To translate the criptic message:
In the ini file, there is an entry called: "/apps/er/sys/ctb/showdir" if it has the value "sdcard" the code suggests that you will see folders.
Note1: The ini file is located in the DR1000 on the SD card under /System/dr1000.ini, so probably it will be located at a simular place on the DR800.
Note2: take a copy of the original DRxxxx.ini
Note3: The drxxxx.ini file is read during power-up, so power-down the DR when changing it.
Do this at your own risk!
