Automatically compress/uncompress files preserving streams and Macintosh files integrity. 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). Also a Windows NT/W2K service.
