Test-FileCatalog
validates whether the hashes contained in a catalog file (.cat) matches the
hashes of the actual files in order to validate their authenticity.
This cmdlet is only supported on Windows.
Test-FileCatalog [-Detailed] [-FilesToSkip <String[]>] [-CatalogFilePath] <String> [[-Path] <String[]>]
[-WhatIf] [-Confirm] [<CommonParameters>]
This cmdlet is only available on the Windows platform.
Test-FileCatalog
validates the authenticity of files by comparing the file hashes of a catalog
file (.cat) with the hashes of actual files on disk. If it detects any mismatches, it returns the
status as ValidationFailed. Users can retrieve all this information by using the -Detailed
parameter. It also displays signing status of catalog in Signature property which is equivalent to
calling Get-AuthenticodeSignature
cmdlet on the catalog file. Users can also skip any file during
validation by using the -FilesToSkip parameter.
This cmdlet is only supported on Windows.

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
You can pipe a DirectoryInfo
object representing the path to the files that need to be validated.
You can pipe a string representing the path to the files that need to be validated.
By default, this cmdlet returns a CatalogValidationStatus object with a value of either Valid
or ValidationFailed
.
When you use the Detailed parameter, the cmdlet returns a CatalogInformation object for each file, which can be used to analyze specific files that may or may not have passed validation, which hashes were expected vs. found, and the algorithm used in the catalog.
This cmdlet is only available on Windows platforms.
