// A file finding application showing how to use the filesystem wrapper in the file API using C++ 2017.

/*
TODO:
 * Function for getting EntryType from a path.
 * Implement file_getParent, getting the parent folder or root path, so that it's easy to iterate the other way.
 * Something for listing root paths, so that systems with more than one system root can have a listbox with drives to select in file explorers.
 * Wrap file_getPermissions
 * Wrap file_moveAndRename (over std::filesystem::rename)
 * Wrap copy (over std::filesystem::copy)
