Need to create a new project from existing help files

[CAMS-Help]

I work for a company with various software products. The person that maintained the Help project for one of those products has left the company and the project can not be located. I was able to secure the Webhelp folder created through RoboHelp containing hundreds of HTM files that are currently linked within the program. What is the easiest way to create a new project and transition those files into the project without importing each separately?  I also need to retain any old map ids so Coding will not have to reestablish those links. Any help would be appreciated!!
