Using Files and Directories operating system uses a hierarchical file system for organizing files and isolating related files. The section Understanding Disk Files describes the file directory structure. With large storage devices, it is particularly important that you carefully organize your file structure so you can quickly locate needed files. Carefully-organized files make common operations, such as copying, deleting, and renaming files, much easier. It is very difficult to clean up a badly disorganized file structure. Therefore, before you begin copying large quantities of files to your system storage device(s), carefully read the section Understanding Disk Files .
