Clonezilla, using either partclone or partimage as a backend, works at block-level to make binary partition images. You cannot extract individual files from these images. The purpose of clonezilla is to quickly clone your system to minimize downtime if accidents happen (or to deploy tenth of identical machines on a LAN in a few minutes) and instantly restoring a complete working system.
Edit: If you want something like ghost explorer, use fsarchiver which works at file-system level and its GUI, qt4-fsarchiver.
