hard disk space not released after deleted a file

[cheukiecfu]

I deleted a folder(of size >1.5GB) using Shift+delete,
however, the hard drive space is not released after.
I tried running scan disk, but didn't work.
When I look at the drive properties, it has the following
info:
capacity: 22.1 GB, used space: 20.2 GB. (which is
incorrect).
If I select all the files in the drive, and right click
for properties, the size is 18.3GB (which is correct)
(I have selected "show hidden files and folder", so that's
including the hidden files)

What's wrong and How can I get that space back?

Thanks

Empty your Recycle Bin.

Oops, I didn't notice you said you used shift+delete. Sorry.
Are you using Norton Systemworks, with Norton Recycle Bin? If so, that
could be the problem. Empty the Norton Recycle Bin.
