Adobe Bridge, lost keywords and rebuilding my list

I am recovering from a fatal pc drive crash and have lost so much information, including my master Bridge keyword file. I am now trying to rebuild my keyword list from scratch.

The issue I am having is that my pictures file covers around 20 years worth of photography, by date, so covers hundreds of folders and many hundreds of thousands of images.

The process I have used so far is this …

1. Go to my Master pictures folder
2. View, include all subfolders
3. Refresh

I was told that this would re-build the data from scratch, but having left this running for 24hrs, absolutely nothing changed to my keyword list.

It seems that I have to go through the folders one by one to recover the information, but obviously I dont want to have to do that …. I dont have the time or the patience.

I am looking for an automated process I can go through to recover all of the keywords. Any ideas or suggestions welcome.

Thank you
