How to check and filter open files in Microsoft Windows for a user

There are multiple methods for examining Windows file shares and accessing files within them. A user-friendly approach is through the Microsoft Graphical User Interface (GUI). Simply enter ‘compmgmt.msc’ in the search bar to launch the Computer Management App and explore file shares and open files effortlessly

After launching the console, navigate to the ‘Shared Folder’ section where you’ll find the ‘Open Files’ folder. Clicking on ‘Open Files’ reveals a comprehensive list on the right pane, displaying all currently opened files

PowerShell also can be used to see open files.
