Bulk Rename Utility

To rename files to have sequential numbers and lowercase file extensions, you can use Bulk Rename Utility. This guide was written by Guy.

Step 1: Select your files

  1. Open the software and navigate to your folder using the navigation tree on the left.
  2. Highlight the files you want to change (press Ctrl+A to select all files in that folder).

Step 2: Set the New Name (Box No. 2)

  1. In the Name (2) box, change the dropdown menu to Fixed.
  2. Type your desired name in the text field (e.g., Experiment_Data_).

Always add an underscore or a space at the end of the name.

Step 3: Add Sequential Numbering (Box No. 10)

To make the numbers automatically appear after your text.

  1. In the Numbering (10) box, set the Mode to Suffix.

Step 4: Format the Extension (Box No. 11)

To ensure all file extensions (like .JPG or .PDF) are converted to lowercase (.jpg or .pdf).

  1. In the Extension (11) box, change the dropdown menu to Lower.

Step 5: Review and Apply

  1. Look at the New Name column (the orange text). Verify that the name, numbers, and extensions look correct.
  2. Click the large Rename button at the bottom right corner.
  3. Confirm the action in the pop-up window.
