You can download your asset files using the advanced search feature. Go to Advanced search -> "All Assets" -> "Select all results" -> "Export results".
Select the output type "CSV", and "Encoding" then the columns you want to export. To do this, perform a "drag and drop" action between the available and selected columns (those for your export).
Then, click on "Validate". Your export will be available in the notifications of the dashboard.
