We have a Netware 6 server running Border Manager 3.7. We also use Surf
Control and download the updates weekly.

This past week, the Surf Control downloads ran the SYS volume out of space.
This was surprising because we have a 15 GB SYS volume and it should have
about 7 GB free. If I right-mouse click the volume and check statistics,
we have less than 1 GB free. BUT, if I highlight all directories on the
SYS volume and all files, and right-mouse click to check properties, the
space in use is only 6GB.

So, I have a 15GB volume, with 6GB in use, but reports only 1GB free ?

Can someone explain this to me ?

Is there a way to restore the lost space ?
