Hi, Josh,

Depends on definition of "easy and painless". If you are familiar with XML basics then I can suggest such way.
1. BACKUP!
2. Make copies of the whole old course folder - one per each new course you want to make
3. Open first copied folder - lets suggest that it will be course from first module.
4. Open WCL file with Notepad or any plain text editor (some programmers editor with XML highlighting would be more convenient though, Notepad++, for example, is free). WCL is in fact simple XML file.
5. Locate "modules" node and first "module" child node of that node. Delete all other "module" child nodes.
6. Locate "file" child of single "module" node that lasts. This is the folder name and file name of the real module folder. Look in the course folder and delete all folders, except for "courseimages" and the one that should last.
7. Save WCL file. You got the full course from first module.

Repeat these operations (pp.3-7) on each copy incrementing module number and selecting corresponding child "module" node.
