Working a lot with PowerFactory can lead sometimes to quite large result objects which occupy space on the hard disc. The attached Python script can list for you the total size of each project to help you finding the big fish.

You can activate the project after execution via right click at the project name in the output window and select activate. After this you can open the result object from the output window and - if the data is no longer needed - you can delete the data by pressing the "clear" button.
