What is Smart File Renamer?
Smart File Renamer helps you rename large groups of files with custom rules instead of editing each name manually. You can add or remove text, change letter case, use regular expressions, insert dates, and add sequential numbers. The app supports multiple rules in one renaming task and shows a live preview before changes are applied. Smart File Renamer also detects naming conflicts, saves reusable presets, processes subfolders, and lets you restore original filenames with session-based undo.
