How to change existing numbers

Case: Change an existing number in the filename to a new number, either from a new starting point or relative to the existing number.

If your files contain numbers that are out of order or formatted inconsistently, the Renumber method in Advanced Renamer can help. It detects numbers in filenames and replaces them with new values—either from a specific starting point or by adjusting them relative to the original number.

Here is how to do it:

1. Add the files to the list.
2. If there are methods in the method list, click the Clear Methods toolbar button.
3. Add the Renumber method and configure it as follows:
   Number position: If the file has multiple numbers, select the one you want to change, otherwise use 1.
   Change to: Set to one of the following:
   • Absolute: Replaces existing numbers with a new sequence starting from a chosen number.
   • Relative: Adjusts the existing number by adding or subtracting a specified value
   New number/Number difference: Enter the new number or the difference to use.
   Zero padding: Can have one of three values:
   • Automatic: Automatically pads the number with zeros based on the length of the existing number and the number of items in the list.
   • Manual: Pads the number with a fixed number of zeros. Enter the number of zeros in the field.
   • No padding: No extra zeros applied.
   Apply To: Name
   
4. Verify the names in the list and click Start Batch.
