First, we recommend that you familiarize yourself with how "channels" work.
Creating a files channel
To create a new files channel, click on the + on the Files page. Then select one or more clients, or select a company, and submit. A new channel will be created or, if the channel already exists, you will be redirected to it. Depending on the type of channel you create, it will be accessible by one or more of your clients. You can now start adding files and folders.
