In order for any type of program or operational system to work and run smoothly, it needs a properly organized file system from which information can be retrieved in order to carry out functions and work. A category of programs called file managers are used to access and manage files and directories through a graphical interface. They can be local like the files in your computer or they can be web based like the management of the files of your website. File managers allow you to view, edit, move, copy, create, and delete files, whether they be on your computer or on a server. Their GUI (graphical user interfaces) provides the structure and the hierarchy of folders where your files are stored.
