Windows Server : view open files on network shares

In this article, I will explain how to view from a Windows server open shared files / folders.

There are two ways to access open files / folders in either graphical or command-line mode using PowerShell.

PowerShell

List open folders / files:

Get-SmbOpenFile

Result :

FileId       SessionId    Path                      ShareRelativePath ClientComputerName ClientUserName
------       ---------    ----                      ----------------- ------------------ --------------
122675006077 122876330697 C:windowsSYSVOLsysvol                   10.0.0.50          LABAdministrateur

Detail on a file:

Get-SmbOpenFile -FileId <!ID-FICHIER!> | Select-Objet -Property *

Result : 

SmbInstance           : Default
ClientComputerName    : 10.0.0.50
ClientUserName        : LABAdministrateur
ClusterNodeName       :

FileId                : 122675006077

Path                  : C:windowsSYSVOLsysvol
Permissions           : 1048705
ScopeName             : *
SessionId             : 122876330697
ShareRelativePath     :
Signed                : True
PSComputerName        :
CimClass              : ROOT/Microsoft/Windows/SMB : MSFT_SmbOpenFile
CimInstanceProperties : {ClientComputerName, ClientUserName, ClusterNodeName, ContinuouslyAvailable...}
CimSystemProperties   : Microsoft.Management.Infrastructure.CimSystemProperties

Filter the list of open files:

Get-SmbOpenFile | Where-Object -Property ShareRelativePath -Match ".vhdx"

The above command, display only vhdx files
