In Details view:
- Shift-Click the Name column heading. That will lock the folders to the top of the list.
- Click the Last Modified column heading to alternate between ascending and descending sort by date.
If you want to make this the default view for all folders of the same type, click View tab, Options, Change folder and search options, View tab, Apply to Folders. Note that this procedure will not update file open/save dialogs for folders that have been previously opened via a file open/save dialog.
If you want to apply that view to ALL folder types, including file dialogs, you'll need to use this tool: WinSetView
