How it works...

When we want to find files in a directory, the structure of the directory and the order its entries, including subdirectories, are visited in is probably not important. Therefore, we can use the recursive_directory_iterator to iterate through the entries.

The function , find_files(), takes two arguments: a path and a function wrapper that is used to select the entries that should be returned. The return type is a vector of filesystem::path though, alternatively, it could also be a vector of filesystem::directory_entry. The recursive directory iterator used in this example does not follow symbolic links, returning the link itself and not the target. This behavior can be changed, using a constructor overload that has an argument ...
