Not all rendered files are getting deleted.

In my the option deleting optical flow files in FCPX in deleting generated library files menu should be added. It would save a lot of time to find the reason why the library is huge, and delete it manually. Why is this feature important, because lets say I am using optical flow, and then I change my mind, like I did in my latest project. After finishing 5 minutes video project, I noticed that my library is huge. 75GB!!!

I thought it was rendered and optimized files, that it was not the case. So looking into Package content I noticed that the optical flow folder was 72GB, in spite that I no longer was using optical flow.

I spoke to the senior advisor and he agreed with me that it would be a great feature to add. He suggested to report to the development team, which I normally do, and unfortunately so far did not get an answer.

That's it,
