Computers organize their files using a tree-like structure known as a file system.
Linux has a single file tree system, which starts with the root directory (/). On a Windows, the "root" would be something like C:\.
The following image shows what a Linux File System would look like.
In Linux, almost everything is represented as a file (or directory) on the File System. This includes USB devices and hard disks, which are stored under /dev.
A filename can contain uppercase or lowercase letters, numbers and most punctuation characters. Note that filenames are case sensitive!
Some files begin with a dot (.) and are used for configuration settings. Others can end with a tilden (~), denoting that it is a backup file. Furthermore, we'll see how we can use ? and * to denote special cases when we learn about wildcards and globbing. Although you can name your files with these symbols, it's highly not recommended.
You can check to see where you are along this file system with the
pwd command (short for "print working directory").
Here, we can see that we are in our FunStuff directory, which is within our Dropbox folder.
