Rename JPEG Files

There are plenty of file renaming utilities out there, but only a few are actually aimed at JPEG photos, so Rename JPEG Files may come in handy to lots of users.
Just like its name suggests, Rename JPEG Files is a Windows utility developed to rename JPEG files using EXIF data and based on a user-defined format.
The GUI is just plain and simple and seems to be the perfect choice for this kind of app. You're only required to pick the target directory, the one that holds the JPG files, and input a file name format, with the list below showing both the original and the converted file name.
Tweaking the file name format is not that difficult and the build file name format screen lends you a hand, showing all codes and their descriptions. Simply double click a code to add it to the name.
As for the pictures that do not contain EXIF data, they can't be processed and they are marked with yellow in the main window of the app.
The renaming process doesn't take more than a few seconds and the overall computer stability is not affected at all. Administrator privileges aren't required, so anybody can use it just fine.
Another thing that's worth mentioning is that Rename JPEG Files comes as a stand-alone executable file, so it's fully portable and doesn't need to be installed.
All in all, Rename JPEG Files is undoubtedly a helpful app, although we all agree that certain improvements are still necessary. For example, future updates to handle pictures without EXIF are a must have.
