Windows Server : view open files on network shares

Windows Server 2019

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.


List open folders / files:

------       ---------    ----                      ----------------- ------------------ --------------
122675006077 122876330697 C:windowsSYSVOLsysvol                   LABAdministrateur

Detail on a file:

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

Result :

FileId                : 122675006077

ScopeName             : *
SessionId             : 122876330697
ShareRelativePath     :
