Rarissimo is a file utility to automatically compress and/or uncompress files, companion for the award winning compression program WinRAR. Distinguishable from other compression solutions by its ability to fully preserve NTFS alternate streams. This feature provides automatic compression/uncompression for Macintosh files stored on NT volumes preserving their filenames and peculiar structures - it means for example that you can use Rarissimo to send and receive Macintosh files using any standard FTP process (and not only Mac-based programs).

DataCompression.info user Marie M. said: This utility is very specialized so not easy to find. It is a great help to transfer Mac files without a special Mac ftp utility.
