Repair-FileIntegrity

Repairs a corrupted file on an NTFS or ReFS volume.

Syntax

Parameter Set: Repair2
Repair-FileIntegrity [-FileName] <String> [-AsJob] [-CimSession <CimSession[]> ] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed 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.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-ThrottleLimit<Int32>

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.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • System.IO.FileInfo

    To obtain a FileInfo object, use the Get-Item cmdlet for a specified file name. The cmdlet uses the FullName property as the value of the FileName parameter.


  • System.IO.DirectoryInfo

    To obtain a DirectoryInfo object, use Get-Item for a specified directory name. The cmdlet uses the FullName property as the value of the FileName parameter.


Outputs

The output type is the type of the objects that the cmdlet emits.

  • This cmdlet generates no output.


Examples

Example 1: Repair a file

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


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

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

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


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