Introduction
Here's a brief look at what we'll tackle in this section
Filesystem
Since early versions, in the Standard Library, there was an option to work with files. Through streams - like fstream you can open files, read data, write bytes and perform many other operations. However, what was missing is an ability to work with the filesystem as a whole. For example, in C++14 you had to use some third party libraries to iterate over directories, compose paths, delete directories or read file permissions. Now, with C++17 we made a big step forward. We can now leveragestd::filesystem component!
In this chapter you’ll learn:
- How
std::filesystemgot into the Standard - What are the basic types and operations
- How you can work with the paths
- How to handle errors in
std::filesystem - How to iterate over a directory
- How to create new directories and files
Let’s get started with the overview of filesystem.
