Bulk Rename Utility

Bulk Rename Utility is a file renaming program for Windows that renames files and folders in bulk. You can add, replace, or insert text, change letter case, add auto-numbering, and remove or change extensions, and you can preview the new names before renaming. Advanced options include regular expressions, JavaScript, directory recursion, and renaming photos from EXIF data. It is free of charge for personal, private use at home, and a commercial license is required for business or commercial use.
