You can use the ""hardlink shell ext"" tool to make the junctions/symlinks (google for it): Or the usual command line tools. The boost::is_directory(target) returns false on this junction. I used this Junction technique to move c:\Users\Me\AppData\Local\Temp to another disk, and as a consequence, temp_directory_path() will always fail because that host path is not treated as a directory. ie the line in temp_directory_path(): {{{ if ((ec&&!is_directory(p, *ec))||(!ec&&!is_directory(p))) }}} cheers, Paul " Bugs closed Boost 1.57.0 filesystem Boost 1.53.0 Problem fixed
