I found this in a few different places around the 'net - hopefully it's helpful:
Try Grouping Files for Effortless Manageability
- In any My Computer window, select View > Arrange Icons by > Type.
- Then, select View > Arrange Icons by > Show in Groups.
- If you prefer Details view, you can right-click on the column header in and choose the columns you want displayed. And you can drag and drop the column headers to reorder them.
