General Info

  • If the extension in the form .??_ the file is probably a compressed file and part of an install routine.
  • If the file is an audio file with any three-character extension it may be a dictation file. The file could likewise be a dictation file in TrueSpeech format. Use Windows Sound Recorder and/or Media Player to play these back.
