Which of the following commands shows you the names of all open shared files on a server and number of file locks on each file?

The net file command is a standard Windows command-line utility used for network administration and live system analysis. Its specific function is to display a list of all shared files that are currently open on a server by remote users. The output includes the file's unique identification number, its full path, the name of the user who has it open, and, crucially, the number of locks currently placed on the file. This command provides a real-time snapshot of file access activity over the network, which is essential for both administration and forensic investigation.

A. Net sessions: This command lists or disconnects user sessions between the server and clients, but it does not provide details on individual files being accessed.

C. Net config: This command is used to display and modify the configuration settings for core network services like 'Server' or 'Workstation', not for viewing active file usage.

D. Net share: This command manages the shared resources themselves (e.g., listing, creating, or deleting shared folders), but it does not show which files within those shares are open.
