# Filesystem

### The Linux Filesystem

The directories you will find most useful are:

<div class="maxw-700px px-3 mx-auto mb-6" id="bkmrk-%2Fbin---basic-program"><div class="maxw-700px px-3 mx-auto mb-6"><div class="markdown-content text-black flex-grow mx-auto mb-4 p-4"><div>- <span class="fp-block">/bin</span> - basic programs (ls, cd, cat, etc.)
- <span class="fp-block">/sbin</span> - system programs (fdisk, mkfs, sysctl, etc)
- <span class="fp-block">/etc</span> - configuration files
- <span class="fp-block">/tmp</span> - temporary files (typically deleted on boot)
- <span class="fp-block">/usr/bin</span> - applications (apt, ncat, nmap, etc.)
- <span class="fp-block">/usr/share</span> - application support and data files
