Rename Files Like A Pro With RenameMaestro

I’m not a professional photographer, but I enjoy taking pictures with my smartphone. What I don’t like is the resulting filenames that are meaningless to me, yet appear to have some order. Instead of fretting about the situation, I found a great file-renaming utility called RenameMaestro. Although you may associate the name “maestro” with music, this software works on multiple file types, ranging from MP3s to photos to PDFs.

My Photo Problem

The problem I had was I took too many photos, which were stored on my phone. I transferred them to my PC, as I wanted to use some on a Facebook fan page. I ended up with an array of files that seemed identical but varied by date. The file names certainly didn’t provide a clue as to whether the subject matter was my Oregon trip, wine labels, twins, or something else. Does the example picture below look familiar to you?

After looking at the filenames, I figured I needed a way to rename files. My first thought was I could probably write a DOS batch program using the RENAME command. My second thought was the cold medicine I was taking was interfering with my thinking as someone has surely tackled this problem using Windows.

I was correct on the one hand as there are many file-renaming programs. I first tried other free ones and found them OK, but not easy. I know that probably sounds strange after my comment about writing a DOS batch file. I wanted a program I wouldn’t have to relearn each time I needed to use it.

The Interface

After doing more research, I found an application called RenameMaestro. At first glance, I thought maybe the program was too much for me as the opening line read “Looking for the easy way to batch rename files and folders by the million?” Uhm…no, I only had several hundred photos to rename. I quickly spotted another button that said “ 60-second Tutorials” with some amusing scenarios and I felt better.

In my case, I wanted to rename a batch of photos I took with the twins that I put in a separate folder. I dragged that folder from Windows Explorer and dropped it onto RenameMaestro.

I used the Single Action Home feature, as I wanted to replace the date portion of the file name (2011-02-07) with something that better identified the pictures (twins-fbfp). Next, I clicked Easy Rename and typed my descriptor in the textbox. At that point, the program previewed what the new file names would look like in the Renaming Preview section on the right side. You can also see in the example below, the program appended the sequence number to each file name. Until I hit the Rename!>> button, I could edit or undo my action. As you’ll see in a later screenshot, I changed the insert text value and added a hyphen.

Plenty of Options

In some cases, you may not want to rename the whole folder contents, but only files containing specific text in the file name. Again, renaming is very easy with a “search and replace” feature. In the example below, I wanted to rename photos from a certain date to reflect when I was in Oregon. I simply typed 2011-01-27 in the Find What textbox and oregon-trip in the Replace with textbox. The program also allows you to use various wildcards for letters and numbers. If I had more files with this pattern, I could save this “action” and reuse it later.

The program can do a lot more than what I demonstrated above especially when you build and save “actions”. When you play around with the options, you’ll see that you can extract Meta information from files and use those data elements as part of the file name. For example, with photo files, RenameMaestro can read the EXIF information . This is a nice feature if your camera captures geo-location codes.

File Information

I quickly found another use for this File Information feature. I constantly download programs I plan to review. Many times those file names are cryptic or have the generic name of setup.exe and by the time I get around to them, I haven’t a clue about the program. Now, I can drop my “saved downloads” folder in RenameMaestro, and presto I can see things like company, comments, version, file description, etc. without needing to rename files. Instead of seeing something like SFTPMSI.Exe and guessing what it is, I can now see it’s the setup file for Smart FTP. These Meta information fields also change based on file type so the MP3 files have different fields from a PDF file.

Program Sunsetted & Option

While this software has helped me for years, development on it has stopped. The developer is working on a new project called GitBreeze, which is a GUI for Git. Sadly, this means that it’s going to be difficult to find. There are several software repositories that contain old versions, but I’m reluctant to point people to them.

In the interim, Microsoft has added a feature to its PowerToys utility called PowerRename. It’s a bulk renaming tool that allows you to change file names in bulk or use search and replace. You can even use regular expressions.

The program is not as task-oriented as Rename Maestro but in some ways is more powerful since it does allow you to use regex. The program will add a “PowerRename” option to your menu when you right-click on a file within Windows File Explorer.
