Scanning and diffing takes a long time for large directories

[wcerfgba]

Hi,

I am trying to copy a large folder (several GiB with many thousands of files) and I'm stuck on INFO:root:Scanning and diffing... for a long time. Is there a way I can skip this and just delete/overwrite files by name?

Thanks!

What does "just delete/overwrite files by name" mean?

I have found that when there are a large number of small files, PerformCopies pull files take much longer than ScanAndDiff. 20,000 files would take about two or three hours.
