WAV file > 2GB

[MINORISUKE]

Thank you, Simon and rompolompo.
I used dBpoweramp to convert FLAC into WAV, but the WAV file was still invisible. There was neither a warning nor an error message during the conversion.
I am wondering, because the WAV files of other 4 movements in the same folder smaller than 2GB came up and could be played back.
Only the 5th movement in WAV exceeds 2GB.
