I have Adobe Bridge 2020 on both a PC and a laptop using Windows 10. I only use one machine at a time.
All my images are on a 1tb external drive.
From Bridge on my PC I relocated the cache to a folder on the external drive to save computer space. This set up works fine but if I attach the external drive to my laptop and open Bridge I want to be able to access the cache on the external drive but don't seem to be able to do it.
