Server document and settings folder getting too large

[Seth]

We are having an issue with our vault server. The vault server has a 10 gig system drive (C:\), and the drive keeps filling up. I saw a post in here about developers complaining about the cache in the Documents and Settings folder, and I see that the server's NetworkService profile has a rather large set of files under C:\Documents and Settings\NetworkService\Application Data\SourceGear\Vault_1\

Is it OK to remove these files? Is there a way to automatically remove the files or prevent the files from going in there?

Thanks
