I had to move my Launchbox installation to a secondary drive, so I copied the files in their entirety to the second drive, and tried to install launchbox again in the location of the moved files. Things have not worked out as hoped. But I don't want to have to re-download all of the box art as I need my bandwidth for other things. What do I archive from the old installation to keep all of the box art that was already downloaded, so I can move it to a new clean install?
