; __/etc__ : configuration files for programs
; __/home__ : one subdirectory for each user to store all their personal files in. Your own subdirectory here is called your home and is commonly abbreviated as __~__, though this must be explicitly supported by the program in question (all shells do).
; __/lib__ : libraries needed to run the programs in __/bin__ and __/sbin__
; __/mnt__ : MountPoint for temporary filesystems (eg CDROM, floppy disk)
-; __/opt__ : add on
software. Usually StaticallyLinked programs provided in binary form. Some people install [TarBall]s in here too, especially beta software.

software (as opposed to LinuxDistribution installed software)

programs provided in binary form. Some people install [TarBall]s in here too, especially beta software.
; __/proc__ : a virtual FileSystem containing pseudo files with information about the hardware and kernel configuration and the running processes
; __/root__ : home directory of the __root__ SuperUser
; __/sbin__ : executable files only of interest to the __root__ SuperUser
; __/usr__ : files that can be shared across a whole site among multiple users
; __/usr/local__ : anything shared across the system but not supplied by the system vendor traditionally goes here - most commonly, packages compiled from [TarBall]s
; __/var__ : variable data files, such as logs, mail and printer spools
-; __/tmp__ : temporary files - that is ''literally'' temporary files. On some systems this directory is frequently purged, and on machines with modern Linux kernels it may be mounted as [Tmpfs] FileSystem that exists only in memory.
+; __/tmp__ : temporary files - that is ''literally'' temporary files. On some systems this directory is frequently purged, and on machines with modern Linux kernels it may be mounted as [Tmpfs] FileSystem that exists only in memory. When virtual memory was not as good as it is today, many userland programs had to explicitly balance memory and disk consumption in /tmp/, and some still do (such as find(1))
