A Sony digital voice file is stored in the DVF format with the .dvf extension. These files are used by Sony IC audio recorders like ICD-BP150 and ICD-BP100. They are encoded with proprietary compression.
If the system is under heavy load, it may not handle the program to open DVF files. In this case, close other applications. Ensure you have the latest drivers and updates installed. Up-to-date system and drivers make your computer more secure and may solve DVF file problems affecting older software versions.
Below are tips on how to open DVF files and programs that support them:
DVF file extension is used for Sony’s proprietary compressed voice format commonly used by Sony dictation recorders.
If you get “Can’t Open DVF Files” when loading a DVF file, it likely means Windows Media Player is not installed. The OS won’t know what to do with the DVF file, so double-clicking won’t work.
You can convert DVF files to standard .WAV format using Sony’s digital voice editor.
To fix problems opening .DVF files, update the application you normally use to open them. Only the latest version supports the current DVF format. You may also need to check the DVF file for viruses.
