[galaxy-user] Upload files from filesystem paths

Hi, I have a local galaxy installation. I've created a data library, selected "Upload files from filesystem paths", pasted a path in the "path to upload" window, and I've selected to preserve the directory structure". And the files get imported. How do I now access these files from my application? I don't want to import them into the history as then they lose the directory structure. I can't see where they are physically under the galaxy-dist structure Thanks for any help Neil
