All of us are familiar with files. We save our work (e.g. documents, graphic or VB projects) in a file. If we want to edit our work, we will have to retrieve the file. Files are normally stored in hard disk or diskette. A file is just a collection of related data stored in one unit under one name on a disk. The files that a program accesses are often called data files, or sometimes report files, depending on their format and purpose.
