I have a SharePoint 2007 farm that has an index server and two query servers. The query servers are also the WFE's. I am running out of space on my index server. I have cleaned up all that I can from the drive the index files are located on. Now I am looking at the index files and I am curious if I can delete files older than the last full crawl. The last full crawl completed on 9/8 and I see a lot of files that are older than this. Can I delete all of the files older than 9/8 without affecting search? Currently my index directory is at 58GB where the query servers only have 18GB for the index. So I am thinking I have 40GB of junk. Thanks

40gb, it's your crawl index database log I'm sure unless you have a stupidly large sharepoint installation.

This has been answered before so here is how to reduce all the empty space.

If you happen to have a massive installation I would look at some more storage space and look into spreading your index over a couple of dedicated drives. (But I doubt it is this)

It wasnt the search database but the index files that were taking up all the space. It finally ended up cleaning itself up once it got to a certain point, not sure how it decided where that point was. Now I have 38GB back. Thanks for the link. – Cory Sep 10 '12 at 14:25
