moving folders in dfs doesn't free up drive space

Archived from groups: microsoft.public.win2000.file_system (More info?)

Our Dfs setup on one drive is quickly filling up; we moved a 6G folder
from the root dfs folder (D drive) to another volume (E drive) on the
same server to free up some drive space, but the freed up drive space
isn't showing up.

The dfs folder shows the correct post-move size of all the
folders(17G). The remaining (non-dfs) folders on the drive should add
up to 20.3G, leaving 45G on the D drive free, but instead the used
space shows up as 65.5G, leaving just under 3G.

How do I get the drive space to show accurately? Why wouldn't moving
the physical location of one folder to another drive free up drive
space on the original drive? The server has been restarted since the
move and the used space is still 65.5G.

Any help would be appreciated!
