Combination of renaming and move in one process

I'm not a big expert on this either, but I think you can click Tools in the menu, then Customize in the sub-menu.

When the Customize - Directory Opus window has appeared, right-click an empty area in a toolbar and select New -> New Button. After the new button appears on the toolbar, (with the Customize Directory Opus window still open) double-click the new button, then click Advanced.

In the Command Editor - Directory Opus window, enter something meaningful in the Label field, then copy the code previously shown here into the area at the bottom. Click OK a couple of times to close the customization windows.

Alternatively, instead of creating a toolbar button, you could create a context menu entry as follows:

Settings -> File Types

Select All files, or possibly Recognized images.

Click Edit.

Click the Context Menu tab.

Click New.

From here, it will be obvious how to proceed, I think/hope.
