System Volume Information -> Catalog.wci = 8GB and climbing

Windows SBS Server 2003 32bit

we see in system volume information on the C drive there is a file\folder called Catalog.wci.  It is presently 8GB and doing its best to fill up our  C drive.  How can we tame this beast?

i actually turned off Shadow Copy on C:\ drive.   and the files remain.  

here is the result of vssadmin list shadowstorage:

C:\Documents and Settings\Administrator.domain>vssadmin list shadowstorage
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001 Microsoft Corp.

Shadow Copy Storage association
   For volume: (D:)\\?\Volume{ID}\
   Shadow Copy Storage volume: (D:)\\?\Volume{ID}\
   Used Shadow Copy Storage space: 12.984 GB
   Allocated Shadow Copy Storage space: 13.262 GB
   Maximum Shadow Copy Storage space: 43.931 GB

So nothing mentioned about the C drive.  Googling this issue does not point to Shadow Copy, but to IIS Indexing.  Any ideas?

c:\system volume information\catalog.wci = currently 9.7GB

if i look at Computer Management -> Services and Apps -> Indexing Service -> the "System" Catalog in location "C:\system volume information" is 5824MB

shard26Author Commented:
we stopped the indexing service via computer mgmt and are now moving a 3.9GB .ci file over to our D drive.  We also removed all the directories that the "system" catalog was indexing.
