Can DRAN-VIEW 6 save files in a DRAN-VIEW 5 format?
No, not directly. The only way to make DRAN-VIEW 5 read a file created by DRAN-VIEW 6 is by going through the PQDIF format. If DRAN-VIEW 6 is equipped with the PQDIF Writer option you may save to PQDIF, and then a DRAN-VIEW 5 equipped with the BMI/Signature System option (allowing reading PQDIF files) will read the file.
