Basically, I have an album of music and I want to remove the authors name from all of the mp3 files instead of having to manually do it myself. Is there a function in Windows 7 Ultimate that can do this for me?

You could also try using PowerShell, a powerful Windows command line tool. You'd run this command:

Full Command:

get-childitem *.mp3 | foreach { rename-item $_ $_.Name.Replace("Radiohead -", "") }

Analyzing it:

get-childitem *.mp3
This lists all files whose names end with .mp3.  They are then piped to the next command with the | operator.

foreach { rename-item $_ $_.Name.Replace("Radiohead -", "") }
This replaces all instances of Radiohead - with nothing, denoted by "", effectively wiping the word from all the files in the directory.

You could also modify get-childitem *.mp3 to get-childitem – that would rename all the files in the directory, not just files whose names end with .mp3.

    What does $_ $_. represent? Thanks!

    @paulkon it represents whatever item was piped through from the previous command. In this case, it represents each item as they're yielded by foreach loop. The $_. follows the dot notation to access properties/methods/elements. So $_.Name accesses the Name property of each file that is piped through by get-childitem.

    for recursive rename, just add -recurse parameter to get-childitem

    Thanks for this solution... worked a charm. I am sat here wondering how you get it to also modify files in sub-folders too? like how -R works on linux. I am a linux head. Nov 7, 2017 at 12:48

    Don't forget to add -LiteralPath if you have things like square brackets in the name. Other than that tyvm for this answer! Upvoted Jun 22, 2018 at 19:41

Forget about complicated scripts for this.

rename is a very old and never properly completed command. If you do not use it properly, the result might surprise you.

For example to remove a prefix abcd from abcd1.txt, abcd2.txt, abcd3.txt etc. in order to get 1.txt, 2.txt, 3.txt simply use

rename "abcd*.txt" "////*.txt"

You need the same number of / as the number of initial characters you would like to remove.

Do place double quotes for both arguments.

    No particular rule. It is as it is. / can be a part of unc path so it is not the same as : < > |. It is probably treated as some sort of invisible path.

    Fantastic discovery. Very odd that both source and target must be quoted, else get The syntax of the command is incorrect error. I'm curious if this technique has ever been posted anywhere prior to this answer?. I need to update my How does the Windows RENAME command interpret wildcards? Q&A, though technically, the / are not functioning as wildcards.

    Doesn't remove '.' in the file names. eg., dbo.table1.sql, dbo.table2.sql, it renames them to .table1.sql, .table2.sql

    For the above comments, you have to use the * wildcard. This answer should absolutely be the correct one. This is much simpler and more powerful then any obtuse powershell or batch script.

ReNamer can do that. In ReNamer, just add a 'remove' rule like this (a 'delete' rule will also work):

ReNamer 'remove' rule

And then drag and drop the files, or the folder containing the files you want renamed to its window (or use the 'Add Files/Folders' buttons), then check the preview, and once verified, click on 'Rename':

ReNamer window


This might work.

Create a batch file as follows:

for %%i in ("*.mp3") do (set fname=%%i) & call :rename
goto :eof
::Cuts off 1st four chars, then appends prefix
ren "%fname%" "my%fname:~4%"
goto :eof

    thanks. I saw this in google search but have to be careful with installing random software. given your rep and recommendation I installed it and it is incredible. No fiddling with powershell etc. I am a programmer and love the Trim, regex features. It works better than advertised. I highly recommend this too. ups! Mar 11, 2013 at 10:03

Since you are dealing with music files, forget about the batch file and utilities to rename your files. Use a dedicated program such as Mp3tag which is an absolute must if you're really into organizing your music.

Main features

Batch Tag Editing Write ID3v1.1, ID3v2.3, ID3v2.4, MP4, WMA, APEv2 Tags and Vorbis Comments to multiple files at once.

Support for Cover Art Download and add album covers to your files and make your library even more shiny.

Import from Amazon, discogs, freedb, MusicBrainz Save typing and import tags from online databases like Amazon, discogs, freedb, MusicBrainz, and more.

Replace characters or words Replace strings in tags and filenames (with support for Regular Expressions).

Create Playlists automatically Create and manage playlists automatically while editing.

Rename files from tags Rename files based on the tag information and import tags from filenames.

Export to HTML, RTF, CSV Generate nice reports and lists of your collection based on user-defined templates.

Full Unicode Support User-interface and tagging are fully Unicode compliant.

Besides these main features Mp3tag offers a variety of other functions and features ranging ranging from batch export of embedded album covers, over support for iTunes-specific tags like media type or TV Show settings, to combining multiple actions into groups that can be applied with a single mouse click.


I just want to add my favorite: Rename Master

This utility will add, remove, or replace parts of the filename with ease and also supports renaming via file properties, MP3 tags, JPEG JFIF and EXIF tags, Video tags, and text files. Batch renaming that's simple to use, yet still very powerful.

enter image description here


  • Portable mode
  • Intelligent number sorting
  • Full Unicode filename support
  • File and folder renaming
  • Custom filelist columns
  • Auto-Preview
  • Subfolder Scanning to rename files in multiple folder
  • Renaming Variables for JPEG/MP3/Video tags, file properties, counters, and more
  • Scripts to save commonly used renaming options
  • [*] and [?] command prompt style wildcards, or full Regular Expression support
  • Optional Explorer integration for right-clicking on files/folders or using "Send To"
  • Case Changing and Textfile importing
  • Command line options for batch renaming

I had a related requirement.

Take a backup of the folder on which you are trying the below commands.

Example 1:

CAUTION: This command overwrites a part of the existing file name

If you have only two files in a directory:

This is file 1.txt  
This is file 2.txt  

and if you run:

rename "\*.\*" "abc-\*.\*"  

Then, the files get changed to:

abc- is file 1.txt  
abc- is file 2.txt  

Example 2:

CAUTION: This command deletes a part of the existing file name

If you have only two files in a directory:

This is file 1.txt  
This is file 2.txt  

and if you run:

rename "T\*.\*" "/\*.\*"  

Then, the files get changed to:

his is file 1.txt  
his is file 2.txt

I was looking to svn rename a bunch of files with some common text. As I already had cygwin installed I ended up running bash:

bash-3.1$ for i in ipad_*; do svn rename $i ${i/ipad_}; done

I know TortoiseSVN sometimes prompts for common replacements but not in this case.


Go to cmd.exe and type in:

REN "Radiohead*.mp3" "*.mp3"

(With Quotes)

  • I just tested it. It does not work. Maybe due to the spaces in the file-names. (radiohead - 04 - testname.mp3)

    That's probably because what you are trying to rename it to (*.mp3). The asterisk includes the string "Radiohead", so basically you take all the files beginning with "radiohead" and renames it to the same as before, thus no effect. Jun 25, 2014 at 11:33
  • True. If the filename changes it works, as in: REN Radiohead*.log Mediahead*.log Sep 17, 2016 at 15:10

There's plenty of software out available specifically for doing this with music files. One example I've used is Tag&Rename. If you're looking for a general utility to use with any type of file, I'm sure they exist as well. But I don't have any examples off the top of my head.
