I think a commandlet like this might work:<br><pre><code class="code-1 nolinks" id="code-20-43298634-1"><span>dir | rename-item -NewName {$_.name -replace "_gr","_gt"}</span>
</code></pre><br>I can't test now due to a sudden power outage. I will check back later. Thank you in advance. :)&nbsp;

Thank you NVIT. <br />

I'll try that when the power comes back. :)

FWIW I still use Bulk Rename Utility to do this.<br />
<br />

<br />
It's simply a GUI that writes and runs this for you.<br />

And if you wanted to go the DOS BAT route, here's a small example of an approach there...<br />
<br />

<pre><code class="code-10 nolinks" id="code-20-43298735-1"><span>@echo off</span>
<span>setlocal EnableDelayedExpansion</span>
<span></span>
<span>set BaseDir=B:\EE\EE29217667</span>
<span></span>
<span>for /f &quot;tokens=*&quot; %%A in ('dir /a-d /s /b &quot;%BaseDir%\*_gr*.*&quot;') do (</span>
<span>    set OldName=%%~nA</span>
<span>    set NewName=!OldName:_gr=_gt!</span>
<span>    echo Renaming &quot;%%~A&quot; to &quot;!NewName!&quot;.</span>
<span>    ren &quot;%%~A&quot; &quot;!NewName!&quot;</span>
<span>)</span>
</code></pre>

Thank you all.<br><br>It turned out that the most useful (in my situation) commandlet was:<br>dir *.txt -rec | rename-item -NewName {$_.name -replace "_gt","_gr"} <br><br>Thanks again for your much appreciated support. :)&nbsp;

Windows 10 (command) - bulk rename multiple files/multiple folders

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Windows 10

Microsoft Disk Operating System (MS-DOS) was an operating system for x86-based personal computers, and traces of it are still found in the Windows operating system. DOS is still used in some embedded systems and for certain legacy 16-bit networks.
