Complete Modern C++ - Introduction to Filesystem Library (C++17)

The video introduces the file system library in C-17, explaining its experimental status and basic functionalities. It covers the path class, which represents file system paths and provides useful functions for path manipulation. The video also discusses the directory iterator, which allows iteration over directory contents. The instructor advises against using the library in production code until the C-17 specification is finalized.

Describe how the directory iterator works in the file system library.

Why should developers avoid using the file system library in production code until the C-17 specification is released?
