When starting to download a S3 directory full of nested subdirectories and files, the download starts with a long hang. For a directory with size 1G, the hanging can be as long as 10 minutes. Downloading the directory with aws_cli or other file transfer tools didn't encounter the same issue.

We tried both Windows 10 and macOS 11 and experienced the same issue.

Let me know if more information is needed to reproduce the issue.

We are reading remote file attributes prior a file transfer which causes the delay in the Prepare… status.

Is there a way to turn off the "pre-scanning" somewhere? It would be nice if it can start the download recursively just like aws-cli by options.

If this option is not available and you think this is a good feature to add in, let me know. I can look over and push an MR about this.

There is currently no way to turn off or work around the pre-scanning process.

Well, i have just enjoyed waiting nearly 2 days while Cyberduck is 'preparing' nearly 4tb of files. So yes, skipping the prepare phase would definitely be a time saver. Please think about adding this feature. For the love of time!
