HDR10+ Extract Broken?

[mrdav1]

I am running FastFlix 5.1.0 on Windows 10 and when I try to extract HDR10+ metadata the following error occurs:

This has worked OK in the past.

Please help.

Update: I managed to get it to work by doing some housekeeping. I deleted hundreds of empty folders in "D:\Users\Maddie\AppData\Roaming\FastFlix\" (I guess they're left for previous encodes?) and now it all works OK.

Thanks for the update, I will see what I can do for better cleanup!

That would be greatly appreciated. I've just found that "...\AppData\Roaming\FastFlix\queue_extras" contains over 15,000 files equalling 2TB of old metadata!

Automatic cleanup now in 5.2.0!
