Once Renamer

Once Renamer is a tool to change the name of several files very quickly and with just a click.

The process is very simple: import the files you want to rename, edit the names (or the extensions), and process the changes. In a matter of seconds you'll see the results.

Once Renamer performs a very specific task and does it very well. Its interface is also very comfortable (although it's a little outdated) and you don't need to install it, meaning you can take it with you anywhere on your USB device.
