How to work on WP if the Webspace is pointing to a different Place

Hi there,

i guess im hanging on this…
So i have a Webspace that is pointing to one Folder where is right now running a Website on. In another Folder i installed the WP, for the install process i pointed the URL to that Folder and afterwords to the old one.
Now i thought i could build in WP the Site, let the old one run until im finished, change then the pointer and im good to go. But now im hanging, because i get now access to the Folder where is WP inside because it actually has (obviously) no URL.

Has anone a clue what to do?

Best wishes

Andy
