Reimagine the Bulk File Rename Utility icon in a minimalistic, flat blue style consistent with previous icons. Depict two overlapping blue document icons, one with a large 'B' and the other with a large 'A'. Include a blue arrow pointing from the 'B' document to the 'A' document. Use almost exclusively shades of blue with clean, simple lines. Prioritize clarity, recognizability, and consistency with the other icons. Fully transparent background, minimal use of other colors.emoji
