Getting Started
Use as a Stand-Alone Application
Use A Better Finder Rename as a normal application: double-click it, then drop files into the preview list or add them with the + button and the Open dialog.
Simply double-click the application icon and the main window will appear.
You can now drag & drop the files you wish to rename from the Finder into the preview list on the right-hand side, or
you can press the + button at the bottom of the preview list to bring up a file selection dialog.
