    • /root/ root user(super user)'s home directory
    • /mnt/ include the mount point of file system mounted after system boot
    • /boot/ files used when kernel and other system boots
    • /lost+found/ fsck(file system check) use this directory to store scattered files(some file unnamed)
    • /lib/ include some library file used by command in /bin/ or /sbin/
    • /dev/ device files
    • /etc/ configuration files and directories
    • /var/ variable files(or files keep being modified), like log file or printer spooling files
    • /usr/ include most things related to system users, like applications and supported library files
    • /proc/ a virtual file system (actually not store on disk), include contains some system information used by some applicetion
    • /initrd/ somethings used to boot your system, DO NOT DELETE IT
    • /tmp/ temporary directory for application and users, every one could read and write files in this directory
