How to delete output items from past analysis executions?

[Datino]

In the analysis tasks tab, I can see the list of my analyses, and the output objects generated for each one during past executions. 

How do I delete these objects? as I've done some changes, some objects are not needed anymore and the list is growing too long to manage.

What product are you working with?

It was Risk Management, I found the objects somewhere in the installation folders.
