Using My Computer or Windows Explorer, open the folder containing the files. Select all the files you wish to rename (use Shift or Ctrl to select multiple files).

Note: In this example the files are already numbered sequentially – this is how digital cameras create temporary file names. We still want to create a numbered sequence, but we want better names.

Right-click on the first file in the list and select Rename from the context menu.

Type a new name for the file, then hit Enter. We’ll call the first file picnic.JPG – the other files will automatically be given the same name followed by numbers in parentheses.

You’ll notice that the first file has the exact name you entered, without a number. If you want the numbering to start from the first file, enter the file name followed by the number (1). You must enter it exactly like this – the file name, a space, and the number 1 in parentheses.

Note: If you make a mistake, you can undo the renaming by selecting undo from the edit menu, or by pressing Ctrl-Z (repeatedly).
