Thomas,
You need to select the parent folder, then, from the tols menu>Cache>Build Cache for subfolders
I don't think there's any way to tell Bridge to always build for any subfolders any time t sees some.

Peter i selected the parent folder then went to Tools>Cache but there was no option for "build cache for subfolders", the only options it gave in the flyout menu was " Build and export cache" and "Purge cache from folder XXXXX". Am i missing something?
