Windows comes with a variety of ways to rename multiples files at once from Windows Explorer, the Command Prompt, or PowerShell. Whether you're looking for an easy-to-use graphical interface or a powerful command-line method, you?ll find it here. The Windows Explorer method is fast, but lacking in flexibility. PowerShell is extremely flexible ? but it can be intimidating if you're new to PowerShell. If you?re looking for a powerful graphical interface, a third-party utility is your best bet.
