Getting ready

For this recipe, we will consider most of the examples using Windows paths. In the accompanying code, all examples have both Windows and POSIX alternatives.

The filesystem library is available in the std::filesystem namespace in the <filesystem> header. To simplify code, we will use the following namespace alias in all examples:

    namespace fs = std::filesystem;

At the time of writing this book all major compilers provide an implementation of the library, although it is considered to be still experimental and therefore provided in a namespace with this name. Because of that, the actual namespace for the library is std::experimental::filesystem and the actual header for GCC and Clang is <experimental/filesystem>.
