MacPAR deLuxe is a utility program that runs on Macintosh OSX. It is useful to you if you upload and download binary files to and from Internet newsgroups.It's main functions are:
* Ensure error-free transport of the data by means of so called "par" and "par2" files;
* Unpack data from a RAR archive (most of the files in newsgroups are compressed with rar);
* Automatically start an external program (such as Stuffit Expander) to process downloaded files.
