Like an Outlook or Project schedule? Tasks can be executed by external programs via API.
I don't think there is anything like coldstorage out of the box.
Hi Amit -
If you are writing your own task add-in you can set up scheduling. (Refer to the Programmers Referencece and the online documentation topic Tasks > Creating a New Task > Task Properties - Scheduling)
The two 'out-of-the-box' tasks (Convert and Print) do not use the scheduling option.
