Thanks. I have the latest software so there is nothing to update.
Maybe I will look at the list as “garbage in, garbage out”.
I have always used the computer when SanDisk is attached as a usb to download all voice files.
So, since I know that the directory will always be empty, I can just ignore the garbage.
It is clear that there is a bug, but the device is too old to fix.
Thanks for letting me know that at least I have the best software that I can get.
