Can I show file modified, created etc dates as Sat. Mar 1, 2017?

They will show using whichever format you have Windows set to use in the Windows control panel for setting date, time and number formats.

You can also use script columns to display dates using any format you want, if you want a special format in Opus and don't want to change the format that everything else uses.
