I am not sure what 'part' you would like me to take a picture of in the file browser, like the directory you want it to be in. All the others I can do . . .
Without wishing to be patronising, I would have thought it was clear that I would like to see a screendump from your PC file browser (Windows Explorer?) showing the 'new' files
on your Sansa (X:\MUSIC\[artist]\[album] etc, where X is the drive letter of your Sansa)...
...and then the
same directory as viewed through Rockbox's File Browser) Main Menu > Files > MUSIC > [artist] > [album]).
The aim is to demonstrate that the files are actually on the device (as shown on your PC), but that Rockbox cannot apparently see them (as shown using the File Browser)
