DnD Renamer

DnD Renamer is a lightweight application designed for batch renaming files using patterns. You can tinker with options in the configuration panel, after which you can save settings and drop files into the window or the .exe file to rename them on the spot.
It's not wrapped in a setup pack, so you can save the program files in any part of the hard disk and double-click the .exe to launch the tool. It saves the configuration details in an XML file and requires .NET Framework to work properly.

Set the file renaming pattern

In the configuration panel, you can check out the default naming pattern and change it into anything else. The supported naming patterns are listed in the "Help" section, and they are available for the original file name, file ID, day, month, year, hours, minutes and seconds. Several syntax samples are provided for applying multiple strings.
It's possible to rename the original files or create new copies, as well as sort multiple items by the name, date of creation or last modification. In addition, you can create a list with files to rename according to their extensions, in case you want to exclude all files that don't match the specified formats. Log details are recorded in a separate area, so you can examine program activity with any encountered errors.

Evaluation and conclusion

The application carried out file renaming jobs rapidly in our tests, during which it remained light on system resources consumption. It worked smoothly, without triggering the operating system to hang, crash or prompt error messages.
All in all, DnD Renamer comes equipped with handy options for renaming files in bulk. However, it may take a while to get used to the syntax, especially if you're not familiarized with this type of software. We must also take into account that the product remained in beta development.
