Open the dialog "Job".
Choose your desire destination "category", optional change the destination "folder", adjust the number of threads (Transports), and even enter the sheet "Other Settings" to set the proxy and its mode, etc. After finished various settings, click "Save as..." to save the current "scheme". But page "Schedule", fields "URL", "Refer" and "Rename" are not saved.
Later Net Transport uses the current scheme settings to download the jobs, and when they are over, move them to your desire folder and category automatically.
The benefit of scheme is that you can quickly switch settings according to actual requirement.
