I am getting a new PC with Win 7 64 bit on it. My old PC has Win 7 32 bit. My question is, after I download BaseCamp to my new PC, can I just transfer my existing GPSFiledepot maps from the old PC to the new PC, or would it be best to just download the maps I want onto the new PC, so BaseCamp knows exactly where they are? I am afraid that if I transfer my existing maps from old PC to new PC, BaseCamp on the new PC won't know where to look for them. Any advice would be appreciated. I have read about using My Trails on Win 7 64 bit, so I have that trick in my pocket already, if needed.
