Managing the filesystem

Your applications will often need to perform input and output with files and directories in different environments. The System and System.IO namespaces contain classes for this purpose.

Handling cross-platform environments and filesystems

Let's explore how to handle cross-platform environments like the differences between Windows and Linux or macOS.

1. Create a new console application named WorkingWithFileSystems in a folder named Chapter09.
2. Save the workspace as Chapter09 and add WorkingWithFileSystems to it.
3. Import the System.IO namespace, and statically import the System.Console, System.IO.Directory, System.Environment, and System.IO.Path types, as shown in the following code:

   using System.IO; // types for managing the filesystem
   using static System.Console;
   using static System.IO.Directory;
   using static System.IO.Path;
   using static System.Environment;

   Paths are different for Windows, macOS, and Linux, so we will start by exploring...
