[Windows] Bulk rename files and modify file extensions with spacetornado Renamer

rtyryspacetornado Renamer is a brilliantly simple tool, but one that is most certainly necessary. All to often we’ve come into contact with files with the same names, files that are named the wrong way, situations where we are looking to organize our file names in some way, etc. This program can help you batch rename massive amounts of files in one go.


Main Functionality

spacetornado Renamer is a batch file renaming program for Windows.


  • Can do the following to file names: add text, replace text, change letter case, and remove characters
  • Allows you to pick if you want to modify file extensions or not
  • Supports batch processing
  • Very straightforward user interface
  • Works fast and has low memory footprint


  • The last update for this program was in 2006, so development may have finished or has stalled (but it does support the latest versions of Windows, including Windows 8 if run in compatibility mode)


457Everyone has seen duplicate file names, poorly named file names, or confusing file names. It doesn’t really matter on the type of the file, sometimes you just have to rename a ton of files and you don’t want to do it one by one. That’s where spacetornado Renamer comes in. This program can help you rename an amass of files in a couple seconds. It is a very handy program, and operates itself very fast.

The main drawback about this program is that there hasn’t been any updates since 2006, but as I had no problems getting it to work on modern systems (7/8), I see no real problem. This really isn’t a program that needs any added features. It does exactly what it says it will do and it does it well. Want to rename a bunch of files? Put in the necessary things to do so. It’s really that simple.

The user interface even still does very well on modern systems. This is a program that has aged considerably well, and one that I can see myself using until something else comes along. There’s really not a lot to say about Spacetornado Renamer that hasn’t already been said. It can rename files in batch, replace words or characters, add text, and change characters at will. It’s a pretty useful program. I may keep it installed. I can see myself needing it in the future.


If you have need for a bulk file renaming tool — e.g. you have a ton of files that are named ‘filename(1).png’, ‘filename(2).png’, filename(3).png’, etc. and you want to rename them — you might want to check this program out. It can help you with your file naming woes. This program is very lightweight, and very straightforward, and one that everyone should at least check out. You never know, this might be just what you’re looking for.
