Where is my 2G? - BUG in Ubuntu?

[Paul Schulz]

Another place where files can be 'hidden' is in the '.Trash' directory
at the top level of the filesystem.. eg. On a USB stick, look in the
top level directory of the stick.

You may need to explicitly delete this directory free up this space if
you delete files in Gnome.

Cheers,
Paul
