Hi
In addition to what tohlz said, you can search across multiple files at once
to find out which contain the key phrase:
1. In windows explorer right click on the folder or drive that contains the
presentations and select 'search...'
2. In the 'All or part of the file name' box put *.ppt (you will need to
redo the search with *.pps if you have some of those)
3. In the 'a word or phrase on the file' box type your specific text
4. Click 'search'
5. Go and make a cup of tea (the search will take a while!)
I use XP - if you use something different or can't see the boxes press F1
while you have the search dialogue box open. Hope that helps
