Folder Recovery

I  backed up 'My Pictures' folder today because thanks to Windows Update many things got messed up so I had to restore the 'C' drive from 15 days ago. When I run Ghost the 'catalog' search results do not show todays backup since the C drive has been restored to an older version. I know the data is on my external drive but how to I tell Ghost 15 to basically update its catalog of backup data by searching the external drive?  Previous versions of save and restore would allow you to import the actual file data from the backup source updating the catalog. Aby help would be appreciated.
