Please share a sample FLAC and WAV file with [url=https://www.mediamonkey.com/support]Support[/url], they're likely corrupted.

You'll need to upload to a cloud service like OneDrive and include a link to your shared folder in the Support Ticket.

I re-scanned my library on MM5.04.2693 and found that 400 files were not added to database. They were all either Flac or Wav files. Message was "unable to read file".
