Hm, here's a question:
When you rename a folder within a bucket (still a bit confused about the meaning of "bucket", but I'll go back to the wiki), does Cyberduck have to "copy" all of the contents of the folder to the "new" folder? I'll have to double-check, but I recall noticing that a simple renaming operation seemed, under-the-hood, to be a "duplicate folder to new location" type thing, which took many times as long to accomplish.
Then, deleting folders: generally it works as I expect, although there seems to be some latency issue that requires me to refresh multiple times to see the directory listing the way I expect.
However, there's one file in particular that I haven't been able to get rid of. If I can't delete a folder or file does that indicate a permissions issue or something, maybe?
Thanks for your help! I believe that my connection was set up properly cause I seem to have full access, apart from these particular behaviors...
