Computer files are often even more valuable to us than paper files. Yet if they are not stored in a manner that allows safe, easy retrieval, they become useless. The purpose of this document is to impress in users' minds the importance of good file management, and to give several ideas for ways to make file management as simple and effective as possible, while maximizing privacy, minimizing risk of loss, and reducing costs. In order to understand good file management, you must first understand the structures available to computer users through the use of disks. Directories are the computer's way of organizing the many files that can be placed on a disk.
Every disk has at least one directory.
From the root directory of every disk we are able to directly or indirectly access every file on the disk. The root directory can hold directories or files. Subsequent directories can also hold directories or files, and so on. . . The root directory has no parent directory, but only child directories. Each major topic or subject in one's data could be placed in its own directory.
