upload size. Box has a file upload limit of 150 GB — and that’s only if you pay for an Enterprise Plus account.

The Solution:

MASV’s Box Integration: The best way to upload large files and migrate files into Box.

With MASV, you can create a MASV Portal to upload large files to Box — we’re talking about a 15 TB file limit!

A MASV Portal is a secure upload portal that connects to your Box account. This cloud integration allows for the accelerated ingest of large files into Box storage without having to enter login credentials.

Just share a Portal link with those you want to receive files from, and watch as the files appear in your Box account.

Say goodbye to inconvenient file upload limitations forever with the MASV x Box integration.

Box offers seven different permission levels and the ability to manage folder and file permissions.
