Everyone,
 
Does anyone know how I can move the rapture file data to an external drive?

I just moved my Rapture Pro multisamples to a different folder on a different hard drive.  What I did was to run the Rapture Pro installer again, and when it prompts for the location of the multisamples, change the location to the new hard drive and folder.  It worked fine for my Rapture Pro, I don't know if it is the same for Rapture or not, but worth giving it a try.
 
Good luck.

Unfortunately re-installing rapture did not prompt me to install into a different folder.  How do you  get it to prompt you to install it's data into another folder?

It involves a registry hack and it differs depending on the o/s. I don't have the details to hand, but try googling it.
