发明名称 Structure of a combination file folder
摘要 An improved structure of a combination file folder includes a pair of clip boards and a connection board which mounted together to form a file folder. The file folder is made from plastic materials and can be detached from one another. Thus, the packaging and transportation costs are greatly reduced, as the file folder does not occupy a large space. Based on the need of the size of the file folder, the change of the connection board can satisfy the needs of the consumers.
