[ RTC Client Lib ] SC - How to get ChangeSet(All files changes) from IWorkItem item by Program

Source From Here 
Question 
How to get ChangeSet(All files changes) from IWorkItem item by Program. I want a list contains all the files that got change for a RTC. how can I achieve this? 

How-To 
You can see if this thread helps: (from the client side
repository is an ITeamRepository
mgr is an IItemManager (repository.itemManager())
workItem is the IWorkItem for which we want changesets
items holds the set of associated changeset links for the workitem

Below is the code snippet: 
  1. IClientLibraryContext ctx = (IClientLibraryContext)repository;  
  2. IQueryService svc = (IQueryService)ctx.getServiceInterface(IQueryService.class);  
  3. AuditableLinkQueryModel alqr = AuditableLinkQueryModel.ROOT;  
  4. IItemQuery iq = IItemQuery.FACTORY.newInstance(alqr);  
  5.   
  6. iq.filter(alqr.name()._eq("com.ibm.team.filesystem.workitems.change_set").  
  7.   _and( alqr.targetRef().referencedItem().itemId()._eq(iq.newUUIDArg())));  
  8.   
  9. IItemQueryPage itemQueryPage = svc.queryItems(  
  10.   iq,  
  11.   new Object[] { workItem.getItemId() },   
  12.   IQueryService.ITEM_QUERY_MAX_PAGE_SIZE);  
  13.   
  14. List items = mgr.fetchCompleteItems(itemQueryPage.getItemHandles(),   
  15.                                     mgr.DEFAULT, null);  
  16. Set changedFilesAndFolders = new TreeSet();  
  17. for (IChangeSet cs: changeSets) {  
  18.    ...  
  19. }  
You would still need to list files within each change set of items. you have some idea to list files in: 
"How to get an IConfiguration from IChangeSet?"
"how get Full path of the File from changeset Using API?"

Other sources: 
"Setting up Rational Team Concert for API Development"
"The RTC WorkItem Client Link API – Linking to Work Items and Other Elements"

Below is the full sample code which will retrieve change set from workitem and show the file name(s) of change set as well:
