They fully support file & directory permissions, just as Linux system has since the beginning. Together, we'll now assess a directory listing from our Lab Linux system hosting server, to help us understand the information provided. a simple 'ls' command will give you the file and directory listing within a given directory, including the option  '-l' will display number of new areas that we are going to discuss here:

How to create a Hirens Boot CD 15.2 USB Disk

Hiren’s BootCD (HBCD) is a bootable CD that contains a set of tools that can help users to fix their computer if their system fails to boot. More specifically, HBCD contains hardware diagnostic programs, partition tools, data recovery utilities, antivirus tools and many other tools to fix your computer problems.  I write this article because I use Hiren’s BootCD frequently to troubleshoot computer problems, specially when a computer doesn’t boot anymore due to a virus attack or due to a corrupted file system. In this article you will find instructions on how to put Hiren’s BootCD on a USB flash drive (stick) in order to troubleshoot computer problems in the future.
