Hi Sergi,
Greetings from Syncfusion support.
We have reviewed your query and understand that you have
requested to add additional columns in the details view pane of the File
Manager component. We have prepared a sample on our end and added the
additional columns that you have shared using the detailsViewSettings
property.
With this property, you can add additional columns to the
details view pane and dynamically switch them based on the user or your
requirement.
We have attached sample for your reference.

Check out the shared details and get back to us if you need
any further assistance.
Regards,
Suresh.
