Honor Magic 5 Pro, Magic OS 9.0, Android 15
I have one of these gadgets

Using standard Android "Files" I can copy SD Card -> Phone then Phone -> USB. But if I try to copy SD Card -> USB, which is what I want to do, I get "Cannot find target path" error.
I can copy USB -> USB, USB -> SD Card, USB -> Phone, SD card -> Phone, Phone -> both SD card and USB but not SD -> USB. Doesn't make sense. I haven't tried the Micro SD card slot because I don't have any cards.
Anyone any ideas?
TIA, Bob
