Recovering Files From A Multisession CD?

[TheFrog]

My neighbour has just installed a free burning programme (Burn4free). Whilst adding files to a previous multi-session CD, he accidentally closed it and can now only read the last files added.
Is there any way the previous files (mixture of data/jpeg/mpeg) can be recovered?
