You can later use Freezepointing to recreate the source hierarchy. You specify the name of the freezepoint file, the path name of the directory hierarchy from which the deltas are to be extracted (if different from the hierarchy from which it was derived), and the directory where you want the source hierarchy recreated.
The extract operation consists of creating a new directory hierarchy based on the information contained in the freezepoint file. The new hierarchy is comprised of g-files defined by the default deltas in the original SCCS history files; the history files themselves are not recreated unless you ask FreezePointing to create a workspace while performing the extraction. Deltas are extracted from SCCS history files located in the original source workspace.
