How to Add a Prefix to Multiple Files in Windows with One Click (The Ultimate Automation Guide)

When managing digital files, we often need to prepend a specific prefix (such as Project_, Final_, or 2026_) to hundreds of files at once. Doing this manually, one file at a time, is incredibly tedious and time-consuming.

In this guide, you will learn how to create a custom automation script integrated directly into the Windows "Send to" (Right-Click) menu. Once set up, it will instantly add any prefix you want to all selected files—without altering the rest of their original file names.

How It Works

This automation utilizes a blend of a standard Windows Batch (.bat) script and native VBScript:

1. You select your files, right-click, and trigger the script.

2. The script launches a native graphical Input Popup Box asking for your prefix.

3. Once you type the prefix and hit Enter, a background loop renames all selected files instantly and closes itself silently.

Step-by-Step Setup Guide

This is a one-time setup. Once configured, it will work forever across your system.

Step 1: Create the Automation Script

1. Right-click on an empty space on your Desktop.

2. Navigate to New > Text Document to open a blank Notepad file.

3. Copy and paste the following code exactly into the Notepad window:

@echo off
setlocal enabledelayedexpansion

:: 1. Opens a graphical popup box asking the user for a prefix
set "vbsfile=%temp%\prefix_prompt.vbs"
echo strInput = InputBox("Enter the prefix you want to add:", "Bulk Prefix Adder") > "%vbsfile%"
echo WScript.Echo strInput >> "%vbsfile%"

for /f "delims=" %%A in ('cscript //nologo "%vbsfile%"') do set "prefix=%%A"
del "%vbsfile%"

:: 2. If the user cancels or leaves it blank, exit the script safely
if "%prefix%"=="" exit

:: 3. Loop through all selected files and rename them
:loop
if "%~1"=="" goto end
ren "%~1" "%prefix%%~nx1"
shift
goto loop

:end
exit

Step 2: Save the File Correctly

1. In Notepad, click on File > Save As... in the top left corner.

2. In the File name field, type: Add Prefix.bat

3. In the Save as type dropdown menu, strictly select All Files (.).

4. Click Save. You will now see a file on your desktop with a gear icon.

Step 3: Move to the "Send To" Menu

Now, we will place this script into Windows' native shortcut folder so it appears in your right-click menu:

1. Press the Windows Key + R simultaneously on your keyboard to open the Run dialog box.

2. Type the following command and press Enter:

   shell:sendto

3. A system folder will open. Cut and paste (or drag) the Add Prefix.bat file from your desktop into this folder.

How to Use It in Action

Your high-speed file automation shortcut is officially ready!

1. Select: Highlight all the files you want to rename.

2. Right-Click: Right-click on any of the highlighted files.

3. Send To: Hover your mouse over Send to and click on Add Prefix.

4. Input Prefix: A small prompt box will appear. Type your desired prefix (e.g., Office_, Data_, or 2026_).

5. Press Enter: Click OK or hit Enter.

All selected files will be renamed in the blink of an eye!

Why This Method is Better Than Software

• 🚀 Blazing Fast: Whether you select 5 files or 500, the process finishes in microseconds.

• 🛠️ Zero Third-Party Software: You don't need to download sketchy or heavy renaming applications from the internet.

• 🛡️ Safe and Clean: It uses core Windows system commands, ensuring your files are never corrupted and only the front part of the filename is modified.
