## What are the file size limits?

The current file size limit on Highway is 1 GB per file, but there are no restrictions on the total file sizes per submission link or per collection.

## What data classification and information sensitivity can Highway handle?

Up to Restricted/Sensitive Normal.

## Can recipients submit files multiple times via the same submission link?

Yes, this is possible. Please note to set a longer expiry date for your submission link if you wish to allow your recipient to have access to your link for repeated submissions.

## Can collections and submission links be deleted?

Unfortunately, this is not a feature that is available at the moment. 

## Why can't I upload files from my GSIB/HVB?

Highway is designed to enable file collections from citizens and not for government / healthcare / education officers to share files externally, hence uploads from certain IP address has been banned intentionally.

## My agency is migrating email domains, what should I do? 

As collections are tied to email addresses, this means that you will lose access to all collections if a proper transition period is not in place. Please set a transition period where each admin have to transfer all active collections to their new email addresses.

 You may follow the instructions below to add collaborators:
