All plans. On by default.
Attach files to tasks and projects so the artefact sits with the work it
belongs to rather than in someone’s inbox.
Uploading
Drag onto a task or use the attachment control. Files are scoped to the
project, so project access governs who can see them.
Storage limits
Storage is pooled per plan and shown against your usage under
Settings → Billing. Larger plans carry more.
Sharing
Files inherit the access of the project they’re on. To share with a client,
use the Client Portal or a project’s public status link
rather than sending the file out of band.
