A team project consists of metadata and media references that are stored in a database hosted in Adobe’s Creative Cloud. The media used in your team project can be stored in various locations such as a network shared storage, a local hard drive, or via cloud storage synced to your desktop such as Creative Cloud folders, Dropbox, or OneDrive.
To import a media into a team project:
Each collaborator on a team project must have access to their copies of media used in the team project, or the media appears offline. However, collaborators can access media in different locations, as team projects allows for user-specific media mapping. This helps the co-located users using media in network shared storage to collaborate with remote users who access media (likely proxy files) in a different (often cloud-synced) storage location.
