I’m able to delete files in this way, provided that they legitimately contain data. However…
if I forget to arm any tracks before recording, the file created can neither be loaded (I get a “Failed to load file!” error) nor deleted (nothing happens. unless I’ve previously loaded a different file, at which point that file gets deleted). I am also unable to rename it.
I can probably delete the file by transferring the SD card to my computer. Have not tried yet.
But, yeah. I have three of those cluttering the directory now. They probably won’t be the last.
