Fails to delete directory

[drn5910]

When using this SFTP adapter I cannot delete a directory on a server, I've debugged it and the following SFTP error is generated in the SFTP library you use: NET_SFTP_STATUS_FILE_IS_A_DIRECTORY: Specified file is a directory.

After further investigation, it seems you are calling delete in your deleteDir method. I believe this should be rmdir to remove a directory.
