Linux File System

Linux speaking files are stored in a single directory structure (virtual directory), and the virtual directory contains the file paths of all the storage devices installed on the PC.

The more complex part of the Linux virtual directory is how it coordinates the management of each storage device. The first hard drive installed on a Linux PC is the root drive, creating some special directories on the root drive that we call mount points. Mount points are directories in the virtual directory that are used to allocate additional storage devices.

Virtual directories cause files and directories to appear in these mount point directories, but in fact they are stored in a different drive.
