not compatible with some of the well known scripts like sponsorblock (https://github.com/po5/mpv_sponsorblock) or quality-menu (https://github.com/christoph-heinrich/mpv-quality-menu)

By far for Windows the best solution. The registry handler method is clean and very well to edit to your directory paths. Perfect solution for my use case.

Perfect! This method is the best.

Works perfectly, you are a genius!

Very useful thing. Thank you!
