It is supported in (as far as I know) all programming solutions, I’m not sure if we support sub-directories yet, need to check on that.
In VCS we have some simplified methods but you can also use standard file IO such as
// create a file with long filename
std::ofstream ofs ("a_long_filename_debug.txt", std::ofstream::out);
ofs << "lorem ipsum\r\n";
ofs << "this was a test of a file with long file name\r\n";
ofs.close();
