File System & Storage#
What is a file system?
The file system is made up of resources such as files and folders (directories). Folders can contain both folders and files. Files contain neither files nor folders. If a directory x contains a directory y then we say that x is the parent of y. The file system is like an upside-down tree with the root directory at the top of the tree and branches of nested folders terminating in files and empty folders–the leaves of the tree.
We are always in some directory in the filesystem. This directory is called the working directory.
An absolute path (to some resource) is the path (to that resource) relative to the root directory.
A relative path (to some resource) is the path (to that resource) relative to the working directory.
