# Filesystem Standard (Kali)

Kali linux is organized to be consistend with the *Filesystem Hierarchy Standard* (FHS), allowing users of other Linux distrobutions to easily find their way around Kali.  The FHS defines the purpose of each directory.  The top-level directories are described as follows:<br>

* `/bin/` : basic programs
* `/boot/`: Kali Linux kernel and other files required for its early boot process
* `/dev/` : device files
* `/etc/` : configuration files
* `/home/` : user's personal files
* `/lib/` : basic libraries
* `/media/` : mount points for removable devices (CD/DVD-ROM, USB keys, and so on)
* `/mnt/` : temporary mount point
* `/opt/` : extra applications provided by third parties
* `/root/` : administrator's personal files
* `/run/` : volatile runtime data that does not persist across reboots (not yet included in the FHS)
* `/sbin/` : system programs
* `/srv/` : data used by servers hosted on this system
* `/tmp/` : temporary files (this directory is often emptied at boot)
* `/usr/` : applications (this directory is further subdivided into `bin, sbin, lib` according to the same logic as in the root directory) Futhermore, `/usr/share/` contains architecture-independent data.  The `/usr/local` directory is meant to be used by the administrator for installing applications manually without overwriting files handled by the packaging system `(dpkg)`.&#x20;
* `/var/` : variable data handled by services.  This includes log files, queues, spools, and caches.
* `/proc/` and `/sys/` are specific to the Linux kernel.  They are used by the kernel for exporting data to user space.
