The catalog is physically stored in a user-specified location. A directory named Catalog.wci is created there. Index Server creates a number of files in this directory, including:
| File | Purpose |
|---|---|
000nnnn.prp |
Holds cached properties. The name is the version of the property cache. Each modification to the property-cache schema increments this number by one. |
0001nnnn.ci |
Shadow and master indexes. Each index has a unique number nnnn. |
0001nnnn.dir |
Directory used to quickly search the similarly named shadow index or master index. |
cicat.hsh |
Quickly converts a path into an internal identifier used throughout the index. |
CiCL0001.* |
Contains a log of files that need to be filtered. |
CiFLnnnn.* |
Maps documents to the most recent index for a given document. |
CiPS0000.* |
Describes the record format of the property cache. |
CiPT0000.* |
Maps ActiveX property descriptors to internal identifier. |
CiSL0001.* |
Contains a log of in-use files that need to be filtered. |
CiSP0000.* |
Contains a list of physical scopes covered by this index. |
CiST0000.* |
Maps security Access Control Lists (ACLs) to internal identifier. |
CiVP0000.* |
Contains a mapping between physical and virtual paths. |
Index.* |
Master list of indexes. |
Propstor.bkp |
Backs up portions of the property cache held in memory. See also Main Registry Parameters page. |
The Catalog.wci directory, and everything under it, will not be indexed by Index Server even if it is accessible through a virtual root of the Web site.
