Some s3 service's capability of directory

[cndonnie]

In some s3 capable service such as minio , directory such as root / , not recognized as directory by api, so ftp client can't list directory. In this case, could we just treat path name with suffix / as directory? I had try it without thoughtful, it seams well.
