Sub folder should be deleted on a jump host if there are still files/folders inside that directory

It appears that there are issues when using the recursive option and a Jump Host.
Upon transferring the files from the Remote host to the jump host. SOS FTP successfully transfer the files again from the jump host to the internal sosftp machine.
However, during the cleanup process, SOS FTP attempts to delete the temporary files created on the jump host. But when recursive mode is used, it fails to delete the temp folders.
The reason for this is because sos ftp appears to attempt to delete the sub-folder when there is still files/folders inside that directory.

It works for JADE.
It will not fix for SOSFTP
