Upload files however is most convenient for you. Use the Planfix interface (in a task comment or with drag and drop), respond to an email, or use the API.
Add local files to tasks or attach links to online documents. If the file added already exists in the current task or project, Planfix will prompt you to choose another option to avoid file duplication.
Attach unlimited comments and files to tasks, where they will be stored. Find the comment or file you need at any time in the task card.
