Some questions about support for AWS Glacier:

1. If I change the storage class of a subfolder to Glacier Flexible Retrieval, "Long-lived archive data accessed once a year with retrieval of minutes to hours," will there be a potential delay on getting the file listing for the folder or only for retrieval of individual files?

2. If there is a delay on the subfolder, is there also a delay on the parent folder?

3. If there is little to no delay, what is the oldest version of CloudBerry Explorer to have sufficient support for Glacier? I am running 5.6.1.2 . I need to know what to recommend to a couple of family members.

My use case is a single S3 bucket in oregon with 109775 files, 399GB data. I was considering leaving some folders in Standard class but putting a lifecycle rule on others.



Thank you.
