I have a SharePoint 2007 front end server and the C: drive space started being consumed by something. I looked into it and some of the *.ci files from the C:\Program Files\Microsoft Office Servers\12.0\Data\Office Server\Applications\(guid)\Projects\Portal_Content\Indexer\CiFiles directory are huge, some ranging from from 200mb to 500mb. I think they are content index files.
Can I get rid of these files?
What are they tied to and why should I care about them?
