Conversion of b1 files to rar file format

You can certainly decompress B1 archives (.b1) and repack the data to  RAR format. Unfortunately, no program can directly perform b1 to rar conversion or repacking, so you have to first use the B1 Archiver to decompress the .b1 files and then compress them to RAR format.
