Well, I thought this subject had been put to bed and didn't intend to say more. I finally had time to look at the actual files and found that everyone is sorta' right. The KN7000 supports only 8 characters for the actual file names. The file name for each file on the SD card uses a numbering system that represents the location of the file on the card. Within that file there is a 16 character string variable that we are allowed to fill that contains the name that we want to be displayed. The software selects out that string and displays it instead of the file name. That explains why you can't load or save a long file name to or from the SD Card to an external device. The KN7000 can only "see" the 8 digit number name in the load or save process. Yes you can backup and restore the "long" file name but it is saved at the backup location with the 8 digit name. That also explains why the floppy system still uses the old 6 character name with the two characters used for the numbers 01 thru 20.
