Q: “Whenever I open an audio file in Spark, it creates an additional file, with the same name, but with the extension “.ovw”. What is this file for? Can I delete this file?”
A: The .ovw file is a waveform overview file that SPARK generates for its own use. It enables SPARK to quickly scroll within the file and allows subsequent openings of that file to happen much more quickly. You can delete it, but re-opening the audio file in SPARK will then take longer. If SPARK does not find an .ovw file, SPARK will automatically create a new .ovw file when it is opened.
