The ;Boost.Filesystem is a part of C++17. All the stuff in C++17 is located in a single header file <filesystem> in namespace std::filesystem. The standard library version of filesystem differs slightly from the Boost version, mostly by using scoped enumerations (enum class) where Boost.Filesystem was using just unscoped enum.
There is a class ; directory_entry. That class provides caching of filesystem information, so if you work a lot with filesystem and query different information, try using directory_entry for a better performance.
Just like in the case of other Boost libraries, Boost.Filesystem works on pre-C++17 compilers and even on a pre-C++11 compilers.
