Nov 23, 2012 On our old server that is running win2k3 r2 I would always use filesvr.exe which was found at c:windowssystem32. It doesn't look like this exists in sever 2012. Can someone tell me how can view what files users have open? Nate Hi, You may view open files using Computer Management (compmgmt.msc) by selecting System ToolsShared FoldersOpen Files.
Windows file server administrators often have to force close the shared files opened by users. This task appears when several users work with the same file simultaneously. Often, if the software is not working properly or the session is terminated incorrectly by the user, it often happens that files in the shared folder are still open (and locked), and other users can’t make changes to them. In this article we’ll show how to get the list of open files on the file server (running Windows Server 2012 R2), find out which user locked a file on a shared folder and close (reset) these file sessions.
How to View the List of Open Files on Windows Server
You can get the list of files opened by users on Windows file server using built-in Computer Management (compmgmt.msc) graphic console.
Open the Computer Management snap-in on your file server (or connect to the server remotely from the management console running on your computer) and go to System Tools -> Shared Folders -> Open files. The list of files opened on the remote server is displayed on the right side of the window. The list contains the local path to a file, the name of the user account that opens the file, the number of locks and the mode in which the file is opened (Read or Write+Read).
You can get the same list of open files using the built-in console tool – Openfiles. For example, using the following command you can get Session ID, user name and full local path to the open file:
Find Open Files Windows ServerOpenfiles /Query /fo csv |more
If a user accessed a folder or a file in the shared folder on the server remotely using the SBM protocol, a new session that determines the connection is created for the user. User connections are managed using through session IDs.
You can run the same command remotely. For example, you need to show a list of open files on lon-fs01 file server:
Openfiles /Query /s lon-fs01 /fo csv
The Openfiles command has another useful feature to view the list of locally opened files. To use it, enable Maintain Objects List option using the command:
openfiles /local on , and restart your server. After that, the files opened by local processes will be added to the list of open files (it is recommended to use this mode only for debugging purposes, since it can negatively affect the performance of your server).
How to Detect a User Who Opened a File
To detect a user who opened (locked) filename.docx file on the server, run this command:
Openfiles /Query /s lon-fs01 /fo csv | find /i 'filename.docx'
Open File Shares Windows Server
/i key is used to make case-insensitive file search.
Of course, you can specify only a part of the file name. For example, you need to know who opened an XLSX file containing “salereport” in its name, so use the following pipe:
Openfiles /Query /s lon-fs01 /fo csv | find /i 'salereport'| find /i 'xlsx'
Of course you can find this file in the Computer Management GUI, but it’s less convenient (this console doesn’t provide search feature).
How to Force Close an Open Shared File
To close an open file, find it in the list of files in Open File section and select Close Open File in the context menu.
If there are hundreds of open files on your file server, it won’t be easy to find the specific file in the console. It is more convenient to use Openfiles tool. As we have already told, it returns the session ID of the open file. Using this session ID you can force close the file by resetting the connection. Find the ID of the file you need:
Openfiles /Query /s lon-fs01 /fo csv | find /i 'farm'| find /i '.xlsx'
Disconnect the user from file using the received ID:
Openfiles /Disconnect /s lon-fs01 /ID 617909089
How to Close Open Files Remotely Using PowerShell
New cmdlets to manage shares and files on an SMB server appeared in PowerShell for Windows Server 2012 / Windows 8. These cmdlets can be used to remotely reset connections to an open file.
You can get the list of open files using Get-SMBOpenFile, and close a file (reset a connection) using Close-SmbOpenFile.
So, let’s connect to a remote server:

$sessn = New-CIMSession –Computername lon-fs01
Find and close the open file pubs.docx using a single command:
Get-SMBOpenFile -CIMSession $sessn | where {$_.Path –like '*pubs.docx'} | Close-SMBOpenFile -CIMSession $sessn
Confirm closing of the file by pressing Y.
To remove the confirmation of force closing a file on a file server, use -Force key.
These commands can be used, for example, to close all files opened by a certain user (a user went home and didn’t release the files). For example, to reset all file sessions of the user mjenny, run this command:
Get-SMBOpenFile -CIMSession $sessn | where {$_.ClientUserName –like '*mjenny*'}|Close-SMBOpenFile -CIMSession $sessn
