Folders structure

Hi,

Is it possible to change display of folders structure?
For example, there are following directories on server:

• files
  • r1
    •  _thumbs
    • 0
    • 1
    • 6
    • 7
  • r2
    • _thumbs
    • 18
  • d1
    • _thumbs
    • 0
    • 3
    • 4
    • 5
  • d2
    • _thumbs
    • 5
    • 6
    • 7

I want to display only few of them and change their names:

• Lorem (r1)
  • Ipsum (r1.0)
  • Dolor (r1.1)
• Sit (d2)
  • Amet (d2.5)

Luigi

Thanks
