Description

The Repair-FileIntegrity cmdlet repairs a corrupted file on an NTFS file system volume or a Resilient File System (ReFS) volume. For the cmdlet to repair a file, the file must be on a storage volume that provides redundancy, and the file must have integrity turned on. This cmdlet does not repair corrupted file metadata.

Examples

Example 1: Repair a file 

PS C:\>Repair-FileIntegrity -FileName 'H:\Temp\Text Document.txt'

This command repairs a file. Because the repair proceeds without error, the cmdlet does not display any message.

Example 2: Attempt to repair a file that cannot be repaired 

PS C:\>Repair-FileIntegrity -FileName 'J:\Temp\Text Document.txt'
Repair-FileIntegrity : The storage device does not provide redundancy.

This command attempts to repair a file. In this example, the cmdlet cannot repair the file and therefore displays an explanation.

Required Parameters

-FileName

Specifies a file name. The cmdlet attempts to repair the file that you specify.

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
