# Numbering files

You can use Renamer to number files. Renamer supports numbering with digits (1, 2, 3, …) and letters (a, b, c, …).

## To number files:

Drag the files you want to rename from the Finder to the file table.

Click and choose Numbers.

Choose the number format from the Numbering pop-up menu. You can choose between digits (with optional zero padding) and letters (lower or uppercase).

Click Apply.

To start numbering files from a number other than 1 (or A if numbering with letters), enter that number in the “Start number” box.

To number files in increments other than 1, enter the increment in the “Step value” box. For example, to number files with even numbers, enter a step value of 2 and choose an even number as the start number (such as 2). Similarly, to number files with odd numbers enter a step value of 2 and choose an odd number as the start number (such as 1).

By default, Renamer will append the number to the existing filenames. For example, the files “Apple.jpg”, “Banana.jpg” and “Orange.jpg” would be renamed to “Apple1.jpg”, “Banana2.jpg” and “Orange3.jpg”. To have the number appear before the filename, choose “Number – text – original” from the Format pop-up menu.

To insert text into the filenames, enter that text into the “Attach text” box. From the Format pop-up menu choose “Original – text – number” to have that text inserted before the number, or “Number – text – original” to have it inserted after the number.

By default, Renamer will include the original filename in the new filename. To discard the original filename from the new name, choose either “Text – number” or “Number – text” from the Format menu, depending on whether you want the number to appear after or before the attach text.

If you plan to drag in more files and would like Renamer to keep numbering without resetting the start number, select “Continue numbering”.
