How to get the files from a Null versionhandle ??

Hello Team

Usecase : I am deleting the file from a changeset
How do i get the deleted file name from a null versionhandle ??

IConfiguration configuration = tempWSConnection.configuration(component);
                    List changesFilesList = changeSet.changes();
                    for (Object changedFileObj : changesFilesList) {
                        Change changedFile = (Change) changedFileObj;
                        versionableHandle = changedFile.afterState();
                        filesToSearch.clear();
                        System.out.println(versionableHandle);
                        if (null != versionableHandle) {
                            filesToSearch.add(versionableHandle);
                            ancestor = configuration.locateAncestors(filesToSearch, monitor);
                    }

In this above code i get the versionableHandle as null for the deleted file ,How do i get the file name from this ??
