Rename Multiple Files at Once

Once all the files you want to rename are highlighted, press F2, or right-click on one of the files and select Rename. All of your file selections will disappear except for one, but don't panic: Type in your new name and click Enter. That's it! One file will be now be named "renametext" and the others will have sequential numbers in the format of "renametext (1)" and "renametext (2)" and so on
