Rename Multiple Files Using a Third Party App You can learn more about PowerShell in general from our Geek School guide, and learn more about the rename-item commandlet from Microsoft’s TechNet Library. And, of course, you can also build more complicated commandlet structures that even include IF/THEN logic. For example, the rename-item commandlet also offers features like a -recurse switch that can apply the commandlet to files in a folder and all folders nested inside that folder, a -force switch that can force renaming for files that are locked or otherwise unavailable, and even a -whatif switch that describes what would happen if the commandlet was executed (without actually executing it).

The rest of the commandlet just signifies that any space ( " " ) should be replaced by an underscore ( "_" ). The -replace switch indicates that a replacement is going to happen. The $_.name part stands in for each of the files getting piped. The dir part of that commandlet lists all the files in the folder and pipes them (that’s the | symbol) to the rename-item commandlet. From the “File” menu, point to “Open Windows PowerShell,” and then select “Open Windows Powershell.”ĭir | rename-item -NewName The quickest way to open a PowerShell window at your desired location is to first open the folder in File Explorer. Pipe the output of Dir to Rename-Item and you’re in business. Using PowerShell, you can pipe the output of one command-known as a “commandlet” in PowerShell terms-to another command, just like you can on Linux and other UNIX-like systems. The two important commands you’ll need are Dir, which lists the files in the current directory, and Rename-Item, which renames an item (a file, in this case). PowerShell offers even more flexibility for renaming files in a command-line environment. If you’re interested, the folks over at the Lagmonster forums have an excellent writeup on the subject.
