Rename X is powerful, easy and secure. The combination of a clear preview, the ability to undo and the use of presets make it the best rename utility. Best price too.

What a disaster

I got a response to my review (and email to the developer). They were very good about addressing my concerns and the app does what I need. But only four stars because I think they've erred on the side of too much extraneous functionality at the cost of clarity and simplicity.

I just updated my iMac to Catalina and updated from Rename to Rename X. What a mess.
I use a folder of about 1000 - 1200 images and they are named with a sequence number and description.
I remove images from the folder to use them in essentially random order, and add new images to the end of the sequence. Keeping them in sequential order is important for my workflow. I periodically renumber the images to get rid of the empty spots - I’ve been using Rename to remove the 4-digit sequence number, renumber them with a 5-digit sequence number (to avoid possible duplicate names), and then remove the initial sequence digit.
When I used Rename X for the first batch rename of my image folder, the images were renumbered in essentially random order.
Now my reference folder is useless and I need to find an app that can support this simple use case.

Hi Ken,

This sure sounds like a mess.
Rename X is designed to be powerful but simple to use.

I think the following steps will make renaming easy and just like you want it.

The Basics
- Always use the preview to see if the results will be as you want them to be.
- Only rename files when you are sure the preview is what you need

Sorting is essential when doing sequential rename batches
- Use the Sort button menu (left bottom of the window) to sort the original files
- Check the preview to see if the result is OK

When something goes wrong
- Mistakes do happen. Rename X has an undo option.
- Click the Show History button, check the files you want to undo and rename again. Solved.

The simplicity yet powerful options of Rename X should make every remains batch a breeze.
If things turn wrong for some reason, just use the undo option.

I hope Rename X will deliver the results you need in the future.
Let me know if you need further assistance.

Greetings, Gijs

Best File Renaming App & Worth The Price

The is the best file renaming app I’ve found and it’s reasonably priced. I’m writing this app needs to appear in the App Store search results because it’s works well, has a lot of options, and is really simple to use and understand. I know it’s not free but it’s worth the 99 cents.

This app was originally called Rename and I’ve been using this app for years but after upgrading my Mac OS it never comes up in my App Store searches. So after searching and trying different free renaming apps for a while I finely found the developer online and found that they renamed it. Anyways, if you need to rename a bunch of files…this is the best app for it. Cheers.

More than a Rename App

This app does more than simply rename files. You can: Find a character string and replace with another string of different lengths; Add serialized numers at the beginning or end of file name; Remove characters of various lengths at either the beginning or end; Add a prefix or suffix of various lengths. and add or remove the file extension. And all of this can be done in a single pass. The preview window shows you exactly what your renamed files will look like before you Rename. Note: this is an update in place and the original file names are only stored in the History file.
