Catalog File Validation

  • Article

Applies To: Windows Server 2008 R2

The catalog files are comprised of multiple files that store file and page hashes used to validate the integrity of  system and non-Microsoft files. Each catalog (.cat file) has a digital signature that is used to validate the integrity of the contents stored within that file. If the digital signature on a system catalog file is corrupt, all of the file and page hashes stored in that file will be considered not valid.

Note: Some Windows boot drivers have the page hash and digital signature embedded in the file itself and do not require a catalog file to validate the digital signature.
