Retrieve data from all sessions
on multi-session discs
When you write files to a CD or DVD media you usually have two options. You can burn the whole disc at once or you can write data in several successive sessions. In the latter case you will create a multi-session disc. When you browse the content of such disc with regular software, you will usually see files from all sessions and they will not be divided by sessions anyhow.
However if a newer session contains a new version of a file that was also present in one of the previously burned sessions, you will only see the last version. The old one will physically remain on disc, but it will not be accessible.
Recover Disc can read resolve this problem. When it finds several versions of a file in different sessions, it lets you choose which version to extract. It also has an Expert View mode to browse full disc structure with all tracks and sessions.
This way you can browse the content of each session separately.
