How to organize the folder structure in build definition

Isn't "Component Load Rules" there?

http://publib.boulder.ibm.com/infocenter/clmhelp/v3r0m1/topic/com.ibm.team.build.doc/topics/r_scm_build_loadrules.html

Worst case, just load everything and let your build script handle it.

The problem is:

I have identical top level folder name in both component. So if load from the top level, RTC will complain one component is being overwritten by anther.

This is a legacy system migrated to RTC, it is not easy to reorganize the code structure due to the whole build/release history. So I am looking for a way to compromise the gap at code loading.

Also, I tried to created the load rule in each component.
In the first component, the file contains:
RootFolderName=/modules/thirdparty

The second component, the file contains
RootFolderName=/modules

The third component, the file contains
RootFolderName=/build_system
RootFolderName=/installer


I am getting error message from the build.

 I have the same error because the load rule put the content of "Main Folder" at the root extraction folder and ignore the "Main folder".
