要查看Windows網(wǎng)絡(luò)共享中哪些文件被打開(kāi)，需使用計(jì)算機(jī)管理中的共享文件夾功能，具體步驟為：1. 按Win R輸入compmgmt.msc打開(kāi)計(jì)算機(jī)管理；2. 展開(kāi)系統(tǒng)工具下的共享文件夾；3. 點(diǎn)擊“打開(kāi)的文件”查看當(dāng)前通過(guò)網(wǎng)絡(luò)訪問(wèn)的文件列表，包括文件路徑、用戶、鎖數(shù)量和打開(kāi)模式；4. 可右鍵關(guān)閉特定文件以解除鎖定，但需注意可能導(dǎo)致用戶未保存數(shù)據(jù)丟失；5. 在“會(huì)話”選項(xiàng)卡中可查看並斷開(kāi)用戶連接；6. 使用命令行工具net file和net session可實(shí)現(xiàn)腳本化或遠(yuǎn)程管理，如net file列出打開(kāi)文件ID，net file /close關(guān)閉指定文件，net session查看會(huì)話，net session \\IP /delete斷開(kāi)會(huì)話；執(zhí)行這些操作需具備主機(jī)管理員權(quán)限且Server服務(wù)正在運(yùn)行，也可遠(yuǎn)程連接計(jì)算機(jī)管理進(jìn)行操作，結(jié)合圖形界面與命令行工具可高效管理共享文件。

If you're managing a file server or shared folder in a Windows environment, you may need to see which files are currently open by users on a network share — especially when troubleshooting locked files, high resource usage, or preparing for maintenance. Windows provides built-in tools to view and manage these open files without needing third-party software.

View Open Files Using Computer Management

The most straightforward way to see open files on a network share is through the Shared Folders section in Computer Management .

1. Press Win R , type compmgmt.msc , and press Enter.
2. In the left pane, expand System Tools > Shared Folders .
3. Click on Open Files .

Here, you'll see a list of all files currently opened by users on the system. Each entry shows:

• The name and path of the open file
• The user who has it open
• The number of locks (if any)
• The open mode (read, write, etc.)

Note: This view only shows files opened through network shares, not local access.

Manage Open Files: Close or Disconnect

From the Open Files list, you can take action:

• Close an open file : Right-click the file and select Close Open File . This forces the file to close, which can be useful if a user forgot to close it or is causing a lock.
• Warning : Users may lose unsaved data if you close a file forcefully.

You can also go to the Sessions tab in the same Shared Folders section to see which users are connected to the system, what computer they're using, and how long they've been connected. From here, you can:

• Disconnect a session
• See how many open files a user has

This is helpful when you want to take a server offline or suspect unauthorized access.

Use Command Line (Optional for Automation)

For scripting or remote management, use the net file and net session commands.

• Open Command Prompt as Administrator.

• Run:

   net file

  This lists all open shared files with their IDs.

• To close a file by ID:

   net file <ID> /close

• To view active sessions:

   net session

• To disconnect a session (eg, from \192.168.1.100):

   net session \\192.18.1.100 /delete

These commands are useful in batch scripts or when managing servers remotely via PowerShell.

Permissions and Requirements

To view and manage open files:

• You must have administrative privileges on the machine hosting the share.
• The Server service must be running (it is by default).
• You can connect remotely to Computer Management by right-clicking "This PC" > "Manage" > connect to another computer (if allowed by firewall and permissions).

Tip: If you're on a domain controller or enterprise server, consider using Performance Monitor or Resource Monitor for deeper insights, though they don't directly list user-opened shared files.

Basically, use Computer Management → Shared Folders → Open Files for quick visibility and control. Combine it with net file commands for automation. It's simple, built-in, and effective for day-to-day file share management.
