Cant create files or directory on Bitnami/Magento stack

Hi,
Ive installed the bitnami/magento stack and all has gone well.
Ive enabled ssh and can sftp to the directory using the default bitnami user but I cant create any new directories. I try to update to 777 but it reverts back.
I tried to give user:bitnami r+w on the directory but it crashed the site and i had to re-install the server.

I assume bitnami is not the root user for sftp but I cant work out what user to log in to sftp with other then the default bitnami/bitnami

Any assistance would be great before I break the stack again.

here is the output from FileZilla
