Their documentation seems rather sketchy:
http://www.sysresccd.org/Quick-start...e_console_mode
The files and directories are not similuated, but they are virtual. They are in a
Ramdisk.
You would need to know how the file systems are being seen by the rescue cd. Running fdisk -l should tell you that. Once you know that, the rest is easy.
Then you would mount them by creating a mount point in /mnt or /media, followed by issuing the mount command.

Once the drive is mounted, you can navigate in mc to the mount point you created and take a look at the files and directories.
I would suggest using a GUI environment until you get the hang of this. SystemRescueCD
provides one.
If that's not adequate or if it is confusing, download and burn a copy of
Knoppix.
