Extremely (extremely!) powerful file/folder renaming tool (allows for batch renaming).

Today I will leave out the the usual brouhaha and cut right to the chase. I am here to tell you about an extremely powerful freeware file/folder renaming tool (if you somehow missed what the title said =P):


Rename Master is a complex, yet elegant (in a weird way), software that allows to you rename files/folders in multiple different ways:

  • Add characters/words to the beginning/end of file/folder names.
  • Add characters/words at a specific location in the name of files/folders.
  • Add characters/words before/after a specific phrase.
  • Replace names/phrases.
  • Replace characters.
  • Replace numbers.
  • Remove words/numbers.
  • Remove characters from the beginning/end of file/folder names.
  • Remove “substring”.
  • Remove everything before/after a phrase.

***Note: By default Rename Master is set to only allow you to rename files. If you want to be able to rename folders also, click on 2009-03-23_212024 and select “Files and Folders” under “File List”.

You can use just one of the above or you can use them in combination with each other. You can select just one file/folder to rename or you can select multiple files/folders (but this program is intended for multiple file/folder use because, well, you could just as easily rename a single file/folder yourself).

Here is the full feature list (besides all that I mentioned above) for Rename Master:

  • Intelligent number sorting
  • JPEG/MP3 tag support and many more Meta-Variables
  • Auto-Preview support
  • “Scipts” to save commonly used renaming options
  • [*] and [?] command prompt style wildcards for replacing and remove options
  • “Undo” button so a renaming operation can be rolled back
  • Floating thumbnail window for viewing pictures and optional thumbnail file list view
  • Optional Explorer integration for right-clicking on folders or using “Send To”

Yes I know the features list and the interface for Rename Master are very confusing (it comes with the territory unfortunately). To mitigate the learning curve, the developer has included a very helpful tutorial (you can find it under “Help”):

  • “Getting Started…” tutorial:





Clicking on 2009-03-23_204624 allows you to add all the renaming options I mentioned above.


The tutorial the “Preview”, “Rename” and “Undo” buttons are mentioned but it is not very clear what those buttons are. No worries – I will show you =D:


The first one is “Preview”, the second one is “Rename” and the third one is “Undo”.

Additionally there is a “Renaming Options Wizard” that you can also find under “Help” if you need further direction.

The beauty of Rename Master is you can make it as simple or as complex as you want it to be; you can do straightforward renames or complicated ones. Rename Master is truly for the tech guru and tech not-so-guru (once you learn how to use it of course).

Rename Master works for all types of Windows. When you download and unzip Rename Master two files will be extracted, Renamemaster.exe and setup.exe:


Rename Master is a standalone portable application (yes you can place it on your flash/thumb drive) so you do not have to run setup.exe – it is optional. Just run Renamemaster.exe to start the program. However note that after you run Renamemaster.exe about 10 files are created in the folder that Renamemaster.exe is located:


So just don’t place Renamemaster.exe on your desktop (rather place it in a folder by itself and create a shortcut to it on your desktop).

Have I convinced you to get Rename Master yet? If not I quit (just kidding – don’t get your hopes up =). You can grab Rename Master from the following links:

    I use KrojamSoft BatchRenameFiles Tool because it an quickly and easily change the name, attributes of files/folders. It can also sort file names by name, date, time

  • Len Richards

    Ever download files where there is an underscore between each word or some other junk. Awful
    eg: battle_of_the_lost_men_ and on and on. There is one music site I use quite often and all the files have that irritating undersccore between each word, or the file contains the name of the user who posted the file.
    It would take forever to remove this stuff (thousand of files) manually, unless you know awk, sed, etc

    @Mike: Mike, I used Oscar’s Renamer a LOT, it was the best tool I found for renaming many files. It was so easy to “repair” names in a folder, just type over anything you want to change. And it had a macro recorder that would let you record a change and play it back on any other filename. Quick and easy. Sadly, it didn’t work in Vista. I wrote the developer and he said was thinking about updating the program but didn’t know when, or if, that could happen. As I recall, the macro capability no longer worked and it prevent my right-click (context) menus from working much of the time. So sad, this was really one of the most perfect programs ever written! And looks like it’s still the old version 1.1, last updated in 2007.

    All I have to say is WOW why do you need this? Someone had an example above and said this—>

    ” Suppose you have taken a vacation with 200 jpgs named DCS-00345.jpg, DCS-00346.jpg, DCS-00347.jpg, DCS-00348.jpg, etc.

    Wouldn’t it be nicer to see them in your PC as 2008-July-5 Family Riviera Beach 001.jpg, 2008-July-5 Family Riviera Beach 002.jpg, 2008-July-5 Family Riviera Beach 003.jpg, 2008-July-5 Family Riviera Beach 004.jpg, etc? <— ya this program probably does do this for easy renaming, but if you wanted to save yourself the hassle of downloading "another" software to your already bogged down pc. Why don't you just use windows tip for renaming. It's easy. Example…if you want to rename a bunch of pictures per say. All you need to do is type ctrl + a, next right click any picture and select rename, and rename it to whatever you want. After you click off of that all the pictures you selected will be what was done above without using another piece of software. ;)

    The most powerful freeware renamer I have come across is metamorphose…A beast of a renamer! Check it out Ashraf…

    Btw Pious Ramadhan.

    I will have to try this and Flex Renamer out…but not sure if they’ll replace my mainstay for the past number of years. I remember using some other renaming tools years ago, but once I ran across Oscar’s Renamer, I haven’t found a dire need for anything else…it’s basic, and probably not as full featured as other tools, but it’s a quick and dirty tool that absolutely rocks for what it does. Sort of a free-form renamer….so ultra handy when you just need to rename a handful of files, but don’t want to go through manually in Explorer and do them. Also good for search and replace….sort of a cross between a text editor and a renaming tool:


    Mediachance has other cool software (shareware) that are excellent as well, but the Renamer is an awesome freebie must have in my opinion.

    Thanks for reviewing these others, as it’s always good to try stuff that works well. Will defniitely try them out.

    I’ve seen reviews of these renaming utilities constantly, but the one I keep going back to is Jim Wiltsher’s Bulk Rename Utility (as previously mentioned). It does everything. Unfortunately, Jim sold the site a year or two ago and doesn’t update the program. I’m not sure if the new owner of the site is updating it, but I think old versions are available in the usual places (oldapps.com, oldversion.com, a+software, etc.)

  • Ah, but did you use the powerful tools offered to you by the God of the Internet, mighty GOOGLE?!?!?!

  • Jean-Luc Picard: That’s exactly what I said.

  • Liam,

    What did you think I made it up? :P

  • Jean-Luc Picard: :P

    Ashraf: Woah, brouhaha is in the dictionary.

  • @ashraf:
    your second usage example:

    Someone is working on a project and they decide to change their file naming convention in the middle of the project.

    is a baad idea. You should decide on a convention and finish it.

  • gmon,

    I actually ran into Bulk Rename while doing some research for Rename Master. I was debating which one to post about; in the end I decided Rename Master because I felt that it was easier to use (as you have observed) without compromising any features (that I noticed anyway).

  • gmon

    I have been using Bulk Rename for years, free and does everything you can imagine and some things you never even thought of. RenameMaster might actually be easier to use, so I will give it a try, but check out Bulk Rename:

  • Jeanjean

    I use “FileMenu Tools”, a free soft from Lopesoft (to manage the Shell).
    It has an option called “Advanced Renamer” witch is added at the right clic Menu.
    I think the possibilities are the same and you can also immediatly see the result.
    I’ll try yours …
    Thanks !

    Why use them? Suppose you have taken a vacation with 200 jpgs named DCS-00345.jpg, DCS-00346.jpg, DCS-00347.jpg, DCS-00348.jpg, etc.

    Wouldn’t it be nicer to see them in your PC as 2008-July-5 Family Riviera Beach 001.jpg, 2008-July-5 Family Riviera Beach 002.jpg, 2008-July-5 Family Riviera Beach 003.jpg, 2008-July-5 Family Riviera Beach 004.jpg, etc?

    That’s just one reason to own a renamer if you own a digital camera at all. If you don’t own one or take pictures with the one you have then I’ll agree that a renamer is not the great utility the rest of us love to use. It’s a must for us camera buffs.

    My favorite renamer is Freeware called FLEXRENA (Flexible Renamer).
    I helped the Japanese author in its early days with English translations. Now I’m off to try this one that Ashraf has recommended we try. I may like it better. Hell, I may just own two renamers … they’re free!

    “Free is good, Free is affordable” – my saying to you all.

  • Example:

    • I may want to add “dotTech.org” to the end of all the file names for my screenshots.
    • Someone is working on a project and they decide to change their file naming convention in the middle of the project.
  • I’ve never understood why people would need these batch renamers…can someone give me an example?
