OK, so the long and short of this feature of Adobe Bridge is, it works.
Since I manage a library used by a couple of dozen users, I never use this feature since it can't be shared. But I recently upgraded my Windows machine to Bridge 6.2 and experienced a somewhat troubling when I went to index a copy of the image library I had on an external hard drive.
A few weeks back I uploaded a complete copy of our image library onto an external hard drive, which included nearly 300k of photos taking up some 1.8 tbs of space. I chose to index this external drive copy of the library using the "Prefer Embedded" rather than "Always High Quality” in generating the metadata t speed up the caching process and discovered soon after that the cache was gone, or rather it had not indexed properly. Either way, no search results were coming up.Whatever it was, I was faced with how to resolve this potentially disastrous issue.
So, since I was using the copy of the library I had on an external drive I thought why not try the "Export Cache to Folders" feature? After all, I didn’t need to rebuild the cache on my local machine since I was the only one accessing the external drive.
I selected the Image Library at the topmost level and chose “Export Cache to Folders.” After about 36 hours it had completely built a cache file in each and every one of 164 folders. As a result, searching is quick and spot on. And I don’t have to rely on the nuances of Bridge’s own cache on the machine itself.
One caveat, though: I don’t know what the consequences would be if you moved the image library to a new drive. Would Bridge still read the cache in each folder? My guess is it shouldn’t make a difference and Adobe claims it should still work fine. Still, I’ll have to test that out, but using a much smaller and more manageable sample.
For the moment, however, if you’re the only one using your image library use the “Export Cache to Folders” feature.
