How to force Unity to clear its Library/Artifacts folder via script (2019.4.1f1)?

We are working on a project where we need to open something in the Unity editor, process it, and then delete the files. We're finding however that - even when using AssetDatabase.DeleteAsset - the Library cache for those files stick around. So after an hour of running, we've got 5gb+ of cached data in Library/Artifacts. We need a way to manually tell Unity "These files are no longer there, you can remove their data from Library". Spent the morning reading Unity documentation and searching forums and Google to no avail.

Could someone please point me in the direction of who we can tell Unity to clear its Library/Artifacts folder?

Thank you!

 

When I work with problematic repos like this I usually just make a little

zap

shell script that I can poke whenever things get out of hand and it blows away areas that keep growing.

SUPER low-tech I know, but works 100% of the time.

 

What happens if you just...

Directory.Delete

the Library folder? Or is that too nuclear?

 

Does wiping the Library, e.g. with

Directory.Delete

, have any adverse side effects if you do it from code while the editor is running?

At the very least, it would cause a recompile of all source, right?
