Deleting folder almost freezes program
I was trying to delete InfinityBladeEffects folder from the engine. First I shut down the engine from Task Manager cause I thought it froze. But on the second try I left it to go for several minutes, and only then became responsive again, and started slowly deleting assets one by one.
What causes this huge unresponsiveness for a long time, and why is deleting files so slow? (even if it's a big folder)
(Not sure if it should be in the Bug Reports topic or where)
I believe that the reason your editor is hanging when you're attempting to delete that folder is definitely due to the size of the folder and the files contained within. I'd recommend deleting the folder from Windows Explorer using your project directory in order to avoid the in-editor hang. This goes for all large folder removal.
Let me know if you have further questions regarding this.
Have a great day

I think the official answer should be rephrased to:
The reason why deletion is so slow in UE4 is that it loads all the assets you are deleting to check for their dependencies across your entire project.
