To import files to Canto that have been shared to an Upload Link (by outside collaborators):

Navigate to Settings, and then select the Links & Connections tab, followed by the Upload Link sub-tab. 

2) Click the Review button next to the Upload Link.

3) The files will be displayed in a new tab. Select the files to import.

4) Drag the files to an album in the Folder and Album structure, unassigned into your main library, or a Workspace. All of the selected files will be dragged together. 

Note: Assets cannot be dragged into a folder.

A confirmation window will be displayed when the import is complete.
