FTP access to installed app's on Ready NAS 102

Hi.

I have a ReadyNAS 2Bay 102. First i was using it as Storage only, but now i like to use it to prepare Websites in my own Network before uploading them to the Webservers.

Like i did it before on a local WAMP installation. I'v prepared my NAS, Factory-Restore, installed PHP, myAdmin, the PHP info, MySQL and Drupal.

FTP and SSH is enabled. Using WinSCP and when connecting, end up in the Root direcory from the NAS.

So far so good BUT

The only folders visible in the root are the ones from Shares.

And there i cant see any of the f.e. Drupal folders or from any other app i have installed.

So i cant give them free for access.

ATM i am using Win10, so no way for a Linux Terminal to try it that way.

And i need to have this access for fully controll of f.e. Drupal Directory.

I even can't edit php.ini or any other config files.

Still working on it, searching the Web and u'r community to find a way, but any help are wellcome.

THX a lot
