Easy Ways to Find Duplicate Files in Windows 11 / 10 / 8 / 7

March 16th, 2023 by Admin

How can I find duplicate files or images on my computer? After using the computer for a while, duplicate files may accumulate or clutter up your photo albums. If you are tired of duplicate files, you can use the following methods to quickly find duplicate files in Windows 11 / 10 / 8 / 7 so you delete them to free up disk space.

Method 1: Find Duplicate Files Using File Explorer

A duplicate file usually has the same name as the original file, but with the word “- Copy” in the file name. Using File Explorer you can easily find such types of duplicate files on your computer.

  1. Open File Explorer and browse to the location (for example, “This PC”) where may contain duplicate files. Enter the keyword “copy” in the Search box in the upper right-hand corner.

  2. Click the “Search options” button in the toolbar, make sure the “File contents” menu is unchecked.

  3. The system will quickly locate all folders and files which contains the keyboard “copy” in the file names. Then you may need to manually verify which files are duplicate.

Method 2: Find Duplicate Files Using Batch

  1. Open Notepad or other text editor, copy and paste the following code, then save the file with .bat extension and close it.

    @echo off
    setlocal EnableDelayedExpansion
    rem Group all file names by size
    for /R %%a in (*.*) do (
       set "size[%%~Za]=!size[%%~Za]!,%%~Fa"
    rem Show groups that have more than one element
    for /F "tokens=2,3* delims=[]=," %%a in ('set size[') do (
       if "%%c" neq "" echo [%%a]: %%b,%%c
    echo Press any key to exit
    set /p input=

  2. Move the newly-created .bat file to the location where you would like to scan for duplicate files, and double-click it to run the batch.
  3. It will check each file in the current folder and subfolders by file size. If two or more files have the same size, the batch will treat them as potential duplicate files, and display their file names in the same line but separated by a comma.

Method 3: Find Duplicate Files Using Freeware

If you want to find identical files in one or more directories with 100% accuracy, the freeware SearchMyFiles could be of help. This software is distributed as zip archive.

  1. Download SearchMyFiles from Nirsoft website. After unzipping, double-click the executable file in the extracted directory to launch the program.
  2. When the Search Options dialog box pops up, click the Browse button to add a target folder for finding duplicate files. If you want to scan duplicates across multiple folders or drives, just click the Browse button to add the locations one by one.

  3. Click the Start Search button. It will compare all files with equal size. When it find two or more files with identical content, they are added to the duplicates list in the main window.

  4. If you want to delete duplicate files, just select them and right-click to choose “Delete Selected Files” from the pop-up menu.

Create a Folder Starting with a Dot(.) in Windows 11 / 10 / 8 / 7

December 28th, 2021 by Admin

When you try to create a folder/file on Windows 7 that starts with a dot, like .htaccess, you may get the error message “You have to enter a filename“. To resolve this issue, you need to do it with Command Prompt. Since Windows 11, File Explorer allows to create and rename a folder whose name starts with a dot. In this tutorial we’ll walk you through the steps to create a folder starting with a dot(.) in Windows 11 / 10 / 8 / 7.

Part 1: Create a Folder Starting with Dot Using Command Prompt

Before getting started, open Command Prompt in the directory where you want to create a folder. You can then use the mkdir command to create a folder starting with a dot. For example, I can create a folder named .pcunlocker by executing this command:
mkdir .pcunlocker

or create an empty file named .tutorial.txt by running this command:

This method works with all versions of Windows, including Windows 10 / 8 / 7.

Part 2: Create a Folder Starting with Dot Using File Explorer

If you’re using Windows 11, you can create a folder starting with dot without using Command Prompt. Just open File Explorer and browse to your target location, right-click the blank area and select New -> Folder, and then type in a new name that starts with a dot.

File Explorer also lets you rename any existing folder by adding a dot in the front of its name.

How to Change Function Keys Behavior on Your Windows Laptop

October 28th, 2020 by Admin

F2 key doesn’t rename file in Windows 10? Function keys for brightness control (F11, F12) do not work any longer? Most laptops have a Fn key on the keyboard which can change the behavior of function keys (F1 – F12). On my laptop, the default function of F2 is to rename files, while pressing Fn + F2 will lower volume. If I accidentally activate the Action Keys (Hotkeys) mode, then F2 will lower volume and I have to press Fn + F2 for renaming files.

If function keys or the Fn key don’t work as expected, then you need to disable or enable Action Keys (Hotkeys) mode on your Windows 10 / 8 / 7 laptop.

Method 1: Disable or Enable Action Keys Mode from UEFI/BIOS

  1. Turn on your computer, immediately and repeatedly press a specific key (F2, F12, DEL, F10, ESC, etc.) to enter into the BIOS Setup. If you’re running Windows 10/8, you can access BIOS from Command Prompt, the Settings app or Windows sign-in screen.
  2. Once inside the BIOS/UEFI Setup, navigate to the Configuration Tab (Advanced tab or System Configuration tab) and look for an option called “Hotkey Mode” or “Action Keys Mode“, set it to Disabled or Enabled.

    On modern DELL laptops, select “Function Key Behavior” and press Enter to choose one of the following options:

    • Function Key – Disable Action Keys mode. Requires pressing Fn key to perform the actions printed on the function keys.
    • Multimedia Key – Enable Action Keys mode. Does not require pressing Fn key to perform the actions printed on the function keys.

  3. Now the behavior of the Fn key has been changed. Save and Exit the BIOS/UEFI Setup.

Method 2: Disable or Enable Action Keys Mode Using Fn Lock Key

The Fn Lock key is usually indicated by a lock icon with “Fn” printed on it. If your keyboard has a Fn Lock key, just hold down the Fn key and then press the Fn Lock key simultaneously, it will enable Action Keys mode. Pressing the Fn key and Fn Lock key again will disable Action Keys mode.

On some DELL or Lenovo laptops, the Fn Lock key is the Esc key. Pressing Fn + Esc can enable or disable the Action Keys mode with ease.


When Action Keys mode is enabled, function keys will work as multimedia keys by default. So you can press a single function key (F1 – F12) to mute/unmute the audio, adjust the volume or project to a screen, without having to hold down the Fn key. If you am very used to using the F2 key to rename files, just disable Action Keys mode and you’re good to go.
