The app does most everything needed to replace a program I use on another PC. The only item I don’t like is that it updates all the files in the folder. I haven’t discovered a way to only rename selected files. It would be helpful for the app to only change the selected files instead of all that are in the folder.

This is a very good app, except for two major and three minor flaws:The first major flaw is that it only operates on whole directories of files. There is no way to select individual files or a group of files. You can drag-and-drop folders onto the app, but not files. The second major flaw is related: it doesn't remember the directory you just selected. If you click "open", it always starts in ~/ no matter what. Put together, these are very major barriers to usability in an otherwise good program.The other more minor flaws are related to interface. First, there is no need to separate tasks into different "category" and "action" dropdowns. There are only 19 actions in all, and some of those do not need to be separate actions; it would be easy to combine them into one. (Example: "Add date/time to beginning" and "Add date/time to end" could easily be made one "action", Add date/time, with a checkbox for beginning or end.) So some actions could be combined, and all of them put into one dropdown list.The last flaw is admittedly a very minor quibble, but the word "suffix" is misspelled in the dropdown.Clean up the interface, combine those "actions" that can be combined, and allow it to work on collections of files, not just whole folders, and this would be 5 stars easy.

Somewhat intuitive user interface has enabled me to do several things I have needed to do for years at work. I have a "template" created of a hierarchy of folders and subfolders each named for a specific type of client document followed by "LAST, First" for an individual client name. For years I have had to spend around 5 minutes creating an electronic file for a new client by manually going through the 30 to 40 folders replacing "LAST, First" with "DOE, John."Rename Master lets me do the same task in about 5 seconds! I am also able to quickly go through entire client files correcting errors others have mande when naming individual documents. It is a life saver!

Perfect tool for what I needed to do. Tried another that looked slick and seemed to be free, but got hit up for money to use each feature. This one is an honest basic tool and works great, once you know how to use it. Happy customer!
