Object entry, int level, IProgressMonitor monitor) {
		if (monitor.isCanceled()) {
			return false;
		}
		monitor.subTask(NLS.bind(
				DataTransferMessages.WizardProjectsImportPage_CheckingMessage,
				structureProvider.getLabel(entry)));
		List children = structureProvider.getChildren(entry);
		if (children == null) {
			children = new ArrayList(1);
		}
		Iterator childrenEnum = children.iterator();
		while (childrenEnum.hasNext()) {
			Object child = childrenEnum.next();
			if (structureProvider.isFolder(child)) {
				collectProjectFilesFromProvider(files, child, level + 1,
						monitor);
			}
			String elementLabel = structureProvider.getLabel(child);
			if (elementLabel.equals(IProjectDescription.DESCRIPTION_FILE_NAME)) {
				files.add(new ProjectRecord(child, entry, level));
			}
		}
