A lot of times I am required to rename large quantities of files according to various rules. Sometimes this task can take hours to complete. Today I had a job requiring me to rename all files in a program that contained "xi" with "nap". The program had thousands of files in a dozen different directories. It would have taken days for me to go through them all manually and replace ea. occurrence of "xi" in the file names with "nap", so I tested several tools to help me do the job. The most capable tool I found was named simply "ReNamer" and can be downloaded from:
I downloaded the "portable" version of ReNamer version 6.7 Here is a screenshot of ReNamer's simply UI:
How to Download and Open ReNamer for First Use
First things first, so here is how to get started:
Use the link https://www.den4b.com/products/renamer to download the portable version of ReNamer and it will download a zip file to your PC. Place the file on your desktop and right click it and select "Extract All". Windows will extract the files and probably open the folder for you. Then click on renamer.exe to start the app. You will see the UI as in the above image. I like using this portable version because it is very light-weight and can be used on any PC. When I'm done using it, I simply delete the entire unzipped folder but I save the .zip folder I downloaded so I can use it again when needed and it doesn't waste any space on my PC when it's not in use. Next time I need it, I simply extract the files again and use it. Then I delete the folder when done again.
Find and Replace Text in File Names of Many Files at Once
It is easy as pie to use too! It only took me a couple of test runs to achieve the renaming rules I needed to do the job at hand. Just click where it says "Click here to add a rule" and add a rule. I needed to find and replace text in the file names, so in my case, I clicked on "replace" in the left panel so the add rule screen looks like this:
All I had to do was simply enter "xi" in the "find" field and "nap" in the "replace" field and click the "Add Rule" button to save your new rule. Then all you have to do is drag the folder containing all the files you want to rename into the UI as in the first image above, where it says "Drag Your Files Here". Then it gives you a preview of what files it will rename. Once you are happy with how it's doing the renaming, click the "Rename" button in the upper right corner of the UI and it will rename all of the files just like it showed you. If you have tested any of the other features of this tool, please comment below and describe your experience!
