Windows programs (Easy CD, etc) use a combination of
packet writing and the UDF filesystem.  This allows
your to treat the CDRW as a 'large floppy' with
random access read/write and drag-and-drop abilities.

Although the bits and pieces for Linux are improving,
I'm not sure if there's yet anything like "Easy CD Creator"
with that kind of on-the-fly random access read/write
capability (where a mounted CDRW is treated like any
other random access disk with read/write/delete/rename
that automatically reuses deleted space).
