Most file-transfer setups make you invent the structure for every partner from scratch — design the folders, set the upload-versus-download permissions, recreate the routing rules, then do it all again for the next partner. The setup drifts from one partner to the next, permissions get set by hand and sometimes set wrong, and nothing in the system actually knows there’s a path between you and a given partner.
Partner Channels give you that structure out of the box. A channel is a named path with an incoming folder and an outgoing folder, and the permissions are already correct. It matches the way legacy MFT tools organize partner exchange, so a team moving off Sterling, GoAnywhere, MOVEit, or Axway lands on something familiar — running inside the Partner Workspace that keeps each partner walled off.
