Questions answered in these manuals
Why can’t some MP3 songs play on the walkman?
Only MPEG‑1/2 Layer III MP3 files are supported; other MP3 variants are not recognized.
Why does the displayed storage capacity differ from the advertised value?
The walkman’s internal software reserves a small portion of the memory, so the OS shows slightly less than the total capacity.
