Method 4. How to Find and Remove Duplicate Audio Files via PowerShell

If you are looking for a programmatical way to detect and eliminate duplicate music files, this is the right section. Here, we are going to use the script given below to compare files based on certain aspects such as file names, sizes, or content. Then, deciding which files to delete or keep. 

  • Right-click on the Windows button. Then, go to Windows PowerShell (Admin). Copy and paste the code given below.

Here is the code instance:

# Set the path to your music folder

$musicFolderPath = “C:\Path\To\Your\Music\Folder”

# Get all music files in the specified folder

$musicFiles = Get-ChildItem -Path $musicFolderPath -Filter *.mp3

# Group files by name and size to identify duplicates

$duplicateGroups = $musicFiles | Group-Object -Property @{Expression={$_.Name + $_.Length}} | Where-Object { $_.Count -gt 1 }

# Iterate through duplicate groups and keep one, delete the rest

foreach ($group in $duplicateGroups) {

    $group.Group | Select-Object -Skip 1 | ForEach-Object {

        Write-Host “Deleting duplicate file: $($_.FullName)”

        Remove-Item -Path $_.FullName -Force



Note: Don’t forget to replace “C:\Path\To\Your\Music\Folder” with the actual path to your music folder. We will recommend you run the code on a small set of music files at first. Or have a backup of the required data before proceeding. 

Method 5. How to Erase Identical Music Files on Windows PC through CMD?

This segment will study the usage of the Command Prompt (cmd) on the computer to find and delete duplicate MP3 files. This built-in application has a powerful feature i.e. fc (File Compare) command. Here’s a step-by-step guide:

  • Press Win + R to open the Run dialog box.
  • Next, enter cmd and press Enter.
  • After that, use the cd command to navigate/change the directory. 
  • Run the following code to get a text file that contains a list of all the music files (like MP3, MID/MIDI, OGG, AAC, RealAudio, VQF, etc.) present in the directory: 

dir /b /s *.mp3 > filelist.txt

  • Now, use the FC command to compare the files and find the duplicates more effectively. Here, we will use a for loop to iterate the scanning through the list of files. The idea is to compare each file with all other music files in the folder.

for /f “tokens=*” %a in (filelist.txt) do (

    for /f “tokens=*” %b in (filelist.txt) do (

        if “%a” neq “%b” fc /b “%a” “%b” > nul && echo Duplicates: “%a” “%b”



This script will give you results by comparing each file with others in the list. At last, shows the message if duplicates are found. However, just for the sake of convenience, try to take a large number of files.
