Pseudo-folders are shown in cyberduck when viewing the contents of a bucket.
If a "folder" is selected and deleted, all the files with the path to that "folder" at the beginning of the filename are deleted as expected. But then you get an alert box for an error deleting "." which of course never existed in the first place, as "folders" are faked.
When there are many "folders" to delete, each has to be done singly because of this alert box.
