Which command is used to determine file ownership in a Windows environment?

The command used to determine file ownership in a Windows environment is the "dir" command. This command provides a detailed listing of files and directories within a specified directory, including important file attributes such as file size, date of creation or modification, and ownership information. When you execute the "dir" command in the Command Prompt with the appropriate options, it displays the owner of each file in its attributes, which is essential for understanding permissions and access rights.

Other commands like "stat" are typically associated with Unix/Linux environments and do not apply to Windows, while "list" and "open" are not standard commands used to retrieve file ownership in Windows. Thus, the "dir" command serves as the correct choice for identifying file ownership in a Windows context.
