SWF in the core package

Been using MODX for quite a few years and have just noticed that within the core package there are a number of .swf files. What are they doing there? Do they server any current purpose. I would have thought that any remnants of flash would have been removed from MODX many years ago.

Hope everyone is doing well considering the current environment.

They will be removed in MODX 3.

Thought so. Thanks for the clarification. Are they used in MODX 2.7.3?
