this topic is for sure not new, but the asset system of the Unreal Engine really needs to be reworked. It’s inacceptable that deleting or renaming assets takes minutes. It’s absolutely impossible to reorganize the assets in a somewhat larger project unless you want to spend days with it.
I don’t know what the Unreal Engine makes in the background, but I am sure that sometimes there is a timer which says “rename only 1 asset per second” as it renames exactly every second one asset. This only says me that the asset system is really not well thought out - and optimizing it could for sure minimize the time needed for renaming/deleting/reorganizing assets from minutes and seconds to milliseconds.
The asset system absolutely does not go with the modernity of the Unreal Engine and to rework it should be on one of the first places on the to-do-list. Or in other words: It’s really annoying that such a modern engine has such a extremely bad asset system.
