Get SmbOpenFile - PowerShell


Get-SmbOpenFile retrieves a list of opened files on a given SMB share. This command is useful for identifying and managing file access, such as determining which users have opened specific files or which files are currently being accessed.


Get-SmbOpenFile <SharePath> [-Size <Size>] [-Server <ServerName>] [-Credential <PSCredential>] [-Filter <Filter>] [-ComputerName <ComputerName>] [-Verbose | -Debug]


  • -Size: Specifies the count of open files to retrieve.
  • -Server: Specifies the name of the SMB server hosting the share.
  • -Credential: Specifies the credentials to use when connecting to the SMB server.
  • -Filter: Filters the list of open files based on a specific criteria.
  • -ComputerName: Specifies the name of the computer to enumerate open files for.
  • -Verbose: Enables verbose output, displaying detailed information.
  • -Debug: Enables debug logging, helpful for troubleshooting issues.


Example 1: List all open files on a SMB share

Get-SmbOpenFile \\server\share

Example 2: Filter open files based on username

Get-SmbOpenFile \\server\share -Filter "Username -eq 'user1'"

Common Issues

  • Permission Denied: Ensure that the provided credentials have sufficient permissions to access the SMB share.
  • No Open Files Found: The SMB share may not have any open files, or the filter criteria might be too restrictive.


Get-SmbOpenFile can be integrated with other PowerShell commands for advanced tasks, such as:

  • Exporting Open Files: Combining with Export-Csv to export open file information to a CSV file.
  • Managing File Access: Use with Stop-SmbOpenFile to close specific open files.
  • Get-SmbConnection: Retrieves information about active SMB connections.
  • Stop-SmbOpenFile: Closes a specified open file on an SMB share.
