Granted that picture doesnt really explain much, but it did get me on the right path[1], so thanks.

    Remember the days when DOS/Windows file name restrictions were a target of mockery? 
    E.g. the sarcastic “C:\ONGRTLNS.W95” full-page newspaper ads Apple ran when Microsoft launched Windows 95. 
    With the iPod Shuffle, Windows’ limitations are now ours, too.
