Does Avast One use Persistent/Transient Cache to save time while doing Deep Scan, Quick Scan or Custom Scans?

In Avast One, does File Shield add safe files to Persistent/Transient Cache? And later does File Shield exclude scanning these files inside these Caches to save time?

Afaik, yes. Engine/Functionality is the same as in “old” products.
